Epicyon ("more than a dog") is a large, extinct, canid genus of the subfamily Borophaginae ("bone-crushing dogs"), native to North America. Epicyon existed for about 15 million years from the Hemingfordian age of the Early Miocene to the Hemphillian of the Late Miocene.
Epicyon, which was about 1.5 m (5 ft) long, had an estimated weight of 91-136 kg (200-300 lb). Epicyon had a massive head and powerful jaws, giving its skull a lion-like shape rather than that of a wolf.
Epicyon was one of the last of the Borophaginae and shared its North American habitat with other canids:
Borophagus 23.3 to 3.6 million years ago (mya)
Carpocyon from 20.4 to 3.9 mya
Paratomarctus from 16.3 to 5.3 mya
Aelurodon from 15.97 to 5.332 mya
Canis lepophagus from 10.3 to 1.8 mya
