The Tejon Formation is a Paleogene period geologic formation in California.
The formation regionally overlies the Martinez Formation or the Chico Formation. [1] Paleontology in the Tejon Formation indicates a more tropical climate than during the Martinez Formation's period, with fauna that flourished in its littoral conditions. [1]
It is predominantly found in the Fort Tejon area of the San Emigdio Mountains and Tehachapi Mountains in Kern County, and around Martinez in Contra Costa County. [1]
Areas it surfaces, south to north, include: [1]
It preserves prehistoric plant and fauna fossils dating back to the Paleogene period of the Cenozoic Era. [2]
Species (1897 taxa names) found only in the Tejon Formation include: [1]
