The occurrence of bothriodontines (Artiodactyla, Mammalia) in the Paleogene of Asia with special reference to Elomeryx: Paleobiogeographical implications

摘要

Anthracotheriid remains from several Paleogene localities of central and eastern Asia have been re-examined. Several fossil remains attributed to the genera Bothriodon, Brachyodus and Hyoboops can be referred to Elomeryx which extends the geographical distribution of the genus to the whole area of Asia. These results demonstrate the role that Asia played in the biogeographical history of mammals and further support the proposed origin of North American Elomeryx from an Asian ancestor.
