Protepicyon is an extinct genus of the family Borophaginae which lived during the Barstovian stage of the Middle Miocene subepoch living 16.3—13.6 mya, existing for approximately 3.3 million years.[1]

It was named by Wang in 1999 and assigned to Borophagina by Wang et al. that same year. The fossil distribution is represented by one find in California.


Protepicyon was named by Wang et al. (1999). Its type is Protepicyon raki. It was assigned to Borophagina by Wang et al. (1999).[2]


Two specimens were examined by Legendre and Roth for body mass. The first specimen was estimated to weigh 36.4 kg (80 lb). The second specimen was estimated to weigh 32.2 kg (71 lb).[3]


Protepicyon contains one species: P. raki.
