Artiodactyla from the Sespe of the Las Posas Hills, California

The artiodactyla found at the Kew Quarry site in the Sespe deposits of the Las Posas Hills, Ventura County, California, comprise at present three forms, namely a camelid, the genus Hypertragulus, and possibly a bothriodont. This assemblage is again noteworthy in furnishing information of value in establishing the relationships o the Kew Quarry fauna to the John Day and White River faunal stages. At least one of these recorded forms from the Upper Oligocene extends considerably the known geographic distribution in North America of the particular group to which it belongs.
