Gestion des matières premières et comportements techniques dans le Middle Stone Age africain: Les assemblages lithiques de la grotte du Porc-Épic (Dire Dawa, Éthiopie)

This study examines the lithic assemblage from a cave site, Porc-Épic, located in Dire Dawa, Ethiopia. The assemblage is representative of the Middle Stone Age and documents an increased sophistication in lithic production, with greater technological variability shown in the production of blades, flakes, bladelets, points and so on. David Pleurdeau examines the assemblage in detail and argues that changes in the relationship between humans and their environment in the Middle Stone Age were in part due to the diversification and regionalisation of stone tool production at this time, as seen at Porc-Épic.
