Creating a Chronocline of the Diet of Theropithecus From Low-magnification Stereomicroscopy: How Has the Diet of Theropithecus Changed Over Time?

摘要: The primate genus Theropithecus is represented at various Plio-Pleistocene sites including the Pliocene site of Makapansgat (2.9 mya), early Pleistocene cave Swartkrans (1.8 late deposits from Elandsfontein (700,000 ka) and by extant gelada baboons Ethiopia. To examine how diet has changed over time in this genus, dental microwear features darti (n=2), danieli (n=8), (n=2) oswaldi (n=1) Parapapio whitei (n=14), Papio robinsoni (n=16) ursinus (n=13) were examined under low-magnification (35x) using light refractive technology. Although there a significant relationship between small pits fine scratches, Analysis Variance followed Tukey’s post-hoc tests failed to demonstrate groupings. However, bivariate analyses suggest that as scratch count increases, pit decreases. results much dietary variation modern extinct baboons, but relies somewhat more on grassland resources than did their counterparts.
