Epicyon had a massive head and powerful jaws that were well adapted for bone-crushing, with enlarged fourth premolars like some hyenas, giving its skull a lion-like shape rather than having a skull similar in shape to that of a wolf; the adaptation would have allowed Epicyon to scavenge as well as hunt, giving it access to the nutritious marrow other contemporary carnivores couldn't access.
Caninae (whose members are known as canines (/ k eɪ n aɪ n z /) [6]: 182 is the only living subfamily within Canidae, alongside the extinct Borophaginae and Hesperocyoninae.
