Figure 1.
Three-dimensional photosimulations of microwear surfaces of all extant and extinct carnivorans analyzed.
Examples include: (A) A. jubatus (AMNH 161139), (B) P. leo (USNM236919), (C) C. crocuta (AMNH 83592), (D) P. atrox (LACMHC 6996), and (E) S. fatalis (LACMHC 2002-298).
Figure 2.
Bivariate plot of anisotropy and complexity of extant and extinct carnivorans.
Extant cheetahs (A. jubatus, ◊), African lions (P. leo, +), and hyenas (C. crocuta, □) are from Ref. 18 and supplemental unpublished samples from wild caught animals throughout Africa. The extinct American lion (P. atrox, •) and saber toothed cat (S. fatalis, ▴) are from the Pleistocene Rancho La Brea site located in southern California (see Table S1).
