New excavations have been undertaken at Diepkloof Rock Shelter (DRS: South Africa) since 1999. It is one of the very few sites where Howiesons Poort and Stillbay assemblages can be collected from the same archaeological sequence. These Middle Stone Age techno-complexes are particularly interesting for their affinities with the much younger Later Stone Age facies, and their association with evidence for symbolic behaviour. Establishing their chronology is therefore particularly important for the understanding of the apparition and the evolution of the so-called modern behaviours. Data already available Suggest ages ranging from 55 to 80 ka for the Howiesons Poort and from 70 to 80 ka for the Stillbay techno-complexes in several South African sites. The thermoluminescence dating undertaken at DRS on 22 stone samples originating from the entire stratigraphic record indicates intervals starting 10-50 ka earlier for these techno-complexes in this site. Possible caveats in the dating process are examined but to the best of our Current knowledge must be rejected. (C) 2008 Elsevier Ltd. All rights reserved.
