Un assemblage inhabituel d’insectivores au Miocène inférieur du Sud-Ouest de l’Europe : les talpidés et les dimylidés du bassin de Ribesalbes–Alcora …
2019
The Miocene record of talpids and dimylids in south-western Europe is very scarce. In the present work, we study for the first time the talpids and complete the description of the dimylids, already started with a new species of the genus Plesiodimylus from the Ribesalbes–Alcora Basin (MN4, lower Aragonian, early Miocene) by Crespo et al. (2018). The talpids recovered inRibesalbes–Alcora comprise themost common Desmanodon daamsi and Desmanella fejfari, for which the last known occurrence is recorded here. The dimylids comprise the species Plesiodimylus ilercavonicus, which expands the biostratigraphic record of the genus and species and has been found in a new site. On the other hand, we dis…
L’ évolution des assemblages lithiques des niveaux du Paléolithique moyen de l’Abrigo de la Quebrada (Valencia, Espagne)
2018
L’Abrigo de la Quebrada propose une séquence stratigraphique importante, avec neuf niveaux dont sept présentent des preuves d’occupation appartenant au Paléolithique moyen. De plus, l’existence d’un niveau stérile, le VI, séparant les niveaux supérieurs (II à V) des niveaux inférieurs (VII à IX), permet d’évaluer, dans une perspective diachronique, les changements constatés sur les différentes matiàres premières et sur les systémes de débitage employés pour chacune de ces deux grandes phases. Ces donne´ es sont compare´ es a` d’autres sites contemporains, dans le but d’e´valuer les normes technologiques et la gestion des ressources des ne´ andertaliens dans la zone ge´ographique de la re´gi…
Symbolic use of marine shells and mineral pigments by Iberian Neandertals 115,000 years ago.

U-Th dating of archaeological deposits of Cueva de los Aviones provides evidence for Neandertal symbolism 115,000 years ago.
Hunted or Scavenged Neanderthals? Taphonomic Approach to Hominin Fossils with Carnivore Damage
2017
Carnivore damage on Neanderthal fossils is a much more common taphonomic modification than previously thought. Its presence could have different explanations, including predatory attacks or scavenging scenarios, which are both situations with important implications concerning Neanderthal behaviour. In the present paper, we analyse several Neanderthal hominin fossils from a taphonomic and forensic perspective in order to infer the nature of the modifications observed on the bone surfaces. Fossils displaying carnivore modifications from Spain, Germany, Belgium and Greece are evaluated from a taphonomic perspective for the first time in a significant sample of hominin specimens. Our results sh…
Seasonal and habitat effects on the nutritional properties of savanna vegetation: Potential implications for early hominin dietary ecology.
2019
The African savannas that many early hominins occupied likely experienced stark seasonality and contained mosaic habitats (i.e., combinations of woodlands, wetlands, grasslands, etc.). Most would agree that the bulk of dietary calories obtained by taxa such as Australopithecus and Paranthropus came from the consumption of vegetation growing across these landscapes. It is also likely that many early hominins were selective feeders that consumed particular plants/plant parts (e.g., leaves, fruit, storage organs) depending on the habitat and season within which they were foraging. Thus, improving our understanding of how the nutritional properties of potential hominin plant foods growing in mo…
Carbon, nitrogen and oxygen isotope fractionation during food cooking: Implications for the interpretation of the fossil human record.
2017
13 pages; International audience; ObjectivesStable isotope data provide insight into the reconstruction of ancient human diet. However, cooking may alter the original stable isotope compositions of food due to losses and modifications of biochemical and water components.MethodsTo address this issue, carbon, nitrogen and oxygen isotope ratios were measured on meat aliquots sampled from various animals such as pork, beef, duck and chicken, and also from the flesh of fishes such as salmon, European seabass, European pilchard, sole, gilt-head bream, and tuna. For each specimen, three pieces were cooked according to the three most commonly-known cooking practices: boiling, frying and roasting on…
Dental calculus indicates widespread plant use within the stable Neanderthal dietary niche.
2018
The ecology of Neanderthals is a pressing question in the study of hominin evolution. Diet appears to have played a prominent role in their adaptation to Eurasia. Based on isotope and zooarchaeological studies, Neanderthal diet has been reconstructed as heavily meat-based and generally similar across different environments. This image persists, despite recent studies suggesting more plant use and more variation. However, we have only a fragmentary picture of their dietary ecology, and how it may have varied among habitats, because we lack broad and environmentally representative information about their use of plants and other foods. To address the problem, we examined the plant microremains…
Early evidence of fire in south-western Europe: the Acheulean site of Gruta da Aroeira (Torres Novas, Portugal)
2020
The site of Gruta da Aroeira (Torres Novas, Portugal), with evidence of human occupancy dating to ca. 400 ka (Marine Isotope Stage 11), is one of the very few Middle Pleistocene localities to have provided a fossil hominin cranium associated with Acheulean bifaces in a cave context. The multi-analytic study reported here of the by-products of burning recorded in layer X suggests the presence of anthropogenic fires at the site, among the oldest such evidence in south-western Europe. The burnt material consists of bone, charcoal and, possibly, quartzite cobbles. These finds were made in a small area of the cave and in two separate occupation horizons. Our results add to our still-limited know…
Uneven Data Quality and the Earliest Occupation of Europe—the Case of Untermassfeld (Germany)
2017
AbstractThe database regarding the earliest occupation of Europe has increased significantly in quantity and quality of data points over the last two decades, mainly through the addition of new sites as a result of long-term systematic excavations and large-scale prospections of Early and early Middle Pleistocene exposures. The site distribution pattern suggests an ephemeral presence of hominins in the south of Europe from around one million years ago, with occasional short northward expansions along the western coastal areas when temperate conditions permitted. From around 600,000-700,000 years ago Acheulean artefacts appear in Europe and somewhat later hominin presence seems to pick up, w…
L'enquête sur les archives de la recherche en sciences humaines et sociales (ARSHS). Premier bilan
2009
Le reperage, la collecte et la conservation des archives produites par la recherche en sciences humaines et sociales sont une preoccupation recente en France. Cet article presente une experience originale menee par le reseau des Maisons des sciences de l’homme en collaboration avec les Archives nationales et le ministere de l’Enseignement superieur aupres des archives et des centres de recherche (universites, CNRS) pour faire un inventaire des archives de la recherche. Outre le sauvetage de fonds en perdition, l’enquete vise a sensibiliser les chercheurs a la conservation des donnees qu’ils produisent et a rendre possible une histoire des pratiques de recherche et une histoire sociale des s…
