"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.cite book | author = Kemp, T.S. | year = 2005 | title = The Origin and Evolution of Mammals | publisher = Oxford University Press | id = ISBN 0198507607] 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 yet to be found in East Asia.
