Herries provides a timely review of the archaeological and dating evidence of the transition from the Acheulean to the Middle Stone Age (MSA) in southern Africa, however, in relation to the site of Twin Rivers, Zambia he makes several fundamental errors of interpretation that demand correction. The stratigraphic sequence of the site is admittedly complex, but it deserves a more careful analysis than that offered by Herries. This detailed response by the most recent excavator of the site addresses Herries critique by placing the site in its historical context and then dealing with the central issue of the association of dated speleothem with the surviving archaeological deposits. Herries is shown to have mistakenly combined the dates from two separate cave passages and to have misunderstood the published sections, plans, and taphonomic assessment of each excavation area. His reinterpretation of the site as being significantly younger than published is based on a conflation of unrelated data.
