Ysengrinia is an extinct genus of large, mostly carnivorous bone-crushing mammals known as bear dogs, of the family Amphicyonidae found in Europe and 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]
