Fig. 15. Elongate metacarpals 4 and 5 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America
Fig. 15. Elongate metacarpals 4 and 5 of (A) Borocyon neomexicanus (F:AM 68242) from Standing Rock Quarry and (B) B. robustum (F:AM 68254) from Blick Quarry, Sandoval Co., New Mexico, demonstrating that the Borocyon lineage persisted in the southwestern United States from latest Arikareean into the early Hemingfordian. The only Hemingfordian record of Borocyon in the Southwest are these two metacarpals from Blick Quarry.
Fig. 12 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America
Fig. 12. Holotype cranium of Borocyon neomexicanus (F:AM 49239), Standing Rock Quarry, Zia Sand Fm., Sandoval Co., New Mexico. A, Dorsal view; B, ventral view. This is the only known cranium and is an old adult with worn teeth: P1–P4, M1–M3. Although reduced in size, an M3 persists in this species.
Fig. 13 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America
Fig. 13. Basicranium of Borocyon neomexicanus (F:AM 49239), Standing Rock Quarry, Zia Sand Fm., Sandoval Co., New Mexico. A, Right auditory region; B, left auditory region. Despite crushing, the auditory bulla and surrounding basicranium are anatomically similar to the bulla and basicranium of Daphoenodon superbus. The bulla of the Standing Rock amphicyonid is a thin-walled, flask-shaped, single chamber, as is the rudimentary auditory bulla of D. superbus.

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.
Fig. 31 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America
Fig. 31. Comparison of the astragalus of Borocyon robustum (A, B) and Amphicyon galushai (C, D). Dimorphic astragali within each species are thought to represent large males (B, D) and smaller females (A, C).
Fig. 21 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America
Fig. 21. Comparison of the distal humerus of Borocyon robustum (right, UNSM 26420) and Amphicyon galushai (left, UNSM 26375). The narrow distal humerus and symmetric olecranon fossa of B. robustum parallel the form of the distal humerus of the wolf and cheetah, indicating parasagittal orientation of the forelimb with minimal elbow eversion.

Fig. 24. Comparison of the carpus (anterior view) of Borocyon robustum and those of Panthera leo, Canis lupus, and Ursus arctos. See text for discussion. 1, Elevated bony ridge on scapholunar forcing ulnar deviation of the forepaw during flexion of the wrist; 2, scapholunar process inserted in concavity of magnum preventing hyperextension within the carpus (this stop mechanism is maximally developed in the cheetah). Abbreviations: a, scapholunar; b, carpal cuneiform; c, unciform; d, magnum; e, trapezoid; f, trapezium.
