Oxetocyon
''Oxetocyon'' ("beginning dog") is an extinct genus of the subfamily ''Borophaginae'' and a terrestrial canine which inhabited North America during the Whitneyan stage (33.3 Mya)—(30.8 Mya) of the Oligocene epoch.〔(PaleoBiology Database: ''Oxetocyon'' Taxonomy, Species )〕 ''Oxetocyon'' existed for approximately . ==Taxonomy== The teeth of ''Oxetocyon'' indicate a more hypocarnivorous diet, as is found in the living Raccoon Dog, and suggest a potential relationship to the unusual borophagine ''Otarocyon''. ''Oxetocyon'' is distinguished from ''Otarocyon'' by its own set of dental specializations for an omnivorous diet, particularly by the presence of a cleft that divides each upper molar into front and back halves.〔Xiaoming Wang, R.H. Tedford, and B.E. Taylor. 1999. (Phylogenetic systematics of the Borophaginae )〕
