What is "nothocyon"

Nothocyon is an extinct genus of carnivoran which inhabited North America during the late Oligocene. At one time, many species of the dog family Canidae were placed in Nothocyon, but new fossils showed that the type species of Nothocyon, N. geismarianus, is more closely related to bears. The other species have been reassigned to other genera such as Cormocyon.
