Cephalogale is an extinct genus of bear-like hemicyonid carnivores of the late Oligocene through Miocene epochs, endemic to North America and Europe living from around 33.9—20 Mya, existing for about 33.9-20 million years.
Before it was reconsidered to be close to the ancestry of hemicyonids, Cephalogale was once considered to be an ancestor of all bears.[1]
Taxonomy
Cephalogale was named by Henri Filhol in 1879. Its type is Cephalogale geoffroyi. It was assigned to Ursidae by Carroll (1988); to Hemicyoninae by Hunt (1998); and to Ursoidea by Wang et al. (2005).[2][3]
