Cephalogale is an extinct genus of hemicyonid ursid which appeared in 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]
