The emergence of the Middle Palaeolithic, and its variability over time and space are key questions in the field of prehistoric archaeology. Many sites have been documented in the south-eastern margins of the Massif central and the middle Rhône valley, a migration path that connects Northern Europe with the Mediterranean. Well-dated, long stratigraphic sequences are essential to understand Neanderthals dynamics and demise, and potential interactions with Homo sapiens in the area, such as the one displayed at the Maras rock shelter ("Abri du Maras"). The site is characterised by exceptional preservation of archaeological remains, including bones dated using radiocarbon (14C) and teeth using electron spin resonance combined with uranium series (ESR/U-series). Optically stimulated luminescence was used to date the sedimentary deposits. By combining the new ages with previous ones using Bayesian modelling, we are able to clarify the occupation time over a period spanning 200,000 years. Between ca. 250 and 40 ka, the site has been used as a long-term residence by Neanderthals, specifically during three interglacial periods: first during marine isotopic stage (MIS) 7, between 247 ± 34 and 223 ± 33 ka, and then recurrently during MIS 5 (between 127 ± 17 and 90 ± 9 ka) and MIS 3 (up to 39,280 cal BP).

ABSTRACT Recent excavations at the Middle Paleolithic site of Tinshemet Cave, Israel, showcase hominin burials and associated material culture that uniquely provide new information on hominin behavior in the south Levant around 120–100 ky ago. This study presents the site's stratigraphy in association with findings from sediment micromorphological analyses, shedding light on natural and anthropogenic site formation processes as well as human activities. Results indicate that two main types of sediment have been deposited—wood ash and reworked Terra Rossa soil—mixed to various degrees across the stratigraphic units. Hominin occupation started shortly after a partial roof collapse, intermittent with carnivore presence (Unit C). Hominin occupation increased and included the use of fire, flint knapping, cooking, and burial (Unit B), and increased even more (Unit A, Layer III) with more burials, intensive use of fire, cooking, knapping, trampling, and dumping. Anthropogenic sediments are largely cemented by secondary calcite that originates from recrystallized ash; however, intact hearths are absent due to syn‐ and postdepositional processes such as extensive bioturbation, cementation of the deposits, and trampling. Other postdepositional processes include fissuring and surface erosion. This study presents the importance of micromorphology to disentangle natural, anthropogenic, depositional, and postdepositional processes to better understand hominin behavior.

Objectives: Grotta‐Riparo di Uluzzo C (Apulia, southern Italy) is a pivotal site for investigating the evolution of the Middle Paleolithic and the earliest phases of the Upper Paleolithic in southern Italy, as the extensive stratigraphic record of this site includes a thick Mousterian sequence followed by the Uluzzian. Here, we investigate the taxonomic affinity of seven unpublished deciduous human teeth retrieved from the site of Uluzzo C in 1960. Materials and Methods: The teeth are represented by seven plaster dental casts, which are housed at the Museo Civico di Paleontologia e Paletnologia in Maglie (Lecce, Apulia). The location of the original specimens remains unknown, rendering these casts the only human remains evidence yielded by Uluzzo C to date. Based on occlusal‐view photographs and digital models of the casts, we examined the external morphology and morphometry of the teeth, comparing them to Homo sapiens and H. neanderthalensis samples. Through geometric morphometric methods and statistical analyses, we analyzed the crown outline of the deciduous molars. Results: The teeth show morphological and morphometric features that are variably found in H. neanderthalensis, H. sapiens, or both. Specifically, crown outline analysis shows that all molars fall within H. neanderthalensis variability, except for Uluzzo 853 (lower right deciduous first molar), which falls within H. sapiens variability. Discussion: This study provides the first taxonomic assessment of the hominin teeth from Uluzzo C. The results contribute additional insights into the Paleolithic peopling of southern Italy during a crucial period marked by the persistence of post‐Tyrrhenian Neanderthal techno‐complexes and the arrival of H. sapiens.

The cave of Saint-Marcel is known for its extensive network (64 km of galleries) and its history of human occupation (Middle Palaeolithic and Neolithic) in the entrance area. Close observation of the main network reveals areas with high concentrations of broken speleothems, which are usually attributed to the first tourist visits of the nineteenth century. However, archaeo-geomorphological mapping of the broken speleothems, many of which are lying on the floor and sealed by stalagmite regrowth or crust, indicates intentional organisation of the underground space into speleothem supply zones and zones in which the speleothems were used to build structures. Age estimates of the stalagmite seals on these human-made structures suggest that the structures were a result of human activity that occurred between the end of the Upper Palaeolithic and the European Mesolithic. These age estimates radically change the way we look at the broken speleothems in the cave of Saint-Marcel and the structures associated with them. They bring to light the engagement of past human communities with the deep underground environment, at more than 1.5 km from the cave entrance, which can only be accessed by crossing obstacles (pits) that, today, are considered as difficult to be crossed. Our findings and ongoing research stress the unequivocal archaeological significance of the cave. [ABSTRACT FROM AUTHOR]

Because it is often assumed that fundamental behavioral differences distinguish Neanderthals and Homo sapiens, the ability to structure space within the sites they occupied into distinct activity areas is often invoked as a key distinctive trait of our species. However, this behavior has never been assessed for both groups at a single site, hindering direct comparisons to date. To help resolve this question, this study uses a single methodology to evaluate the spatial organization in the Protoaurignacian levels (A1-A2, associated with Homo sapiens) and the latest Mousterian levels (MS1-MS2, associated with Neanderthals) at Riparo Bombrini (Liguria, Italy) to assess the changes over these three stratigraphic units vis a vis other information about site use. Combining GIS and quantitative methods allows the study of the spatial distribution of plotted finds and features in these levels, showing that Neandertals and Homo sapiens organized their living spaces in accordance with the duration of occupation, the occupation intensity, the tool assemblage and the faunal exploitation. Our results indicate that there is a logic behind the distribution of plotted finds and the use of the space, suggesting comparable cognitive capacities for both anatomically modern humans and Neanderthals. This contributes further data that undermines the notion of 'behavioral modernity' as a useful heuristic in human origins research. [ABSTRACT FROM AUTHOR]

The Indian Middle Palaeolithic has been recognized as crucial evidence for understanding the complex behavioural dynamics of hominins and is also seen as a behavioural marker of early Homo sapiens in the region. Recent research has pushed back the timeline of the Middle Palaeolithic to the Middle Pleistocene epoch, indicating a potential in-situ emergence from the earlier Late Acheulian culture. The long-lasting Middle Palaeolithic culture in India evolve over multiple glacial-interglacial cycle, showing signs of behavioural resilience to bigger climatic upheaval like ~74 ka Toba super-eruption. This has added to the complexity of our understanding of the Middle Palaeolithic in the region and emphasizes the need for further research. This study focuses upon the investigation of Middle Palaeolithic artefacts found in the Retlapalle area within the upper Gundlakamma river basin, Andhra Pradesh. The dating of the artefact-bearing layer was carried out using the p-IR-IRSL method, which revealed a burial age of 139±17 thousand years. The Retlapalle assemblage is characterized by a diverse range of Levallois core reductions, various retouched artefacts, with a dominance of pointed tools, and a few blade components. The study provides a valuable addition to the existing body of data concerning Palaeolithic sites dating back to the Middle Pleistocene, a period that remains relatively underexplored.

