Amphicyonidae

Amphicyonidae is an extinctfamily of terrestrialcarnivorans belonging to the suborderCaniformia. They first appeared in North America in the middle Eocene (around 45 Ma), spread to Europe by the late Eocene (35 Ma), and further spread to Asia and Africa by the early Miocene (23 Ma). Amphicyonids were among the first lineages of carnivorans to reach large body sizes. The family had largely disappeared worldwide by the late Miocene (9-7 Ma), with the latest recorded species at the end of the Miocene in Africa. Amphicyonids are colloquially referred to as "bear-dogs".
