Sunkahetanka is an extinct genus of small bone crushing omnivorous mammal (similar to a dog of the family Canidae) which inhabited North America during the Oligocene living from 30.8—26.3 Ma and existed for approximately 4.5 million years. [1]
Taxonomy
Philotrox was named by Macdonald (1963).[2] It was synonymized subjectively with Enhydrocyon by Swisher (1982); it was revalidated by Carroll (1988), Wang (1994) and Wang and Tedford (1996). It was assigned to Canidae by Macdonald (1963), Carroll (1988), Wang (1994) and Wang and Tedford (1996).[3]
Morphology
Two specimens were examined by Legendre and Roth for body mass. The first specimen was estimated to weigh 12.8 kg (28 lb). The second specimen was estimated to weigh 13.8 kg (30 lb).[4]
