This paper describes the faunal record from a late Holocene archaeological site located on the freshwater wetlands of the South Alligator River and compares it with that from the Adelaide River, in the Northern Territory. The information characterizes freshwater wetland resources and their use by Aboriginal people, providing a snapshot of life on the floodplains immediately prior to European contact. Although the two wetland systems appear similar, and extractive technology in the form of bone points is also similar, the faunal assemblages show that Aboriginal hunting strategies differed between the two areas. These differences can be explained by variations in regional topography and seasonality of site use.

The La Guillerma archaeological locality is located in the northeast sector of Buenos Aires province (Argentina). Two of its sites (LG1 and LG5), dated between ca. 1400- and 600-years BP, have a great amount of faunal remains including deer, rodents, fish and small birds that are subjected to taphonomic agents and processes (e.g., weathering, manganese, roots). Previous studies have shown osteophagic behaviour in different insects (e.g., Coleoptera, Blattodea). In this paper, we evaluate their incidence on La Guillerma faunal assemblage. We performed an analysis on marks that were identified in bone remains of various taxa and applied the criteria for identifying bone alteration by insects (i.e., by measuring each trace and comparing them with the types of insect marks described in the literature). Fifteen specimens (LG1 = 6 and LG5 = 9) exhibited different types of modifications (e.g., pits with striae in base, pits with emanating striae, striations) that are related to the action of insects. Although the proportion of affected bones is low in relation to the total sample, we highlight our study as the first detailed analysis of insect marks on archaeological bones from Argentina. We also emphasize the significance of addressing insect-produced modifications on Argentinean archaeological sites. [ABSTRACT FROM AUTHOR]

The paper deals with landscape and settlement development between ca. 300 BC and AD 600 in a defined area of the northern Czech Republic. Despite favourable natural conditions, human occupation of the area did not begin until the end of the first millennium BC. Natural soil and vegetation development therefore lasted longer than in the traditionally settled lowland areas. Initial settlement activity from the La Tène period caused substantial erosion of deforested luvisols and retisols, well-documented by an accumulation of eroded soil horizons in a local wetland. The erosion process continued for more than 500 years following the end of the La Tène settlement, despite the fact that archaeological research revealed no reliable evidence of occupation prior to the twelfth century AD. Pollen and sedimentary records from the wetland, however, clearly indicate the existence of settlement activity during the "archaeologically invisible" Roman and Migration periods. This case is not unique and underlines the importance of environmental analysis for the detection of settlement history, particularly during periods of poor archaeological visibility or in places that are difficult to research using standard archaeological methods. The change in conditions after the first deforestation and subsequent late prehistoric settlement triggered the degradation of the deforested luvisols and retisols and led to the diversification of the soil cover, which now also includes regosols, gleysols, and truncated luvisols and retisols.

In this paper we present and assess human isotopic data (δ13C and δ15N) available for Southern Chile. We analyze 24 cases from six different geographical zones, dated 200-1850 AD. This new information allows us to characterize individuals who had different subsistence patterns, social organization and historical trajectories, vis-a-vis phenomena like the adoption of ceramics (150 BC), cultigens (750-1000 AD) and the arrival of Europeans (1550 AD). This is complemented by a regional baseline of 45 archaeological faunal and plant resources. Based on our results, three dietary patterns can be identified over time (from 1000 to 1850 AD): one oriented towards marine resources, another towards C 3 plants and terrestrial protein, and the last focused on a mixed consumption of C 3 and C 4 plants, complemented by intake of terrestrial and marine protein. These cases show significant intra-zone consistency over time, and high inter-zone variability. This heterogeneous situation is evident even in synchronous individuals ascribed to the same cultural-historical unit or inhabiting the same geographical macro-zone (valley, coast, islands). It also contrasts with results from adjacent areas to Southern Chile. This highlights the complex diet variability that existed in societies which otherwise appear to be extremely alike in their archaeological record (burials, pottery) and ethnographic features (language, rituals).

