Victoria West cores from The Victoria West: earliest prepared core technology in the Acheulean at Canteen Kopje and implications for the cognitive evolution of early hominids

Victoria West cores with overshot preferential removals (a, b, c) and small sized removal (d). Note that although the size of specimen a is also small, the preferential removal is still large when compared with the overall size of the core. The yellow arrows show the preparation of the two surfaces, the red arrows show the preferential flake removal directions, and the blue arrows show scars overlapping the preferential removal. a, b , c and d correspond to the specimens CK2919, CK8091, CK4916 and CK4597 respectively (see Table S1 for raw data).