In the last few decades, the field of ancient DNA has taken a new direction towards using sedimentary ancient DNA (sedaDNA) for studying human and mammalian population dynamics as well as past ecosystems. However, the screening of numerous sediment samples from archaeological sites remains a time-consuming and costly endeavor, particularly when targeting hominin DNA. Here, we present a novel high-throughput method that facilitates the fast and efficient analysis of sediment samples by applying a pooled testing approach. This method combines multiple extracts, enabling early parallelization of laboratory procedures and effective aDNA screening. Pooled samples with detectable aDNA signals undergo detailed analysis, while empty pools are discarded. We have successfully applied our method to multiple sediment samples from Middle and Upper Paleolithic sites in Europe, Asia, and Africa. Notably, our results reveal that an aDNA signal remains discernible even when pooled with four negative samples. We also demonstrate that the DNA yield of double-stranded libraries increases significantly when reducing the extract input, potentially mitigating the effects of inhibition. By embracing this innovative approach, researchers can analyze large numbers of sediment samples for aDNA preservation, achieving significant cost reductions of up to 70% and reducing hands-on laboratory time to one-fifth.

A stratigraphic sequence from Ghar-e Boof, a cave site in Iran, covering a period of c. 80,000–30,000 BP and containing more than 20,000 seed and chaff remains, allows a detailed study of the use of annual seed species of Palaeolithic hunter-gatherer groups and its evolution under the influence of changing environmental conditions. Taxonomic changes in the archaeobotanical assemblage and the stable carbon isotope data of pistachio support a considerable change in environmental conditions over the sequence from MIS 5a to MIS 3. The exceptional dominance of wild ancestors of modern crop species, including glume wheat and large-seeded legumes from Middle Palaeolithic layers AH VI (OSL ranges 72–81 ka BP), coincides broadly with the transition from MIS 5a to MIS 4. With the beginning of MIS 4 these taxa are strongly reduced, corresponding with a strong decrease in global CO2 concentrations and in the Δ13C values of Pistacia khinjuk/atlantica from the site. Wild glume wheat completely disappears after Middle Palaeolithic AH Vb and never reappears at the site. We hypothesize that the Middle Palaeolithic niche that allowed the harvesting and consumption of wild cereals and legumes ended with a destabilization of the vegetation in early MIS 4.

In order to gain better understanding of the Neanderthals' subsistence exploitation of marine crustaceans, this work presents evidence on the consumption of brown crabs using experimentation following-up from the archaeological evidence recovered from the 2010-2013 excavation of Gruta da Figueira Brava (Portugal). Amongst the aquatic fauna from occupation phase FB4, which dates to MIS-5b, brown crabs (Cancer pagurus) are numerous. The average carapace width estimated from their remains is 16 cm, and skeletal part analysis reveals the introduction of complete animals and their on-site processing. Due to the lack of a referential corpus for the interpretation of archaeological crab taphonomy, we experimented with the processing of two raw, two boiled, and two roasted brown crabs. We found that manual processing of large adult Cancer pagurus is only possible for the disarticulation of the walking legs, and the separation of the claws. Experimental results indicate that archaeological crabs were roasted, which weakened the shell and facilitated breaking it open. Though it is also possible to manually disarticulate the fingers, most times it requires a small hammerstone. Impact scars and longitudinal fractures bear witness to the use of such tools to access the meatier parts of both the propodus and the dactylopodus. [ABSTRACT FROM AUTHOR]

Lithic raw material properties are often invoked to explain the presence, absence, form, or ontogeny of Paleolithic stone tools. Here, we explore whether the frequency of the Middle Paleolithic Nubian core form and core‐reduction systems co‐varies with toolstone quality in two neighboring regions in Oman: the southern region of Nejd, Dhofar, and the south‐central region of Duqm, Al Wusta. Specifically, we predicted that if raw material differences were influencing the distribution of Nubian cores, the chert would be of higher quality in the southern region, where Nubian cores were frequent, and of lower quality in the south‐central region, where they were scarce. We tested this prediction by collecting 124 chert samples from 22 outcrops and then quantitatively assessed two geochemical variables that are widely thought to influence knapping: impurity amount and silica content. We also examined the mineralogical composition, and the crystallite size and lattice strain for quartz (crystalline α‐SiO2) of representative chert samples. Our results suggest that the cherts in the two regions are similar, which is not consistent with the hypothesis that lithic raw material quality contributed to Nubian core spatial distribution in Oman. We discuss potential alternative hypotheses to explain Nubian core geographic patterning, and provisionally suggest that the scarcity of Nubian cores in south‐central Oman may be due to a concomitant scarcity of toolmakers, given a lack of water availability.

A longstanding debate concerns the function of carinated elements in both, the Levantine, and European Aurignacian. The present study aims to contribute to this topic with the evaluation of the carinated assemblage from layer D in Hayonim Cave, Western Galilee, Israel, one of the type sites of the Levantine Aurignacian. An operational chain reconstruction with an attribute analysis is paired with a typological approach to the preparation and maintenance products based on artefacts defined as West European Aurignacian. The results of this study are investigated with multivariate statistics offering a methodological contribution. The data is subjected to a transformation into a distance matrix using the Gower distance and tested with the adonis-algorithm for significance. The results clearly indicate that the carinated items in Hayonim Cave did fully or partially function as cores. They are accompanied by diagnostic preparation- and- maintenance products known from the literature e.g. Thèmes bladelets. The statistical analysis indicates only a minor correlation with stratigraphy yet supports the techno-typological criteria applied for defining artefact categories (cores, debitage, tools), as well as the proposed differentiation of carinated 'core' types. The non-carinated cores in Hayonim Cave are characterised by a high variability in typology and reduction concepts. A curious similarity to the Levallois-concept is observed on some of the flake cores. It is therefore suggested that the frequent recycling of Middle Palaeolithic artefacts in the Levantine Aurignacian might have given the Aurignacian flint-knappers the opportunity to study the Levallois concept and apply an approximation of it in their own core reduction strategies. The notion that Palaeolithic flint-knappers actively observed former technological systems through the discarded artefacts directly opens up a new trajectory for the understanding of lithic reduction concept permanence. The conceptual diversification and variability in Hayonim Cave D indicate a highly dynamic period in the Levantine Upper Palaeolithic which increased the adaptive potential and promoted a rapid cultural change.

