The variability and the chronology of the Acheulian sequence is documented by systematic, modern and controlled investigations in various sites (Unit L and Hominid Cave at Thomas I Quarry, Rhinoceros Cave at Oulad Hamida 1 Quarry, Sidi Abderrahman Extension Quarry, Bear’s Cave and Cap Chatelier at Sidi Abderrahman Quarry) which have taken place within the framework of the Franco-Moroccan co-operative project “Casablanca”. In order to manage the excavation data and to explore the taphonomic nature of Unit L, Hominid Cave and Rhinoceros Cave, where research is still in progress, an approach combining a Geographic Information System (GIS) and spatial analysis techniques was developed, incorporating all existing information produced from previous excavations and recent surveys of the sites. The amalgamation of this data into a GIS has resulted in a digital database that allows the production of simultaneous or separate visualizations and analyses of the fossils, artifacts and geological materials within their original spatial contexts and also permits intra-site spatial analyses that allow a comprehensive investigation of the site formation processes.展开更多

We examined features and cultural remains recovered from Locality 2 at Shuidonggou, a Late Paleolithic site, focusing on early occupants' survival behaviors and settlement patterns, as indicated by evidence regarding the functional organization of the site. Three-dimensional data from unearthed remains (including lithic assemblages, faunal remains, ornaments, etc) were used to reconstruct intra-site use patterns of Cultural Layer 2, which yielded seven earth-pit hearths and tens of thousands of artifacts and bones. We discuss the population size and group composition, as well as the functions of the living spaces, based on the analysis of the hearth patterns and the ostrich eggshell ornaments surround the hearths. In conclusion, Cultural Layer 2 of SDG Locality 2 appears to have functioned as a base camp for ancient foragers, where occupants produced tools, as well as preparing and consuming food.展开更多
