Cynodesmus is an extinct genus of omnivorous canine which inhabited North America during the Oligocene living from 33.3—-26.3 Ma and existed for approximately .
Cynodesmus was one of the first canids to truly look dog-like. At around in length, it was about the same size as a modern coyote, but had a shorter skull, heavier tail, and longer rump. The shape of its limbs suggests that Cynodesmus was not a very good runner compared to most other canids; it probably attacked prey from an ambush. Unlike modern dogs, it had five toes on each foot, bearing partially retractable claws.
Usage examples of "cynodesmus".
Despite its evidently distinct digitigrade mode of locomotion, moderately long legs, and heavy tail, its three upper molars distinguished it as an ancestor of Amphicyon and through it of all modern bears—unlike Cynodesmus, of which Danchekker also had a specimen, whose upper dentition of two molars put it between Cynodictis and contemporary Canidae.