The Rocourt Tephra (RT) is a widespread stratigraphic marker distributed in Germany, Belgium, and the Netherlands, where it is used for stratigraphic correlations, dating of host sediments and of Middle Palaeolithic archaeological assemblages, sometimes including Neandertal remains. Its age is estimated between 78 and 80 ka. This tephra has been linked to the West Eifel Volcanic Field in Germany, but its corresponding source volcano is unknown. Such a discovery would make it possible to confirm or challenge the age of the tephra, because this source volcano could be dated by various methods. It would also be possible to know the composition of the magma, which cannot be determined from the altered clasts of the tephra, as well as the original mineralogical composition, thereby strengthening the validity of the marker by providing more distinctive data. Two Eifel monogenic volcanoes have been cited as potential sources, the Dreiser Weiher and the Pulvermaar, due to their large sizes and broadly similar compositions. A study of the tephra layers from these volcanoes was carried out to compare their mineral compositions with that of the Rocourt Tephra. Based on new analytical data on the composition and magmatic trends of pyroxenes, it is concluded that neither of the two volcanoes can be the source of the RT. [ABSTRACT FROM AUTHOR]

The archaeology of inland waters is a relatively recent scientific branch in the Czech Republic. The insufficient state of research affected the first attempts at extensive documentation and evaluation of river finds and has caused many challenges. Results of a pilot study aimed at processing and evaluating river finds dated from the Palaeolithic to the Early Middle Ages discovered in the two largest Moravian rivers, the Morava and the Thaya, endeavoured to identify and describe these issues and improve the protection of underwater cultural heritage in the respective rivers.

Interpretations of Late Pleistocene hominin adaptative capacities by archaeologists have focused heavily on their exploitation of certain prey and documented contemporary behaviours for these species. However, we cannot assume that animal prey-taxa ecology and ethology were the same in the past as in the present, or were constant over archaeological timescales. Sequential isotope analysis of herbivore teeth has emerged as a particularly powerful method of directly reconstructing diet, ecology and mobility patterns on sub-annual scales. Here, we apply 87Sr/86Sr isotope analysis, in combination with δ18O and δ13C isotope analysis, to sequentially sampled tooth enamel of prevalent herbivore species that populated Europe during the Last Glacial Period, including Rangifer tarandus, Equus sp. and Mammuthus primigenius. Our samples come from two open-air archaeological sites in Central Germany, Königsaue and Breitenbach, associated with Middle Palaeolithic and early Upper Palaeolithic cultures, respectively. We identify potential inter- and intra-species differences in range size and movement through time, contextualised through insights into diet and the wider environment. However, homogeneous bioavailable 87Sr/86Sr across large parts of the study region prevented the identification of specific migration routes. Finally, we discuss the possible influence of large-herbivore behaviour on hominin hunting decisions at the two sites. Using multi-isotope analysis of tooth enamel of reindeer, equids and mammoth from the archaeological sites of Königsaue and Breitenbach, the authors identify shifts in ranging behaviour of these hominin prey species during the Last Glacial Period in Central Germany.

The Xiachuan site (35°26′22″N, 112°00′43″E) in Shanxi Province, northern China is an important Middle and Upper Paleolithic site, which contains four stages of development: the Middle Paleolithic culture, the initial and early Upper Paleolithic culture, the middle Upper Paleolithic culture and the late Upper Paleolithic culture. To establish the chronology framework for the site, a pedo-stratigraphic sequence at the QX2017T1 survey section of Fuyihegeliang Locality (Loc. FYH) was dated using blue-stimulated optically stimulated luminescence (OSL) on fine-grained quartz and post-infrared infrared stimulated luminescence (post-IR IRSL or pIRIR) on fine-grained polymineral. The quartz OSL ages of the Upper Paleolithic culture layer are between 21.4 ± 1.6 and 42.2 ± 3.0 ka, which is consistent with the calibrated 14C ages. The Middle Paleolithic culture layer is dated to from 118.2 ± 8.5 to 128.3 ± 9.5 ka using the polymineral pIRIR 100, 290 protocol. These new results allow us to put the main part of the Upper Paleolithic culture layer in the late Marine Isotope Stage (MIS) 3 and the early MIS 2, with the Middle Paleolithic culture layer corresponding to the early MIS 5. A gap of nearly 70 ka is observed between the two cultural layers, which is larger than previously expected. The presence of early hominins in the Xiachuan site during MIS 2 and MIS 3 as well as in early interglacial MIS 5 reflects their ability of adapting to variable environments. [ABSTRACT FROM AUTHOR]

Northeast China played an irreplaceable role in population migrations and cultural exchanges in East Asia during the Paleolithic. This paper collected 182 archaeological sites to analyse the characteristics of spatial-temporal variations of Paleolithic human activities in Northeast China, and explored the driving mechanisms behind these variations in combination with the paleoenvironmental and archaeological studies. During the Lower Paleolithic, constrained by the relatively cold-dry climate and blocked by the Songnen paleo-lake basin, the population was sparse and distributed only near 40° N at the southern end of Northeast China. Upon entering the Middle Paleolithic, as humans developed greater tolerance to cold climates and adopted more sophisticated survival strategies with the application of small lithic tools, their numbers increased and geographical distribution expanded northward to 45° N at the central region of Northeast China. The Upper Paleolithic saw a considerable increase in population and expansion across almost all of Northeast China except for the eastern Inner Mongolia Plateau. We speculated that 50 ka and 30 ka BP were two key points, both of which may be associated with a significant increase in the frequency of migrations and communications among humans, and the widespread popularity of highly mobile microblade technology, respectively. In addition, the environmental analysis of archaeological sites revealed a continuous spread of Paleolithic humans to areas with higher elevations, steeper slopes, and lower temperatures. Meanwhile, they were becoming less reliant on water resources and were more widely conducting activities in open-air areas, showing that the environmental adaptability had been continuously improving over time. This study can provide a reference for the reconstruction of the migration history of early humans in East Asia, and is also of great significance for a comprehensive understanding of the evolutionary process of early human-environment interactions.

The Iranian Plateau and the Zagros Mountain chain, located at the crossroads of Africa and Eurasia, occupy a critical geographical position in out-of-Africa scenarios, sitting astride a major dispersal corridor into southern and central Asia. Yet, the region's role in human population expansions remains under-investigated. Here, we present findings from new excavations at Pebdeh Cave, a site located in the southern zone of the Zagros Mountains. Pebdeh contained a well-defined layer dating to -42-40,000 years ago (ka), with Levallois elements alongside laminar reduction. This transitional feature in the Zagros was not dated and recorded before, and, given its similarity to Western and Central Asian industries with respect to chronology and technological features, we define it here as the Zagros Initial Upper Paleolithic (IUP). Although Late Middle Paleolithic and Early Upper Paleolithic technologies have been identified in the Zagros in the time period ranging between 50 and 40 ka, suggesting the presence of Neanderthals and modern humans in the mountainous region, the overall abrupt and constrained chronology of the IUP at Pebdeh, together with the penecontemporaneous appearance of other Upper Paleolithic sites in the Zagros Mountains, is compatible with a population expansion of Homo sapiens rather than an autochthonous development.

