Fig. 27 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America

Fig. 27. Placement of the fovea capitis femoris for the femoral ligament in Borocyon robustum and some living carnivorans. In cheetah, puma, and wolf the fovea is more centrally situated on the femoral head, whereas in the lion, tiger, and B. robustum it is more posteriorly placed, indicating a somewhat more abducted femur in these large felids and Borocyon. Diagram of articulated femur and pelvis shows femoral head of B. robustum fully adducted; the femur is more abducted in normal stance. A, Acinonyx jubatus; B, Canis lupus; C, Felis concolor; D, Panthera leo; E, Borocyon robustum; F, Panthera tigris.

Fig. 37 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America

Fig. 37. Hypothetical restoration of the skeleton of Borocyon robustum (A) compared to the holotype skeleton of Daphoenodon superbus (B, from Peterson, 1910), representing the two end-member species of the Borocyon lineage during the early Miocene in North America. Fossils show that Borocyon robustum, the terminal species of the subgenus, was widely distributed from the Pacific Northwest to the Gulf Coast of Florida by the end of the early Hemingfordian.
