Otarocyon
''Otarocyon'' ("large eared dog") is an extinct genus "bone crushing dog" of the family ''Borophaginae'' and a terrestrial canine which was small in size endemic to North America during (Orellan & Geringian stage) of the Oligocene epoch, ~33.9—20.6 Ma.〔(PaleoBiology Database: ''Otarocyon'' Taxonomy, Species )〕 ''Otarocyon'' existed for approximately . ==Taxonomy== ''Otarocyon'' was a small borophagine characterized by a short, broad skull, a specialized middle ear, simple, tall premolar teeth, and molars that are incipiently adapted to a hypocarnivore diet. Despite its Oligocene age, the skull of ''Otarocyon'' shows several striking similarities to the living Fennec Fox (''Vulpes zerda''), particularly in the structure of its middle ear. The similarities are probably convergent, but they suggest that ''Otarocyon'' may have been similar in its appearance and habits.〔(Phylogenetic systematics of the Borophaginae (Carnivora, Canidae) )〕
