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.

Le gisement paléolithique moyen de Payre est situé dans le sud-est de la France, dans la moyenne vallée du Rhône. Les fouilles, qui s 'y déroulent depuis 1990, livrent une séquence datée des stades isotopiques 7 à 5, 6 à 5 pour les occupations humaines. Les observations à la fouille permettent de visualiser les limites d'une cavité aujourd'hui effondrée. Les hommes seraient venus à plusieurs reprises dans cette cavité et auraient occupé en dernier lieu un abri sous roche. Les données du remplissage, associées à celles livrées par l'assemblage osseux, aboutissent à proposer aujourd'hui une reconstitution de la morphologie du site aux différents moments des occupations humaines et à donner une idée du cadre de vie choisi par les hommes, en particulier pour des occupations sans doute de courte durée.