This paper shows the preliminary results of the zooarchaeological analysis of Dupuy Rockshelter (La Toma, San Luis Province, Argentina). This rock shelter has evidence of Late Holocene (Last Millennium) human occupation dating from 340 ± 40 BP. Some species, including Lama guanicoe and Ozotoceros bezoarticus , were exploited and their bones were used as raw material to make instruments. The zooarchaeological analysis is complemented by geological and phytoarchaological evidence which indicates a humid environment during the Holocene and a mixed diet that included vegetables.

This paper presents a new palynological record from a 146 cm long finely laminated sediment core obtained in 2009 from the deep-water meromictic Lake Shira (54°30′38″N, 90°12″09′E; ca. 353 m a.s.l.) situated in the Khakassian steppe region of southern Siberia between the rivers Ob' and Yenisei. The area is rich in lakes and represents an exceptionally well preserved sequence of Bronze and Iron Age archeological cultures. Little is known about the changes in vegetation and climate of the region during the Holocene. The palynological analysis of the core allows us to partly fill up this gap in current knowledge. The record of pollen and non-pollen palynomorphs presented here covers the past 2450 year interval with an average resolution of 22 years. The results obtained support the interpretation that the late Holocene vegetation changes around Lake Shira are mainly associated with large-scale atmospheric circulation processes controlling the regional water balance rather than with human activities. An attempt to trace human impact in the pollen assemblages provides no clear evidence for anthropogenic activity, except for the last few decades since ca. 1955, though the region has a long history of mobile pastoralists. For explanation of decadal-scale changes in the regional vegetation cover, the Artemisia /Chenopodiaceae (A/C) pollen ratio proved to be a reliable indicator of effective moisture availability. Using available fossil and published instrumental data our study suggests a link between the North Atlantic warmer/colder temperatures and higher/lower atmospheric precipitation (or moisture availability) in southern Siberia at multi-decadal to centennial scales.

This paper summarizes and discusses the main results achieved over three decades of research on paleodemographic aspects of Late Holocene hunter-gatherers in Northwestern Santa Cruz (Argentina). Research has been guided by a model of regional settlement that proposes that, as a result of the progressive aridization process recorded in Patagonia during the Late Holocene, human groups would have reduced their residential mobility and concentrated their settlements in low altitude basins with water availability, such as Lake Cardiel and Lake Salitroso. Paleodemographic questions derived from the model relate to population regional continuity and dynamics and were tested using several lines of research at regional and local scales. The assessment of the chronological information and temporal trends of the archaeological record at the regional level allowed for a coarse grain paleodemographic approach, and acted as a mean to support hypotheses related to changes in mobility and land use strategies. Building on this, several lines of bioarchaeological evidence were used to address paleodemographic aspects of the model, including temporal, distributional, and compositional studies of the mortuary record, isotopic, morphometric and DNA analyses and the sex and age structure of the skeletal samples recovered in Lake Salitroso basin. Results point to a biological and cultural population continuity in the region during the Late Holocene. Also, a reduction in residential mobility would have favored a slight population growth of Lake Salitroso populations during the last millennium. [ABSTRACT FROM AUTHOR]

In this paper we evaluate the role of human strategies in the Andean Piedmont from northern Patagonia across the Holocene. Specifically, we present the analysis of the Early Holocene-Late Holocene archaeological record of Salamanca cave (Mendoza-Argentina). We identified technological changes that occurred during the Late Holocene and the implications of a human occupation hiatus in the Middle Holocene. We follow a multiproxy approach by the analysis of radiocarbon dates, archaeofaunal remains, ceramic, lithics and XRF obsidian sourcing. We also discuss a detailed stratigraphic sequence by geomorphological descriptions, the construction of a radiocarbon sequence model and summed probability distributions, compared with other archaeological sites in the region. We conclude that after the Middle Holocene archaeological hiatus, human populations grew while guanaco populations dropped. The imbalance between demography and resources boosted the incorporation of new technologies such as ceramics and the bow and arrow, allowing people to exploit lower-ranked resources.

