A stone industry of the Lower Palaeolithic of west-central Africa, developed from a Sangoan predecessor and characterized by tools appropriate for rough woodwork. Lupemban is found in northern Angola and southern Zaire and an important dated site is at Kalambo Falls on the Zambia/Tanzania border. In contrast with the Sangoan, Lupermban assemblages are marked by the fine quality of their bifacial stoneworking technique on elongated double-ended points, large sidescrapers, and thick core-axes. The industry spans from before 30,000 BC until c15,000 BC.
