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.^[1] There is some suggestion that a limited emigration from Asia may have produced Parictis in North America due to the major sea level lowland circa 37 mya; however, as yet no Parictis fossils have been found in East Asia.
