Fig. 1. Dental topography: a DEM of a chimpanzee tooth (upper left) and contour lines (upper right). Average surface slope (lower left) and aspect (lower right).

Fig. 2. Principal components analyses of upper M2 dental topography for platyrrhine monkeys with different primary diets (top) and for frugivores with different secondary diets (bottom). Sharpness, slope, angularity, and relief variables contribute the most to PC1, whereas OPC and patch size contribute the most to PC2. Specimens included here have "stage 1" slight wear. Data are from and further details can be found in Ungar et al., 2016.

Fig. 3. A dental microwear texture analysis: (A) a DEM of the teeth of a leaf-eating howler monkey; (B) a grass-eating gelada; (C) a hard-object-feeding capuchin; and (D) a hard-object-feeding mangabey; (E) area-scale tiling and (F) an area-scale fractal complexity plot of (a) a howler monkey and (b) a capuchin. Data originally reported in Scott et al., 2005; Scott, Teaford, and Ungar 2012.
