Stone-tool industry of the Lower Paleolithic Period characterized by bifacial stone tools with round cutting edges and typified especially by an almond-shaped (amygdaloid) flint hand ax measuring 8-10 in. (20-25 cm) in length and flaked over its entire surface. Other implements include cleavers, borers, knives, and choppers. The name derives from the site near St.-Acheul, in northern France, where such tools were first discovered. Acheulean industry was extremely long-lived (1,500,000-110,000 years ago) and is associated with both Homo erectus and archaic Homo sapiens
