Borophagus littoralis ("coastal glutton") is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the early Miocene epoch (23.3 Mya) through the Pliocene epoch (4.9 Mya).

Though not the most massive borophagine by size or weight, it had a more highly evolved capacity to crunch bone than earlier, larger genera such as Epicyon, which seems to be an evolutionary trend of the group (Turner, 2004).

[1] Borophagus littoralis possibly led a hyena-like lifestyle scavenging carcasses of recently dead animals.

[3] Its crushing premolar teeth and strong jaw muscles would have been used to crack open bone, much like the hyena of the Old World.

The adult animal is estimated to have been about 80 cm in length, similar to a coyote, although it was much more powerfully built.
