    Taphonomic and spatial study of the archeological site DS from Bed I in Olduvai Gorge (Tanzxania)

    Faunal remains recovered at early archaeological sites dated to around 2 million years (Ma) play a critical role in discussions about the evolution of early hominin behavior. Anthropogenic assemblages from this time period are scarce, however and, until recently, most of the available evidence on the behavior of early Homo has been almost exclusively obtained at the FLK Zinj site from Bed I in Olduvai Gorge (Tanzania). The recent discovery of DS (David’s Site, 1.84 Ma) and two additional hominin-made accumulations on the same paleosurface as the iconic site of FLK Zinj provides an invaluable opportunity to address key issues regarding early hominin lifestyles, particularly their subsistence behaviors and their foraging capabilities. The DS site has been extensively excavated and is exceptionally well preserved. Over the past years, significant advances in taphonomic and spatial statistical techniques have been made, which mainly involve the combination of several variables in multivariate approaches and the use of machine learning algorithms. The application of these methods to the faunal fossil record within extended frames of reference helps overcome equifinality when trying to detect the main agent of site formation and interpret site function...
