My overarching research interests cover the African Middle and Later Stone Age, the European Middle Palaeolithic and hunter-gatherer subsistence behaviour. For example, to understand Middle Stone Age coastal foraging behaviour and (the impact of) local climatic variation, I analysed shellfish from Blombos Cave (South Africa). I found for instance that the hunter-gatherers at Blombos timed their visits to the coast with low tides; in addition, the distance from the cave to the coastline determined which shellfish species they would bring to the site (Fig 1).
Currently, I am applying residue and use-wear studies to scrapers and grindstones from several southern African Stone Age sites (Fig 2). My goal is to illuminate the exploitation of plant resources, a generally overlooked food category for this period. However, preliminary results reveal at least some scrapers were used to work hide, of which we also know little. One of the recurring residues I find on the scrapers is a possible adhesive mix that contains ochre. These finds sparked another research project on prehistoric adhesive technology. To properly unravel adhesives and other residues, I am revisiting the use of spectrographic and chemical material analysis. Currently, I am also co-developing a fieldwork project to study the Middle to Later Stone Age transition in southern Africa.
