Mammacyon is an extinct genus of large, mostly carnivorous bone-crushing mammals known as bear dogs, of the family Amphicyonidae endemic to North America during the Oligocene to Miocene living from 30.8—20.6 Ma and existed for approximately 10.2 million years. [1]

Taxonomy

Mammacyon was named by Loomis (1936).[2] Its type is Mammacyon obtusidens. It was assigned to Amphicyonidae by Loomis (1936) and Carroll (1988); and to Temnocyoninae by Hunt (1998).[3]

Morphology

A single specimen was examined by Legendre and Roth for body mass and was estimated to weigh 39.3 kg (87 lb).[4]
