Wonderboom, South Africa: An Acheulean workshop with evidence of flake harvesting
There are several characteristics that can be used to identify Acheulean workshops. However, the direct flaking of raw-material outcrops can be an important step in Acheulean lithic production that is missing from the current trait list. Here, we define and introduce the first systematically documented evidence of what we refer to as ‘flake harvesting’ at Wonderboom in Gauteng, South Africa. The presence of flakes and cores from the excavated Acheulean deposit, with similar dimensions and in similar condition to those associated with the nearby flake-harvesting localities, indicate that the behaviour was associated with the Acheulean. We explain that collecting flakes in this manner is different from quarrying, and provide a recording protocol that can be applied to other localities. This could help to explore whether the behaviour has been missed previously, or whether it is a uniquely localised development. We provide a summary of Acheulean workshop traits reported by other researchers, demonstrating that several of these traits are present at Wonderboom, so that the site can now be thought of in terms of a workshop, amongst other things, and flake harvesting can be added to the list.
