Pachyaena Gracilis
''Pachyaena'' (literally, "thick hyena") was a genus of heavily built, relatively short-legged mesonychids, early Cenozoic mammals that evolved before the origin of either modern hoofed animals or carnivores, and combined characteristics similar to both. The genus likely originated from Asia and spread to Europe, and from there to North America across a land bridge in what is now the North Atlantic ocean. Various described species of ''Pachyaena'' ranged in size from a coyote to a bear. However, recent work indicates that ''Pachyaena'' is paraphyletic, with ''P. ossifraga'' being closer to ''Synoplotherium'', ''Harpagolestes'' and ''Mesonyx'' than to ''P. gigantea''. Unlike many mesonychids, ''Pachyaena'' is known from skeletal material in addition to skulls and jaws. Analysis of three wolf- to bear-sized species from the early Eocene of Wyoming (Willwood formation) indicates they all had many adaptations for running, including paraxonic compressed feet with a vestigial first di ...
