Parictis is the earliest genus of bear known. It was a very small and graceful ursid with a skull only 7 cm long. Parictis first appeared in North America in the Late Eocene (ca. 38 million years ago), but it did not arrive in Eurasia and Africa until the Miocene.[2] There is some suggestion that a limited emigration from Asia may have produced Parictis in North America due to the major sea level lowstand at ca. 37 Ma, however no Parictis fossils have yet to be found in East Asia.
