Amphicynodon is an extinct genus of mammal of the family Ursidae, endemic to Europe and Asia during the Oligocene, living from ~33.9—28.4 Mya, existing for approximately 5.5 million years.
Amphicynodon is a small basal member of Ursidae similar to early Mustelids in both size and existence.
Taxonomy
Amphicynodon was named by Filhol (1881). It was assigned to Phocoidea by McKenna and Bell (1997) then to Ursidae by Filhol (1881) and Hunt (1998); and to Ursidae also by Wang et al. (2005).[1][2]