The calcaneal morphology changed considerably during human evolution to enable efficient bipedal locomotion. However, little information exists regarding its adaptation to changes in habitual activities following the transition to a sedentary lifestyle. We aimed to examine changes in calcaneal morphology during the Pleistocene-Holocene Levant in light of sexual dimorphism. We studied three archaic Homo sapiens calcanei dated to the Middle and Upper Paleolithic, 23 Natufian hunter-gatherers, 12 Pre-Pottery Neolithic early farmers, and 31 Chalcolithic farmers. The calcanei were scanned via a surface scanner and measured, and bone proportions were calculated. Measurements included the height, length, and width of various calcaneal elements. The sex of each individual was determined using methods based on calcaneal morphology. The validity of these methods was tested in those individuals who had the pelvis (92.3% agreement rate). Accordingly, the sample included 59.4% males and 40.6% females. Most calcaneal indices were sex-independent, except for the relative width, relative anterior length, and the cuboid index. Temporal trends between the Natufian and Chalcolithic periods were more pronounced among males than females. While in the proximal calcaneus, the temporal trend was similar between males and females, it differed in the distal part and articular facets. The calcanei of archaic H. sapiens exceeded the average of the Natufian hunter-gatherer for most variables, though the trend varied. To conclude, males and females were affected differently by the changing environment. The calcanei of archaic H. sapiens were better adapted for activity involving high mobility, independent of sex. During the transition to a sedentary way of life, different factors probably designed the male and female calcaneus. These could include factors related to the sexual division of labor, adaptation to lengthy standing, and changes in footwear. [ABSTRACT FROM AUTHOR]

Ancient adhesives used in multicomponent tools may be among our best material evidences of cultural evolution and cognitive processes in early humans. African Homo sapiens is known to have made compound adhesives from naturally sticky substances and ochre, a technical behavior proposed to mark the advent of elaborate cognitive processes in our species. Foragers of the European Middle Paleolithic also used glues, but evidence of ochre-based compound adhesives is unknown. Here, we present evidence of this kind. Bitumen was mixed with high loads of goethite ochre to make compound adhesives at the type-site of the Mousterian, Le Moustier (France). Ochre loads were so high that they lowered the adhesive's performance in classical hafting situations where stone implements are glued to handles. However, when used as handheld grips on cutting or scraping tools, a behavior known from Neanderthals, high-ochre adhesives present a real benefit, improving their solidity and rigidity. Our findings help understand the implications of Pleistocene adhesive making. [ABSTRACT FROM AUTHOR]

In the present work, more than one hundred and thirty lithic artefacts rediscovered in several archaeological sites dating from the Upper Palaeolithic to the Middle Ages from Calabria (Southern Italy) were petroarchaeometrically characterised through minimally invasive techniques. In more detail, 110 specimens were found in the Grotta della Monaca site (Sant'Agata di Esaro), and the other 23 belong to a collection kept in the Museo Nazionale Preistorico ed Etnografico "Luigi Pigorini" (Roma), coming from several localities (Longobucco, Spezzano della Sila, Cicala, Gimigliano, Roccaforte del Greco, and Bova). For preservation needs, 2 small axes in polished stone and 2 obsidians collected from Grotta della Monaca were analysed by absolutely non-destructive techniques. Optical and electron microscopic investigations, sometimes integrated with wavelength-dispersive X-ray fluorescence spectroscopy and X-ray diffraction spectrometry, allowed us to ascertain that the source area of all the lithic tools was in Calabria, except for obsidians, which come from the island of Lipari (Messina, Southern Italy). For a small number of particularly favourable cases, it was possible to define with great precision the outcrop area of the used rocks given their textural and mineralogical features. The specific source area contained a pickaxe originating from Cetraro–Fuscaldo metabasalt (lawsonite–albite facies) outcrops and two small axes in polished stone, one derived from migmatitic metapelites from Palmi and the other from meta-ultramafic rocks from Curinga. The choice of the used lithologies, harder or softer, had to be linked to the use that humans had to make of the lithic artefacts. [ABSTRACT FROM AUTHOR]

Mani peninsula is considered an important region for the Palaeolithic research of Greece. A considerable number of sites have been excavated to date, containing deposits with cultural remains from the Middle Palaeolithic, the Upper Palaeolithic, and the Neolithic period. Melitzia Cave is a cave locality filled with Upper Pleistocene deposits, yielding in the upper stratigraphic units fossil remains of numerous large mammals and small vertebrates along with cultural remains, indicating that the cave was inhabited by both humans and carnivores. The layers date to the Upper Pleistocene, and more specifically between 46,448–44,553 BP and 11,150–10,680 BP. The present study focuses on the recovered carnivore assemblage of Melitzia Cave, which has revealed the presence of Crocuta spelaea, Vulpes vulpes, Felis silvestris, Meles meles, Mustela nivalis, Martes sp., ?Ursus sp., and Carnivora indet., described in detail herein. This species composition is typical for the late Pleistocene of Southeastern Europe. [ABSTRACT FROM AUTHOR]

Bawa Yawan Rock Shelter is one of the critical Palaeolithic sites discovered recently in the Central Zagros in Western Iran. The site exhibits a rich assemblage from the Middle Palaeolithic (Zagros Mousterian) to the Epipalaeolithic, and it discloses one Neanderthal canine tooth. The site stands out as one of the handfuls of Palaeolithic sites in the Central Zagros that contain human remains. Therefore, establishing a reliable chronology revealing the temporal period in which Neanderthals inhabited the region plays a significant role in our understanding of the human past in the region. We employed luminescence dating in combination with Bayesian modelling to improve the precision of the estimated ages. Our results indicate that the Middle Palaeolithic assemblages unearthed from geological layers GH3 to GH5 in the site fall in the [58–80] ka time frame (68% credible interval). More importantly, the Bayesian age for the layer containing the Neanderthal remains exhibited [65–71] ka (68%). This age contradicts the previous 14C-based chronology. We argue that it is likely that the 14C dates underestimate the timing of the Middle Palaeolithic industries at Bawa Yawan. Furthermore, our study reveals the first luminescence age for the Epipalaeolithic in the Central Zagros, which is dated to [13–15] ka (68%). [ABSTRACT FROM AUTHOR]

This study presents the results of the Pleistocene Period survey conducted in Divriği, Kangal, Gürün and Altınyayla Districts of Sivas Province between 2016-2019. The aim of the study was to identify chipped stone tools, caves, rock shelters and raw material resources indicating the presence of Paleolithic humans in Sivas and to add the findings to the Paleolithic stratigraphy of Turkey. "Pedestrian survey method" was used in the research. The chipped stone remains were firstly divided according to Paleolithic ages and technologicaltypological descriptions of the chipped stone remains were made. During the survey, 16 Paleolithic sites were identified and 236 lithics were identified. No caves or rock shelters containing Paleolithic deposits were found, but Divriği, Kangal and Gürün are rich in volcanic rocks and flint. Technological and typological analyses of the stone tools revealed the presence of a Lower Palaeolithic culture in Divriği using volcanic rocks, similar to the Mode 1 industry, and Middle Palaeolithic and Late Upper Palaeolithic (perhaps Epipaleolithic) cultures in Kangal, Gürün and Altınyayla, where flint was the preferred raw material. The Middle Palaeolithic culture of Sivas is more similar to the Middle Palaeolithic finds from Karain Cave than Hatay. Since the finds were not in situ, radiometric dating was not possible. This study is one of the rare Palaeolithic archaeological investigations conducted in the region and demonstrates that humans were able to live at high altitudes during the Pleistocene, that Sivas was an important transition zone during the Pleistocene, and that at least two different human species must have lived in the region.

