Fig. 14 in Long-Legged Pursuit Carnivorans (Amphicyonidae, Daphoeninae) From The Early Miocene Of North America

Fig. 14. Elongate radii of (A) female and (B) male Borocyon neomexicanus, Standing Rock Quarry, Zia Sand Fm., Sandoval Co., New Mexico. Note large distal radial exostosis (arrow) of the male, a trait also present in Daphoenus vetus and Daphoenodon superbus but not developed in B. robustum despite a sample of eight radii from the Hemingford and Bridgeport Quarries. The single radius of Borocyon cf. B. robustum from Florida retains a small exostosis.
