Skull and Skeletal Remains of a Ruminant of the Preptoceras-Euceratherium Group from the McKittrick Pleistocene, California

In studies of the Pleistocene mammalian assemblages of California the ruminant genera Preptoceras and Euceratherium have come to be regarded as characteristic of the faunas known from cave deposits of the State. Although the record of mammalian life at Rancho La Brea is unusually complete, it is noteworthy that no trace of these ungulates has been found. With continuation of excavations in the asphalt deposit of McKittrick, Kern County, situated between the occurrence in Los Angeles and the cave deposits of northern California, the discovery of remains of one of these ruminants by Mr. Charles H. Sternberg adds a new and important member to the list of mammals recorded from this horizon.