The discovery of a very distinct and rather isolated group of the Middle to Early Upper Palaeolithic sites around the Svitava River to the north of Brno has been made very late. This study focuses on the new collections assembled by Petr Gadas and comprising all groups of artefacts. The Horky Hill above Bořitov was the site of one of the biggest centers of the Middle Palaeolithic Micoquian. Despite the presence of one of the Cretaceous spongolite (i.e., the most numerous raw material) outcrops directly on the hillside this was not a workshop site; the quantity of retouched tools even outnumbers the contents of all the Middle Palaeolithic levels in the Kůlna Cave altogether. Both sites fundamentally differ in a much stronger representation of prismatic cores, blades, and characteristic Upper Palaeolithic types at Bořitov V; the dominant hill certainly draw attention even after the demise of the Micoquian. However, the degree of patination is identical in all types of cores and tools. A part of progressive elements in the sphere of technology (blades and blade cores) and typology (end scrapers, often with pronounced side retouch) can occur even in the late phase of the Micoquian, perhaps the main period of occupation of the site.

The present study seeks to better understand the coupling of social and biophysical systems during the late Pleistocene and Holocene, a period characterized by changing interglacial conditions as well as human population expansion and intensified ecosystem management. The approach consists of a combination of patch-based archaeological survey methods, sediment column sampling for paleoenvironmental data, geospatial analysis, and machine learning for chronological unmixing, allowing the systematic evaluation of the distribution and intensity of prehistoric land use in the study area of eastern Mediterranean Iberia. Occupational and Land Use Intensity maps developed from continuous distributions of surface artifacts as well as a summed probability density curve developed from 14C dates indicate low but steady human presence in the study area during the Middle Paleolithic and Upper Paleolithic with a marked decrease of human presence across the Pleistocene/Holocene boundary. The Early (and Middle) Neolithic saw the most ubiquitous and intensive occupation of the study area followed by a significant decline during the Late Neolithic/Chalcolithic. The charcoal analysis also supports this pattern. Early Neolithic farming strategies may not have been damaging initially during the climatic regime of the Early Holocene but exacerbated the impacts of higher temperatures and summer droughts, with a loss of the most productive farmland, seen at the onset of the Late Neolithic. Similar boom-bust population trends have been documented throughout Europe during these same time spans and may indicate a recursive interaction or "coupling" between global and regional climate events and human land use strategies.

The chronology and hominin association of the South Asian Middle Palaeolithic have attracted much attention in the last few decades. The emergence of Middle Palaeolithic culture in the region has been debated between the local origins (behavioural change) model based on an early date around 380 ka and the diffusion (biological change) model based on Homo sapiens dispersals from Africa around 120-80 ka. The latter has more consensus, whereas the former requires a more robust chronological framework to attribute the emergence of the Middle Palaeolithic to behavioural changes. In the absence of hominin remains, the presence of Middle Palaeolithic technological trajectories are frequently used as behavioural markers of Homo sapiens. Homo sapiens fossil remains from the regions between Africa and South Asia dated to ~ 200 ka presents more convincing support for the latter model. Here we present contextual, chronological and technological analysis of Middle Palaeolithic assemblages dated to 52 ka from Motravulapadu, Andhra Pradesh, India. Morphometrical analysis of the lithic assemblage indicates diverse Levallois core reductions were practised at the site at the onset of MIS 3. Further this evidence highlights the significance of MIS 3 cultural diversity in South Asia, likely related to changing population dynamics, cultural drift, and the highly variable climatic context of MIS 3.

Europe is characterized by an uneven record of Middle Paleolithic occupations. Specifically, large parts of southeastern Europe display markedly lower site densities and less intensive evidence of human presence than is found elsewhere; this has often resulted in the exclusion of the Balkans from debates related to Pleistocene human adaptation. The discrepancy stems either from the lower population densities of southeastern Europe or an imbalance in research across Europe. Additionally, our understanding of Balkan Middle Paleolithic stone tool industries suffers from the use of Mousterian labels defined when Bordian typology was the chief method of lithic analysis. Industrial facies then defined and still in use include Balkan Charentian, Levallois Mousterian, Micromousterian, Denticulate Mousterian; their relation with the rest of the Eurasian record was and remains unclear. This paper sets aside the issue of scarcity of Pleistocene occupations and tries to address Neanderthal biogeography, and variations in Neanderthal technological behavior and subsistence, based on the available record. It reviews the current Middle Paleolithic record in the Balkans, presents the apparent temporal and spatial trends, and presents the provisional biogeography of hominins, including scenarios for the demise of Neanderthals at or soon after the arrival of modern humans in Europe. The paper ends with a discussion of perspectives for future research arising from this analysis of the available record and proposes some hypotheses regarding the role of the Balkans in the overall context of the occupational history of western Eurasia in the Middle/Late Pleistocene.

We examined lithic artifacts from the late Neanderthal site Sesselfelsgrotte (Bavaria, Germany) in order to evaluate the possibility of fire use and intentional flint heat treatment performed by late Neanderthals. We analyzed 1113 flint pieces from the G-layer complex (~60 to 45 kya; Micoquian) and 946 from the lower-layer complex (~115 to 70 kya; Mousterian). Based on macroscopic traits associated with the exposure of flint to heat and fire, we assigned artifacts to one of three groups: burnt, unburnt, and possibly intentionally heated. Our results show that while both complexes demonstrate the clear presence of fire, fire is more common in the younger G-layer complex. Moreover, possibly intentionally heated pieces are significantly more frequent in the G-layer complex, especially among the tools and specifically among side scrapers, suggesting a link between heat treatment and the production of these tools, most probably due to their functional and cultural significance. We therefore suggest that the flint in the G-layer complex of Sesselfelsgrotte underwent intentional heat treatment. The proportions of burnt flint artifacts in both complexes suggest an intensification in fire use at the site over time, while the appearance of possibly intentionally heated artifacts in the G-layer complex suggests the development of this advanced pyrotechnology by Neanderthals sometime between these two timeframes. Our results are supported by sedimentological and faunal data. We view these results as further indication of the advanced cognitive and technological capabilities of Neanderthals, which did not fall short of those of early modern humans. [ABSTRACT FROM AUTHOR]

Ez a tanulmány hozzájárul a barlangi hiéna szerepének megértéséhez az érdi állatcsontmaradványok eredete és felhalmozódási folyamata kapcsán, amelyben a neandervölgyi emberek tevékenysége is világosan kimutatható. Megkísérel betekintést nyújtani e ragadozó pusztító potenciáljába Érd és a magyarországi lelőhelyek korpuszában. This research is helping to understand the role of the hyena in the origin and accumulation history of the site of Érd's bone assemblage, in which the role of Neanderthals is also clearly highlighted. It attempts to provide an insight into the destructive potential of this carnivore at Érd and in the corpus of Hungarian sites. [ABSTRACT FROM AUTHOR]

During the Upper Paleolithic, lions become an important theme in Paleolithic art and are more frequent in anthropogenic faunal assemblages. However, the relationship between hominins and lions in earlier periods is poorly known and primarily interpreted as interspecies competition. Here we present new evidence for Neanderthal-cave lion interactions during the Middle Paleolithic. We report new evidence of hunting lesions on the 48,000 old cave lion skeleton found at Siegsdorf (Germany) that attest to the earliest direct instance of a large predator kill in human history. A comparative analysis of a partial puncture to a rib suggests that the fatal stab was delivered with a wooden thrusting spear. We also present the discovery of distal lion phalanges at least 190,000 old from Einhornhöhle (Germany), representing the earliest example of the use of cave lion skin by Neanderthals in Central Europe. Our study provides novel evidence on a new dimension of Neanderthal behavioral complexity. [ABSTRACT FROM AUTHOR]

