Title: The Vertebrate Paleontology of the Sespe Formation: ABSTRACT

Author(s): Chester Stock

Article Type: Meeting abstract

Abstract:

The three principal areas from which vertebrate faunas have been obtained in the Sespe are north of the Simi Valley, Las Posas Hills, and South Mountain, California. At least four stages in the history of North American mammal life are known from the Sespe and these range in age from Upper Eocene to Lower Miocene. Their correlatives in the Cordilleran, Great Basin, and Great Plains provinces appear to be (1) Uinta, (2) post-Uinta or pre-White River, (3) Upper White River, and (4) Upper John Day or Lower Rosebud.
