The genus Hyaenodon contains a wide size range of individual species, with some barely larger than weasels. Others, like H. gigas, were quite large and could weigh over a thousand pounds. Hyaenodons had large skulls, long snouts, short necks, and relatively long and slender bodies. Despite the fact that their name means “hyena tooth”, Hyaenodon teeth were mostly suited for shearing meat from bone, whereas a hyena’s teeth are designed for crushing bones.
