Résumé
East Africa has provided the earliest known evidence for Oldowan stone artifacts andhominin-induced stone tool cutmarks dated to ~2.6 million years (Ma) ago. The ~1.8-million-year-old stone artifacts from Ain Hanech (Algeria) were considered to represent theoldest archaeological materials in North Africa. Here we report older stone artifacts andcutmarked bones excavated from two nearby deposits at Ain Boucherit estimated to~1.9 Ma ago, and the older to ~2.4 Ma ago. Hence, the Ain Boucherit evidence shows thatancestral hominins inhabited the Mediterranean fringe in northern Africa much earlierthan previously thought. The evidence strongly argues for early dispersal of stone toolmanufacture and use from East Africa or a possible multiple-origin scenario of stonetechnology in both East and North Afri
