Occlusal Enamel Complexity in Middle Miocene to Holocene Equids (Equidae: Perissodactyla) of North America
Figure 1
Representative teeth of each tribal-level group in this study.
(A) Hipparionini, (B) Equini, (C) “Merychippini,” and (D) “Anchitheriini.” Each tribe has a distinct enamel pattern; the patterns decrease in complexity from A to D.
