FIGURE 3 in Paleoecology of the Rhinocerotidae (Mammalia, Perissodactyla) from Béon 1, Montréal-du-Gers (late early Miocene, SW France): Insights from dental microwear texture analysis, mesowear, and enamel hypoplasia
FIGURE 3. Principle of mesowear scoring with the main variables illustrated (occlusal relief and cusp shape) and examples on rhinocerotid teeth.
