"Reconstructing Middle Stone Age mobility patterns from raw material tr" by Alex Mackay, Christopher J.H. Ames et al.
South Africa’s Still Bay technocomplex (77–70 ka) is an early example of a technological system organised around the production of bifacial points. Noting the diversity of raw materials used and the frequency of non-local raw materials found among excavated bifacial point assemblages, numerous researchers have argued that Still Bay foragers were highly mobile. This pattern, however, is in contrast to that observed in some open-air surface Still Bay assemblages, where raw material diversity among bifacial points is low and local rocks dominate. We resolve this apparent discrepancy by combin...
