Ysengrinia is an extinct genus of large, mostly carnivorous bone-crushing mammals known as bear dogs, of the family Amphicyonidae found in Europe during the Late Oligocene and Early Miocene, in North America during the Early Miocene, and possibly in southwestern Africa during the Early Miocene.[1][2]

Taxonomy

Ysengrinia was named by Leidy (1853). was named by Ginsburg (1965). It was assigned to Amphicyoninae by Hunt (1998); and to Amphicyonidae by Ginsburg (1965), Carroll (1988) and Hunt (2002).[3]

Morphology

A single specimen was examined by Legendre and Roth for body mass and was estimated to weigh 71.6 kg (160 lb).[4]
