Fig. 6. Tooth breakage percentages for Optima Local Fauna (Miocene, late Hemphillian, Oklahoma, USA), Pleistocene, and modern felids and canids. Higher percent tooth breakage corresponds with darker shade. Pleistocene and modern data from Van Valkenburgh (2009).图6 展示了美国俄克拉荷马州晚赫姆菲兰期中新世奥普塔马本地动物群、更新世及现生猫科和犬科动物的牙齿破损率。牙齿破损率越高，对应色块颜色越深。更新世与现生类群的数据引自Van Valkenburgh（2009）。
