borophaginae

Genus: Epicyon

(meaning “more than a dog”)

….a extinct genus of bone-crushing dogs that lived in North America during the middle Miocene to late Miocene. Like other bone-crushing dogs members of this genus had large teeth and jaws which were used to crush bones, as suggested in their common name. Members of Epicyon were a lot larger than other borophagines with some species  weighing over 370 pounds and were around the size of a bear. Epicyon was one of the last of the borophagines and shared its habitat with numerous other canids like Canis lepophagus, the first wolf.
