Occupations humaines de l’Oldowayen ancien et facteurs en-vironnementaux : interrelations et évolutions à partir des en-sembles archéologiques de la Formation de Shungura (Basse Vallée de l'Omo, Éthiopie)

Abstract : The appearance of stone tool making behavior In the Shungura Formation coincides with the appearance of the early Oldowan. It lasts over a limited time period (Member F and the lower part of Member G: 2.32 Ma to 2 Ma), while hominid fossils are present in all members, from 3.6 Ma to 1 Ma. A multi-scalar approach was developed for assessing potential interrelations and co-evolution be-tween Early Oldowan human occupations and environmental factors. This approach has allowed to include an extensive set of archaeological and paleoenvironmental data (a hundred of occurrences in Member F and ca. fifty occurrences in the lower part of Member G, thousands of faunal remains from Members E and F, and field geological data). Depending on the spatial and temporal resolution of these different records, I have defined three scales of analysis, from archeological complex scale, to study area and formation scales. The combination of spatial and taphonomical analyses of archeo-logical data, coupled with the analysis of faunal assemblages, suggest that only few archeological occurrences correspond to primary occupations in Member F. They are all located in the lower part of Member F, in the vicinity of the Omo paleoriver, in a global context of opening up and drying of the environment. Additionally, the differential spatial distribution of several faunal taxa between the northern and southern parts of the Type area could mark a greater extension of wet areas in the southern part of the Shungura Formation.
