Oxyaenidae ("sharp hyenas") is a family of extinct carnivorous placental mammals.[3] Traditionally classified in order Creodonta, this group is now classified in its own order Oxyaenodonta ("sharp tooth hyenas") within clade Pan-Carnivora in mirorder Ferae. The group contains four subfamilies comprising fourteen genera. Oxyaenids were the first to appear during the late Paleocene in North America, while smaller radiations of oxyaenids in Europe and Asia occurred during the Eocene.[4]
Etymology
The name of order Oxyaenodonta comes from grc ὀξύς- (oxús-) 'sharp', name of hyena genus Hyaena and from grc ὀδούς (odoús) 'tooth'.
The name of family Oxyaenidae comes from grc ὀξύς- (oxús-) 'sharp', name of hyena genus Hyaena and taxonomic suffix "-idae".[5]
Description
They were superficially cat-like mammals that walked on flat feet, in contrast to modern cats, which walk and run on their toes. Anatomically, characteristic features include a short, broad skull, deep jaws, and teeth designed for crushing rather than shearing, as in the hyaenodonts or modern cats.[citation needed]
Oxyaenids were specialized carnivores that preyed on other terrestrial vertebrates, eggs and insects. They were capable of climbing trees, which is suggested by fossil evidence of their paws.Lua error: Internal error: The interpreter exited with status 1.
