Amphicyoninae is a subfamily of extinct Amphicyonidae, large terrestrial carnivores (bear-dogs) belonging to the suborder Caniformia (meaning "dog-like") and which inhabited North America, Europe, Eurasia, Asia. and Africa from ~22.4—4.9 Ma. Amphicyoninae existed for approximately ~17.5 million years.[1]
Amphicyoninae was named by Trouessart (1885). It was assigned to Canidae by Matthew (1902); to Ursidae by Ginsburg (1977); and to Amphicyonidae by Hunt (1998).[2][3][4]
