Frequencies of formal tools in the HP levels of Sibudu, Klasies River Cave 1A and Rose Cottage.

1Bifacial points are excluded from these counts to avoid confusion with the 17 Still Bay points which are intrusive in layer PGS and have been assigned to the Still Bay. Quartz bifacial points have been described by [37]. Relative frequencies of retouched pieces in PGS are also not indicated because, as explained, mixing by intrusive elements affects all four squares of our PGS sample. Backed tools are very distinctive and we can confidently assign them to the HP. But we cannot assign all other retouched pieces of PGS to either the Still Bay or the HP. Deacon’s sample of Klasies HP Upper and DRG from Sibudu are not included because the samples are quite small.