Here we present stable carbon, nitrogen and sulfur isotope ratios of collagen extracted from Rangifer, Equus and Bison bone (n = 128) from different stratigraphic levels at the chronologically well-constrained Middle and Upper Palaeolithic site of Les Cottés, France. Samples were taken from five phases of site use (US08, US06, US04 [upper and lower], and US02; ~ 45.8–35.3 ka cal BP) to explore the dietary and spatial palaeoecology of these ungulate species during MIS 3, and the contemporary climate. Temporal trends in δ15N values of all species broadly align with other climatic indicators at the site and the lowest values in US04 correspond to the Heinrich 4 cooling event, reflecting changes in the composition of soil/plant nitrogen at this time. Rangifer collagen is 13C-enriched compared to the other species throughout, consistent with lichen consumption. However, this isotopic niche partitioning between Rangifer and Equus/Bison is most extensive during US04, indicating plasticity in reindeer feeding behaviour, and potentially overall increased lichen biomass during this cooler/more arid phase. Rangifer δ34S values are consistently lower than Equus and Bison, which could be indicative of their more extensive spatial ranges incorporating greater inland areas. Equus and Bison demonstrate a significant decrease in δ34S values through time, which may be linked to contemporary climatic decline. [ABSTRACT FROM AUTHOR]

The evolution of the hominin hand has been widely linked to the use and production of flaked stone tool technologies. After the earliest handheld flake tools emerged, shifts in hominin hand anatomy allowing for greater force during precision gripping and ease when manipulating objects in-hand are observed in the fossil record. Previous research has demonstrated how biometric traits, such as hand and digit lengths and precision grip strength, impact functional performance and ergonomic relationships when using flake and core technologies. These studies are consistent with the idea that evolutionary selective pressures would have favoured individuals better able to efficiently and effectively produce and use flaked stone tools. After the advent of composite technologies during the Middle Stone Age and Middle Palaeolithic, fossil evidence reveals differences in hand anatomy between populations, but there is minimal evidence for an increase in precision gripping capabilities. Furthermore, there is little research investigating the selective pressures, if any, impacting manual anatomy after the introduction of hafted composite stone technologies ('handles'). Here we investigated the possible influence of tool-user biometric variation on the functional performance of 420 hafted Clovis knife replicas. Our results suggest there to be no statistical relationships between biometric variables and cutting performance. Therefore, we argue that the advent of hafted stone technologies may have acted as a 'performance equaliser' within populations and removed (or reduced) selective pressures favouring forceful precision gripping capabilities, which in turn could have increased the relative importance of cultural evolutionary selective pressures in the determination of a stone tool's performance.

Although Middle Paleolithic (MP) hominin diets consisted mainly of ungulates, increasing evidence demonstrates that hominins at least occasionally consumed tortoises, birds, leporids, fish, and carnivores. Until now, the MP zooarchaeological record in the Zagros Mountains has been almost exclusively restricted to ungulates. The narrow range of hominin prey may reflect socioeconomic decisions and/or environmental constraints, but could also result from a research bias favoring the study of large prey, since archaeologists have undertaken no systematic taphonomic analyses of small game or carnivores in the region. Here, we report on the first comprehensive taphonomic analysis of an MP faunal assemblage from Ghar-e Boof (∼ 81–45 kyr), a Late Pleistocene site in the southern Zagros of Iran. Anthropogenic bone surface modifications point to hominins as the main agent of accumulation. Hominins preyed primarily on ungulates, particularly wild goat. However, we also found evidence for MP hominin exploitation of carnivores and tortoises at the site. Although small game represents only a minor portion of the diet, our results suggest that the hunting behavior of MP hominins in the Zagros was more diverse than previously thought, similar to what we find elsewhere in Eurasia.

Bone retouchers are a technological appliance used to perfect lithic tools efficiently. They are most frequently found in Middle Palaeolithic contexts. In this paper, we present a group of bone retouchers from the Mousterian Level XV of the Sopeña rock shelter (Asturias, Spain). The bone part preferred was the middle part of the shaft of long bones: Most of them are on metacarpals, followed by metatarsals, femurs, and tibias. The most used animal species is adult red deer. These retouchers have either one, two, or three active areas, with a central disposition. The impact marks are close together; oval pits are common, as well as straight, sinuous, and irregular grooves. The surfaces on these marks appear pitted and scaled. There are indications that the bones employed were relatively fresh. The length, width, and thickness of those bone fragments seem to be the determining factor when choosing them to be used as retouchers in the process of finishing lithic tools. The formats documented in Sopeña Level XV are similar to those found in other Mousterian sites in Iberia, although there is a certain variability regarding their width. The Neanderthals of Sopeña acquired the raw material for these retouchers from the faunal remains generated in the process of butchering and eating the animals. These retouchers were used as implements to perfect lithic tools made mainly on quartzite, and they were used repeatedly and maybe for a long time. [ABSTRACT FROM AUTHOR]

The Abrigo de la Quebrada is a Middle Palaeolithic rockshelter located in the Rambla de Ahíllas in the Iberian Range (Valencia, Spain). Archaeological work began in 2007 and was completed in 2015, reaching the rockshelter substratum and uncovering a record that spans from MIS 5 to MIS 4/3. The data from the geoarchaeological and micromorphological study of the site allow us to deduce that it was formed by alluvial contributions from the ephemeral stream, in different subenvironments varying from channel/bar to floodplain facies. These alternate with debris from different displacement processes depending on the unit, such as solifluction–gelifluction, mass displacement, and diffuse runoff. In addition, collapse episodes of the overhanging rockshelter roof influenced the pedological evolution of the record, with implications for the archaeological levels, especially in Unit G (Level IV). From a paleoenvironmental point of view, a more contrasted variability is reflected in the upper units of the site (MIS 4/3), especially in Unit G (Level IV), which, based on data, suggests temperate conditions, and in Unit H (Levels III and II) indicate cold conditions. In contrast, the lower units (MIS 5) are generally temperate, with the exception of Unit C (Level VIIIa), which reflects a colder phase. [ABSTRACT FROM AUTHOR]

Open-air surface accumulations and scatters of material cultural remains often are perceived as less-reliable archaeological archives, where it is difficult to distinguish anthropogenic versus geogenic formation processes or to assess their specific effects on the integrity of archaeological records. Here we analyze the depositional histories of three Middle Paleolithic open-air sites in the Negev desert of Israel, combining archaeological and geomorphological methods to create a conceptual model of multi-scale effects on the archaeological remains. Relying on the long research history in archaeology and geomorphology in the Negev, we show that integration of archaeological and geomorphological methodologies provides nuanced insights to our understanding of the archaeological record. The links established between regional and local geomorphic processes and lithic taphonomy by applying such a multi-scale analysis further allow back-tracking environmental processes from flint taphonomic attributes. Placing each site within the range of regional and local processes of exposure and burial by using informed and critically evaluated data helps to create a robust regional archaeological data base. We suggest that our approach is useful in other arid zone contexts and may have implications for understanding Pleistocene population movements across such regions. [ABSTRACT FROM AUTHOR]

