Dental Microwear Textures Of Paranthropus Robustus From Kromdraai, Drimolen, And An Enlarged Sample From Swartkrans: Ecological And Intraspecific Variation, Alexandria Sachiko Peterson

Graduate Theses and Dissertations

The original microwear texture baseline for South African hominins was done by Scott et al. (2005) and concluded that Paranthropus robustus exhibited higher complexity values (Asfc) that are seen in occasional hard object feeders. Australopithecus africanus has higher anisotropy values (epLsar) consistent with consuming tough objects. This study expands upon this baseline by increasing the sample size from n = 9 for P. robustus and n = 10 for Au. africanus to n = 66 and n = 44, respectively. Additionally, this study incorporates multiple different sites and deposits. The P. robustus sample includes Drimolen, Kromdraai, and an expanded sample …
