"Pachyaena" (literally, "Thick Hyena") was a genus of heavily built, relatively short-legged mesonychids that originated from Asia. The species ranged in size from a coyote to a bear. During the height of their influence, the species of "Pachyaena", like those of "Dissacus" before them, ranged from Europe to North America.
