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[edit]

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]
