Miocene bears

Ursavus is an extinct genus of bear that existed in North America, Europe, and Asia during the Miocene period, about 23–5.3 million years ago (Mya), existing for roughly . The genus apparently dispersed from Asia into North America about 20 Mya, becoming the earliest member of the subfamily Ursinae in the New World. Qiu points out that if a questionable 29 million-year-old specimen of Ursavus reported in North America is validated, Ursavus may have evolved in North America and dispersed westward into Asia. The higher number of fossils in Europe grading toward eastern Asia make t

Agriotherium is an extinct genus of bears whose fossils are found in Miocene through Pleistocene-aged strata of Eurasia and Africa. The earliest species, A. inexpetans, evolved during the Late Miocene, around 7.6 Mya. The latest record for the genus was around 1.8 Mya, during the Early Pleistocene.

Indarctos is an extinct genus of bear, present in Africa, North America, and Eurasia during the Miocene. It was present from ~11.1 to 5.3 Ma, existing for approximately .

Plionarctos is an extinct genus of short-faced bear endemic to North America from the Late Miocene to the Pliocene.

Cephalogale is an extinct genus of hemicyonine bear which lived in the Oligocene and Early Miocene epochs in North America and Europe. It lived from around 28.4—20.0 Mya. Before it was reconsidered to be close to the ancestry of hemicyonines, Cephalogale was once considered to be an ancestor of all bears.

Ursavini is an extinct tribe of mammals of the family Ursidae (bears) endemic to North America, Europe, Africa, and Asia during the Miocene through the Pliocene, living from about 23—2.5 Mya, existing for roughly 20.5 million years.

Ballusia was genus of small bear from the Early Miocene epoch, about 20.5-18 million years ago. Fossil remains attributed to the genus have been uncovered in Europe (Poland) and Asia (Russia, Mongolia, China). The genus Ballusia was established in 1998 on the basis of different fossils originally classified as various species of the genera Ursavus and Hemicyon, with B. elmensis as the type species. The exact relationship of Ballusia to "true" bears (subfamily Ursinae, which include modern bears) are not yet fully understood: many palaeontologists have classified it as a primitive member of Urs

Agriarctos is an extinct genus of panda from the Middle to Late Miocene, approximately 8-18 million years ago. This genus and its type species, A. gaali, was established based on fossils from Hatvan, Hungary, while A. vighi was based on fossils from Rózsaszentmárton. Miklós Kretzoi proposed that Agriarctos was closely related to Agriotherium. The previously published Ursavus depereti was assigned to Agriarctos by Kretzoi, but now proved to be polyphyletic.

Kretzoiarctos is an extinct bear genus from the European Miocene. It consists of Kretzoiarctos beatrix, an ancestor of the extant giant panda.
