Biology
Borophagini were short-faced, heavy-jawed canids, usually massive in size. They were primarily carnivores but dentition demonstrates omnivore traits.

The clade includes: Cormocyon, Desmocyon, Metatomarctus, Euoplocyon, Psalidocyon, Microtomarctus, Protomarctus, and Tephrocyon.

With the clade comprising many genus and subtaxa, the distribution of fossil specimens for Borophagini is widespread throughout the entire continent extending from coast to coast as well as Florida to western Oregon to Panama.
