Mean, standard deviation (SD), and p-values for dental microwear characters (Asfc, epLsar, Smc, Tfv, HAsfc(3×3), HAsfc(9×9)) of extinct taxa from different temporal pits at Rancho La Brea, California.

*Significant values (pS. fatalis consists of only specimens from Pits 3, 67, and 91; however, P. atrox required supplemental specimens from similarly aged pits to increase sample sizes, temporally. Asfc, area-scale fractal complexity; epLsar, anisotropy; Smc, scale of maximum complexity; Tfv, texture fill volume; HAsfc(3×3), HAsfc(9×9) heterogeneity of complexity in a 3×3 and 9×9 grid, respectively.
