Abstract

Prepared core technology illustrates in-depth planning and the presence of a mental template during the core reduction process. This technology is, therefore, a significant indicator in studying the evolution of abstract thought and the cognitive abilities of hominids. Here, we report on Victoria West cores excavated from the Canteen Kopje site in central South Africa, with a preliminary age estimate of approximately 1Ma (million years ago) for these cores. Technological analysis shows that the VictoriaWest cores bear similarities to the ‘Volumetric Concept’ as defined for the Levallois, a popular and widely distributed prepared core technology from at least 200 ka (thousand years ago). Although these similarities are present, several notable differences also occur that make the Victoria West a unique and distinctive prepared core technology; these are: elongated and convergent core shapes, consistent blow directions for flake removal, a predominance of large side-struck flakes, and the use of these flakes to make Acheulean large cutting tools. This innovative core reduction strategy at Canteen Kopje extends the roots of prepared core technology to the latter part of the Early Acheulean and clearly demonstrates an increase in the cognitive abilities and complexities of hominids in this time period.

Description

Figure S1: 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).
Figure S2: Victoria West cores with small removals (a, b, c) and non-ideal blow direction (d). The yellow arrows show the preparation of the two surfaces, and the red arrows show the preferential flake removal directions. a, b , c and d correspond to the specimens CK3708, CK8702, CK5837 and CK3936 respectively (see Table S1 for raw data).
Figure S3: Victoria West cores from the top of the layer containing the Victoria West core assemblage. 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 CK3142, CK3004, CK2225 and CK2208 respectively (see Table S1 for raw data).
