Meat consumption by early hominins is a hotly debated issue. A key question concerns their access to large mammal carcasses, including megafauna. Currently, the evidence of anthropic cut marks on proboscidean bones older than -or close to- 1.0 Ma are restricted to the archaeological sites of Dmanisi (Georgia), Olduvai (Tanzania), Gona (Ethiopia), Olorgesailie (Kenya) and La Boella (Spain). During an inspection of the almost complete carcass of Mammuthus meridionalis (FN3-5-MPS) from the Oldowan site of Fuente Nueva 3 (Orce, Spain, c. 1.2 Ma), a few traces compatible with human-made cut marks and carnivore tooth marks were found. From this finding and previous interpretations the following questions arise: When and under what conditions was FN3-5-MPS deposited? What is the nature of the marks found on the surface of the bones of this mammoth? To answer, we have conducted a high-resolution analysis of these remains, combining both taphonomic and microstratigraphic data. Our results, using microstratigraphic and micromorphological analyses of sediments based on thin-sections, show that this individual was deposited in a marshy environment. Subsequently, the carcass was exploited by hominins and large felids that left their marks on the surface of some of its bones. For this purpose, the identification and characterisation of both cut marks and tooth marks were performed using high-resolution 3D modelling, geometric morphometrics, and artificially intelligent algorithms. Based on the anatomical position of both the cut and tooth marks, we propose that both the hominins and the saber-toothed cats had early access to the animal. Finally, this paper shows how an interdisciplinary approach can shed detailed light on the particular story regarding the death and processing of the carcass of a female mammoth, deposited at Fuente Nueva 3.

The Orce Basin Archaeological Zone (OZAB, Granada, Spain) extends over a surface area of some > 8.5 km2 and constitutes one of the richest Pleistocene vertebrate fossil records in western Europe including one of the oldest hominin presence in this part of Eurasia. Exceptionally rich collections of stone tools have been excavated from both of the Orce Oldowan sites: Barranco León (BL) (1.4 Ma) and Fuente Nueva 3 (FN3) (1.2 Ma), while BL has yielded a hominin deciduous lower molar. We present a multi-proxy approach to determine the palaeoeocological context of these first hominin settlements in Western Europe. By combining results from macrovertebrates, microvertebrates, as well as from pollen and stable isotopes from macrovertebrate tooth enamel, we determine whether the palaeo landscapes were dominated by savanna or open woodland. The results reveal the regional specificities of the OAZB, and also allow us to infer local features within the Orce sites. Overall, our data reveal the dominance of a typically Mediterranean climate and landscape since 1.8 Ma ago. The climatic conditions were generally more humid than at present, with warmer temperatures during the coldest months, indicating a higher net primary productivity (NPP). We find that precipitation and NPP appear to have been limiting factors for hominin presence in the OAZB. Thus, at the older palaeontological site of Venta Micena (1.6 Ma), climatic conditions appear to have been less compatible with hominin presence than during the BL and FN3 sequences, when early hominins inhabiting the OAZB were able to cope with changing climatic and environmental settings. Lastly, the comparison of the isotopic results of the Orce sites with those of the contemporaneous Shungura Formation (Ethiopia) reveals that the habitat in the westernmost part of Eurasia was distinctly unlike a typical African savanna.

CRUE-CSIC (Acuerdos Transformativos 2022), Little is known about the subsistence practices of the frst European settlers, mainly due to the shortage of archaeological sites in Europe older than a million years. This article contributes to the knowledge of the subsistence of the frst Europeans with new zooarchaeology and taphonomic data from the Palaeolithic site of Barranco León (Orce, Granada, Spain). We present the results of the analysis of the faunal assemblages retrieved in the context of new excavations undertaken between 2016 and 2020. We have followed a standard methodology for the identifcation and quantifcation of species, mortality profles, skeletal representation and taphonomic analysis. With regard to the taphonomic evidence, we have documented the extent of rounding, abrasion and other alterations. Finally, we examined traces from the activities of carnivores and hominins that led to the accumulation and alteration of the bone assemblages. Results indicate that the archaeo-paleontological deposits from Barranco León present a dual-patterned mixed taphonomic origin. The frst phase primarily involved waterborne processes (BL-D1), which led to the accumulation of lithic raw materials, a few archaeological stone tools, and some faunal remains with percussion and cutmarks. The second phase (BL-D2) contains several stone tools associated with faunal remains with more anthropogenic alterations, such as cutmarks and percussion marks. After analysing the Barranco León zooarchaeological assemblage, the present study concludes that hominins had access to the meat and within-bone nutrients of animals of diverse sizes. However, the specifc carcass acquisition mechanisms that hominins followed are less certain because the presence of tooth marks suggests that carnivores also played a role in the accumulation and modifcation of the Barranco León faunal assemblage., Ministerio de Ciencia e Innovación (MICINN), Unidad de Excelencia María de Maeztu, Universitat Rovira i Virgili, Generalitat de Catalunya, Depto. de Prehistoria, Historia Antigua y Arqueología, Fac. de Geografía e Historia, TRUE, pub

Palynological investigations in the Orce Archaeological Zone (OAZ) (Guadix-Baza Basin, Granada, Spain), Venta Micena 1 (VM1), Barranco León (BL) and Fuente Nueva 3 (FN3) are presented. This archaeological region is connected with the first Homo populations in Western Eurasia during the Early Pleistocene. The VM1 pollen record is characterized by Ephedra, and to a lesser extent, Pinus, Juniperus and evergreen Quercus, occassionally accompanied by Olea, Genisteae, Erica, deciduous Quercus, Alnus, Castanea, Fraxinus, Salix and Phillyrea. BL is dominated by Juniperus, Olea, Pinus, Poaceae, and evergreen Quercus. FN3 is characterized by an open Mediterranean woodland dominated by evergreen Quercus, Pinus, Juniperus and Olea, accompanied by deciduous Quercus, Castanea, Populus, Salix, Ulmus, Fraxinus, Pistacia, Phillyrea, Genisteae, Erica, Cistus, and Ephedra fragilis. Relic Tertiary taxa in OAZ include Carya, Pterocarya, Eucommia, Zelkova, and Juglans. The Early Pleistocene OAZ vegetation is a mosaic of different landscapes embracing mesophytes, thermophytes, xerophytes, xerothermophytes, and Mediterranean elements. These finds are compared with former pollen analyses in the region and beyond within the Iberian Peninsula.
