Range of Oxetocyon based on fossil distribution |
Oxetocyon ("beginning dog") is an extinct monospecific genus of the Borophaginae subfamily of canids native to North America. It lived during the Early Oligocene epoch,[1] existing for approximately 2.5 million years. Fossils have been found in Nebraska and South Dakota.
Fossils of Oxetocyon are rare and, as a result, the genus is poorly known, and only the teeth, dentaries, and a fragmentary skull have been reported. The teeth of Oxetocyon indicate a 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.[2]
