It was first named by Xiaoming Wang and Richard L. Tedford in 1992, who described it as a primitive borophagini genus after comparing it to Nothocyon geismarianus. The period of extinction overlaps the Late Oligocene and Early Miocene supepochs according to fossil record. MorphologyFossil specimens of two individuals' body mass were examined by Legendre and Roth. The first specimen was estimated to weigh 2.79 kg (6.1 lbs). The second specimen was estimated to weigh 2.82 kg (6.2 lbs).[2] Sister generaDesmocyon, Euoplocyon, Metatomarctus, Microtomarctus, Protomarctus, Psalidocyon, and Tephrocyon.