Megalithic monuments are a distinctive archaeological feature of Saharan landscape, as indicated by different systematic research projects undertaken so far. Starting from a very low baseline of previous archaeological research, and as part of a comprehensive research programme focussed on northern Sahara, we launched in 2015 a territorial investigation of stone monuments of the pre-protohistory and early history of southern Tunisia. To do this, we selected a sample study area east and south-east of the Chott el Jérid depression (Kebili region) where to conduct field research. In this paper we present the research strategy adopted, planned to address some issues such as the poor state of preservation of the monuments or their uncertain chronology, also known from other parts of the Sahara. Our results, based on the combination of remote sensing analysis, field survey and selected excavations, highlight a dense occupation of this area of northern Sahara, where monumental buildings of possible funerary function tentatively trace back to the late pre-protohistory up to the roman age. The persistent use of the area across a long-time span corroborates its pivotal location in ancient trans-Saharan connection routes.

This paper presents a dataset collected and constructed as part of a PhD research project in Environmental Sciences. Applying a multidisciplinary approach that combines archaeological and geomorphological data, this project aimed to reconstruct the Late Holocene landscape evolution in the Central Po Plain (Italy). The dataset was collected digitising the information retrieved from various sources such as scientific literature, regional databases and terrain surveys. In particular, the geoarchaeological data consist of a record of 761 archaeological sites and a soil map reporting the different sediment types of the area. Natural and anthropogenic landscape features developed by human-environmental interplay are organised in paleochannels, watercourses and channelisation. This dataset represents one of the first open-access data collection available in Italy and can be reused by any researchers working in fluvial landscape studies.

El entierro Shag se ubica en la costa norte de la provincia de Santa Cruz, Patagonia argentina. Se trata de una estructura con morfología anular o de anillo, de aproximadamente 10 m de diámetro, conformada por rocas. La estructura fue alterada por pingüinos de Magallanes, quienes realizaron un pozo de nidificación y, como consecuencia, expusieron en superficie una serie de restos óseos humanos. Para la Patagonia no existen antecedentes de estructuras mortuorias similares a Shag. Se presenta una datación radiocarbónica, el plano de la estructura, determinaciones bioantropológicas, estudios de isótopos estables δ13C y δ15N, y análisis tafonómicos de los restos óseos. Se interpreta que el sitio corresponde a una estructura mortuoria de cazadores-recolectores datada en el Holoceno tardío. Los estudios isotópicos permiten inferir que el individuo analizado basó su dieta en recursos de ambientes marinos y terrestres. ENGLISH: The Shag burial is located in the Santa Cruz province along the northern coast of the Argentinian Patagonia. The Shag burial site is contained by a structure with annular or ring morphology made out of rocks and approximately 10 m in diameter. The structure was altered by Magellanic penguins that built a nesting well, exposing a series of human bone remains on the surface. There is no record of similar mortuary structures within Patagonia. This paper presents a number of data including absolute radiocarbon dates, the plan of the structure, bioanthropological determinations, stable isotope studies of δ13C and δ15N, and taphonomic analyses of the bone remains. The site is interpreted to as a hunter-gatherers mortuary structure dated to the Late Holocene. The isotopic studies on the individual allow us to infer a varied diet, in which both marine and terrestrial food products were consumed.

Archaeologists make inferences about past human behaviour based on patterned material residues in various depositional contexts, including existing landsurfaces. These deposits are generated by processes that may obscure patterns at some observational scales while highlighting others, and interpretive differences can arise from a lack of explicit models of deposit formation. Here, an exploratory agent-based model based on the concept of the palimpsest is used to examine the effects of episodic sediment transport on the visibility and preservation of surface archaeological deposits in a fluvial context. Outcomes from the model indicate that the compound influences of preservation and visibility are capable of transforming a static radiocarbon record into one of increasing intensity towards the present, while simultaneously displaying periodic chronological gaps – features that have been used in our Australian study area to argue for demographic change driven by social or environmental factors. To differentiate between interpretations, expectations derived from the model are assessed against a second proxy from the same study area: Optically Stimulated Luminescence dates from hearth stones in surface contexts. Results indicate that patterns in the chronometric proxies from the study area are more consistent with episodic geomorphic change than explanations invoking changes in the local organization of human activity.
