dc.description.abstractEnSibhudu rock shelter preserves one of the major sequence, over four meters thick, of Middle Stone Age artefacts in South Africa, uncovering pre-Still Bay, Still Bay, Howiesons Poort, and Sibhudan techno-complexes. The first optically stimulated dating chronology performed on single quartz grains indicated ages between 38 to 72 ka (Jacobs et al., 2008, 2017) . While the continuing excavation has uncovered deeper layers, the whole sequence has been re-sampled for optical dating. We applied several protocols on single or multiple grains aliquots of quartz or potassium feldspar grains, including SAR, IR50, pIR-IR290, pIT, and RF , in order to improve and extend the final chronology. Here we show that, other than the RF ages, which overestimate the mean of other age estimates by over 30%, ages for the various protocols are usually within 10% of their mean. Although the excavation has not yet reached bedrock, our results have extended the chronology of Sibhudu back at least until late Marine Isotope Stage 6.