Gruta da Oliveira features a c. 13 m-thick infilling that includes a c. 6.5 m-thick archaeological deposit (the "Middle Palaeolithic sequence" complex), which Bayesian modelling of available dating results places in MIS 5a (layers 7–14) and MIS 5b (layers 15–25), c. 71,000–93,000 years ago. The accumulation primarily consists of sediment washed in from the slope through gravitational processes and surface dynamics. The coarse fraction derives from weathering of the cave's limestone bedrock. Tectonic activity and structural instability caused the erosional retreat of the scarp face, explaining the large, roof-collapsed rock masses found through the stratification. The changes in deposition and diagenesis observed across the archaeological sequence are minor and primarily controlled by local factors and the impact of humans and other biological agents. Pulses of stadial accumulation—reflected in the composition of the assemblages of hunted ungulates, mostly open-country and rocky terrain taxa (rhino, horse, ibex)—alternate with interstadial hiatuses—during which carbonate crusts and flowstone formed. Humans were active at the cave throughout, but occupation was intermittent, which allowed for limited usage by carnivores when people visited less frequently. During the accumulation of layers 15–25 (c. 85,000–93,000 years ago), the carnivore guild was dominated by wolf and lion, while brown bear and lynx predominate in layers 7–14 (c. 71,000–78,000 years ago). In the excavated areas, conditions for residential use were optimal during the accumulation of layers 20–22 (c. 90,000–92,000 years ago) and 14 (c. 76,000–78,000 years ago), which yielded dense, hearth-focused scatters of stone tools and burnt bones. The latter are ubiquitous, adding to the growing body of evidence that Middle Palaeolithic Neandertals used fire in regular, consistent manner. The patterns of site usage revealed at Gruta da Oliveira are no different from those observed 50,000 years later in comparable early Upper Palaeolithic and Solutrean cave sites of central Portugal.

In anthropological studies, one of the most important research problems is where the human species first appeared and their distribution areas. There is thousands of evidence that the earliest human species originated in Africa and then spread in waves to other continents. Due to the location of Anatolia between the continents of Africa, Asia, and Europe, it is of great importance in terms of researching this subject. Excavations have been carried out since 2017 in the İnkaya Cave, which was discovered during the survey conducted to determine the habitat and distribution areas of human species in the northwestern part of our country. In this study, evaluations are made about the surveys carried out during seven seasons and the excavations carried out during six seasons in Çanakkale. In the rocky system of İnkaya Cave, which was formed by volcanic activities in the Late Oligocene-Early Miocene period, cultural remains are belonging to people who lived for about 86 thousand years. Chipped stone tools made of flint, basalt, and andesite reflect the use of the cave in the Middle Paleolithic period. İnkaya Cave has the potential to explain the possible migrations of fossil people who lived during the glacial periods prevailing in the northern hemisphere during the Paleolithic and preferred relatively more suitable valley shelters between Anatolia and the Balkans.

Prehistoric projectile weapons are crucial for understanding the hunting behavior, survival strategies, and subsistence patterns of prehistoric humans. Arrowheads were the primary prehistoric projectile weapon, and here we review the spatio-temporal distribution and changes in the morphology, quantity, and materials composition of arrowheads in the northern regions of China from the Middle and Upper Paleolithic periods to the Bronze Age, together with the factors that influenced these changes. The results reveal that primitive stone arrowheads appeared sporadically in the Middle Paleolithic period. Additionally, the "broad spectrum revolution" and microblade technology during the Upper Paleolithic promoted the regional-scale diffusion of broad and thick stone arrowheads in northern China. During the Neolithic period, relatively narrow and thin stone and bone arrowheads spread rapidly across the entire Yellow River Basin and most of northeastern China. The dominance of these two types of arrowheads alternated, during the period of 7000–5000 yr BP, the number of arrowheads peaked, possibly closely related to changes in the role of hunting (fishing and hunting) and gathering in the subsistence economy, human population size, and the emergence and development of a grinding technology. During the Bronze Age, a significant number of bronze arrowheads appeared, and the total number of arrowheads increased again, and their distribution expanded to northwestern China. The emergence of a bronze smelting technology and inter-group conflicts may have been the primary factors influencing this trend. Our results demonstrate that arrowheads were always an essential component of prehistoric tool kits. Due to technological developments in subsistence strategies, the morphology, function, and popularity of arrowheads underwent substantial changes during different periods. Therefore, a comprehensive study of prehistoric arrowheads can help better understand the subsistence patterns and processes of economic and societal development of prehistoric humans.

The eruption of Toba ca. 75 ka was the largest volcanic eruptive event during the Quaternary, and evidence for this eruption is widespread in terrestrial sediment sequences in South Asia as primary and reworked distal ash deposits. Youngest Toba Tuff horizons (YTT) have been widely employed as isochrons to understand and link regional sediment sequences and the evidence for environmental and cultural change in the archaeological records preserved within them. We identify the YTT deposits at Retlapalle, Andhra Pradesh, India, and present the optical ages of the K-feldspar grains recovered from sediments immediately underlying and overlying the tephra horizon. We combine these results with particle size and magnetic susceptibility analyses to establish the depositional conditions of YTT, which indicate that accumulation and reworking ceased by ca. 64 ka. We explore the role of YTT deposits as an isochron for examining the effect of the 75 ka Toba super-eruption, highlighting the need for an independent chronological assessment of YTT before using it as a Late Pleistocene chronological marker in reconstructing South Asian paleo-landscapes and hominin adaptations. Further, our findings support the regional continuity of human occupations within South Asia, spanning the eruption of Toba and the enduring utility of Middle Paleolithic tools.

This paper examines the hypothesis that changes in hunting weapons during the Paleolithic were a direct response to a progressive decline in prey size. The study builds upon a unified hypothesis that explains Paleolithic human evolutionary and behavioral/cultural phenomena, including improved cognitive capabilities, as adaptations to mitigate declined energetic returns due to a decline in prey size. Five selected case studies in Africa and Europe were analyzed to test this hypothesis, focusing on the relative presence of megaherbivores (>1000 kg) in the transition between the Acheulean/Early Stone Age and the Middle Paleolithic/Middle Stone Age. The findings indicate a decline in megaherbivores' presence and biomass contribution in the studied transition period associated with the introduction of Levallois technology. We review the evolution of hunting weapons, including wooden-tipped and stone-tipped spears and bows and arrows. Analysis of tip size and breakage patterns indicate a reduction in point size over time, aligning with the declining prey size. We propose that changes in hunting weapons and strategies were driven by the practical and ontological incentives presented by the availability and size of prey. Developing smaller, more precise weapons required increased cognitive capacities, leading to the parallel evolution of human cognitive abilities. [ABSTRACT FROM AUTHOR]

Bone retouchers were part of the human toolkit since the Lower Palaeolithic. These tools are essential to the understanding of lithic technology and raw materials exploitation in cultural complexes associated with both Homo neanderthalensis and Homo sapiens. They are also considered to be among the oldest bone tools ever made. On account of their great morphological variability and the lack of any standardised shaping, bone retouchers are often classified as expedient tools rather than as a true bone industry. The present work proposes a new approach to the use-wear study of bone retouchers through the application of 3D imaging microscopy. The results show several advantages in the identification and description of retouch-induced use-wear. The comparison with current methodologies suggests the need to rethink approaches to this bone industry. Through a more in-depth technological and functional study procedure, bone retouchers can potentially play a crucial role in understanding the subsistence strategies of hominin groups throughout the Lower, Middle and Upper Palaeolithic.

