The Early Oldowan Stone-Tool Assemblage from Fejej FJ-1A, Ethiopia

Located in the Omo-Turkana basin at the northern limit of the Koobi Fora sedimentary Formation, the Fejej region has recently proven to be a rich study area for understanding early hominin behaviour and paleoenvironmental conditions. Among the rich fossiliferous and stone artefact localities discovered so far at Fejej, the FJ-1a archeological site has yielded a faunal and lithic assemblage in primary context. The archeological level is situated within a 15 meter fluvial sequence beneath a volcanic tuff. Geochronological data from the FJ-1 sequence indicate an age of nearly 1,9 Ma for the FJ-1a artefact level. The stone industry was knapped from locally available raw materials (mainly quartz and basalt) and rocks had been carefully selected according to specific petrographical and formal criterion. Hominins mastered several distinct stone knapping methods and used more or less exhaustive reduction sequences in order to produce small flakes. The different techniques used for stone reduction are defined in this paper thanks to a series of refits of flakes onto cores. Along with the refits, an in-depth analysis of the flakes, cores and worked pebbles provides an overview of the technological capacities of hominins present at the site nearly 2 million years ago. After the Fejej FJ-1a site was abandoned the archeological materials were rapidly buried, leaving an almost undisturbed archeological level. This site appears to represent a short episode of hominin occupation.

Première mise en évidence d'une séquence éémienne à restes humains dans le remplissage de la Baume Moula-Guercy (Soyons, Ardèche)

Abstract Since 1992, excavations at Baume Moula-Guercy have been providing abundant palaeontological and archaeological remains. Palaeontological results allow us to distinguish three main climatic cycles and to suggest a biochronological hypothesis. Lower stratigraphical levels of deposits are representative of a cold period which can be related to the end of the Middle Pleistocene (stage 6 of the oceanic temperatures curve). Upper stratigraphical levels are also representative of a cool period corresponding to stage 4 of the oceanic temperature curve. Between those levels, a homogeneous and thick stratigraphical level, containing an abundant temperate and forested fauna, has been identified. It corresponds to the Eemian period, sensu lato. The wealth of documentation and the great variety of identified species make the Baume Moula-Guercy a reference site for the study of the transition between the Middle and the Upper Pleistocene in Mediterranean Europe.

Neanderthal selective hunting of reindeer? The case study of Abri du Maras (south-eastern France)

Monospecific exploitation of reindeer by Neanderthals is a common behaviour in the Upper Pleistocene of Western Europe. However, reindeer-dominated assemblages have largely been reported from regions of northern Germany and south-western France, with few examples noted in south-eastern France, where faunal assemblages yield most of the time a variety of other large ungulates such as red deer, horse and diverse bovids. Here, we present multi-strand (bio- and eco-) archaeological datasets from the site of Abri du Maras (level 4.1), situated at the mouth of the Ardèche and Rhône rivers, a new example of a reindeer-dominated Neanderthal site in south-eastern France. Dated to the beginning of the MIS 3, the zooarchaeological assemblage is dominated by reindeer (88% of the NISP, representing 16 individuals) but also includes horse, bison, giant deer (Megaloceros giganteus), red deer, ibex and lagomorphs. The combination of zooarchaeological, cementochronological and tooth microwear analyses evidence a single species-dominated spectrum, with catastrophic mortality and repeated autumnal deaths. This integrated approach provides an extensive picture of human subsistence behaviour, pointing to short-term hunting episodes of reindeer herds in an exceptional context of a quasi-exclusive Neanderthal accumulation. The high number of individuals and selective butchery may correspond with a cooperative and planned mass hunting strategy. The multidisciplinary approach undertaken here also incorporating paleontological, charcoal, ecological and isotopic analyses places the archaeological and zooarchaeological data within a broader regional palaeoenvironmental framework, providing valuable landscape-contextual information. The zooarchaeological data suggest a subsistence behaviour different from other Neanderthal reindeer-dominated assemblages often connected with specialised butchery or hunting sites.