Observation of high-resolution terrestrial palaeoecological series can decipher relationships between past climatic transitions, their effects on ecosystems and wildfire cyclicity. Here we present a new radiocarbon dated record from Lake Fimon (NE-Italy) covering the 60–27 ka interval. Palynological, charcoal fragments and sediment lithology analysis were carried out at centennial to sub-centennial resolutions. Identification of the best modern analogues for MIS 3 ecosystems further enabled to thoroughly reconstruct structural changes in the vegetation through time. This series also represents an "off-site" reference record for chronologically well-constrained Palaeolithic sites documenting Neanderthal and Homo sapiens occupations within the same region. Neanderthals lived in a mosaic of grasslands and woodlands, composed of a mixture of boreal and broad-leaved temperate trees analogous to those of the modern Central-Eastern Europe, the Southern Urals and central-southern Siberia. Dry and other grassland types expanded steadily from 44 to 43 ka and peaked between 42 and 39 ka, i.e., about the same time when Sapiens reached this region. This vegetation, which finds very few reliable modern analogues in the adopted Eurasian calibration set, led to the expansion of ecosystems able to sustain large herds of herbivores. During 39–27 ka, the landscape was covered by steppe, desert-steppe and open dry boreal forests similar to those of the modern Altai-Sayan region. Both Neanderthal and Sapiens lived in contexts of expanded fire-prone ecosystems modulated by the high-frequency climatic cycles of MIS 3. [ABSTRACT FROM AUTHOR]

During the summer of 2019, the Bacton to Walcott Coastal Management Scheme involved the emplacement on to the foreshore of 1.8 million cubic metres of sand and gravel dredged from the submerged sediments of the Palaeo‐Yare in the southern North Sea 11 km off Great Yarmouth. During the following 2‐year period, an active group of collectors identified Palaeolithic artefacts eroding from these sediments, including Levallois cores and flakes, and cordiform handaxes. In this paper, we present an analysis of the lithic artefacts, and consider the relationships between the different elements of the assemblage. We discuss its significance in the context of the Middle Palaeolithic record of northwest Europe and the light it shines on the human occupation of the submerged landscape of the southern North Sea during the later Middle Pleistocene. Interrogation of beach survey data shows the reworking of these sediments to the southeast towards Happisburgh where archaeologically significant exposures of the Cromer Forest‐bed Formation are located. The implications of the introduction of a Middle Palaeolithic assemblage to this stretch of the North Norfolk Coast are considered, highlighting the importance of continuing dialogue between researchers, local authorities and local communities for capturing information and monitoring this critical Palaeolithic resource.

To spatially characterize the palaeolakeshore environment at the archaeological kill site Schöningen 13 II‐4 of the Middle Pleistocene Reinsdorf sequence, in‐depth palynological, geochemical, aquatic microfossil and archaeological analyses were undertaken on sediment sections with an average thickness of about 15 cm, concordantly overlain by faunal remains, dominated by horse, from the unique 'Spear Horizon' layers of the 1995 excavation campaign. The data reveal a distinctive lake level drop, documented by the change from a carbonate‐rich lake marl to a carbonate‐free organic mud with increased carbon content and decreasing C/N, Si/Al, Si/K and Fe/Al ratios, indicating a higher pedogenic supply of organic matter and drier conditions at the site. Compared with older, similar transitional phases of lake level changes occurring within the Reinsdorf sequence, it is important that these youngest sediments are undisturbed, indicating continuous development. Ostracod and diatom analyses indicate a lowering water level with higher salinities and rich aquatic vegetation. Mesorheophilic ostracod species along with tychoplanktic diatom taxa point to flowing waters and turbulence at the lakeshore, presumably related to spring‐fed streams originating from nearby highlands. Palynological results reveal a very diverse zonal vegetation pattern around the palaeolakeshore considering an area of investigation of approximately 50 × 75 m and a tessellated type of regional vegetation during the formation of the archaeological horizons. On topographically lower elevated areas, birch groves and taxa favouring wet, marshy conditions such as Cyperaceae, indicative of terrestrialization, were predominating, while other stands of this transitional phase reveal a very dry, grass‐dominated steppe woodland favouring a rich wildlife with a striking number of megaherbivores. Our results suggest that the lithological differences of the 'Spear Horizon' layers containing the archaeological finds were due to their respective topographical situation and that the layers were deposited almost simultaneously during the beginning of the lake level drop. Human activities seem to have concentrated in sparsely vegetated areas along the palaeolakeshore, rather than in areas of adjacent denser birch swamp forest stands. [ABSTRACT FROM AUTHOR]

La Mina is one of three sites, along with Cueva Millán and La Ermita, located in the middle course of the Arlanza river. La Mina was excavated for the first time in 2006 and three test pits were carried out. In one of them, evidence of two Palaeolithic occupations was identified and several remains of woolly rhinoceros were recovered. Amino acid racemisation dating yielded an age of 52.5 ka BP, the earliest Upper Pleistocene date for Coelodonta antiquitatis on the Iberian Peninsula. This new record may have several implications for understanding the access routes to the Castilian Plateau, together with the definition of a new migratory wave of this species at the end of the Pleistocene. The location of La Mina on the Castilian Plateau may help researchers to complete the movements of this species through the Middle and Upper Palaeolithic on the Iberian Peninsula.

This research addresses the geomorphological connectivity existing amid the piedmont's karstic fillings (Sierra de Esparteros) and the Guadaíra and Guadalquivir Rivers' alluvial terraces (SW of Spain), spotted with vestiges of human activities (Middle Palaeolithic). This study includes the analysis of 20 geoarchaeological sites and 28 lithic assemblages, with a total of 13,233 lithic pieces. Techno-typological and use–wear (SEM) analyses were conducted on these artifacts. Depending on the raw materials and the provenance of these lithic industries, two groups of assemblages were identified: one made of quartzite from the north, and another made of flint from the south. Two main geochronological periods were established (OSL and U/Th): (1) a short duration (MIS6/MIS5) and (2) a long duration (MIS5/MIS3). Techno-typological analysis showed three sorts of activities: (a) the provision and distribution of raw materials, (b) knapping, and (c) other activities that imply the use of a lithic workshop (LW), along with the settlement characteristics of habitual or recurrent (HS), temporary (TS), and indeterminate (IN). This geoarchaeological connectivity is called the "hominid alluvial corridor" (HAC). The underlined features are the geomorphological units, the continuum alluvial series, the raw material of the lithic industries as an indicator of provenance and transportation throughout the alluvial system, and the use–wear analysis of the tool-kit to interpret the functionality of the pieces.
