The Tejon Formation is a Paleogene period geologic formation in California.

Geology

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]

Occurrences

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]

Fossils

It preserves prehistoric plant and fauna fossils dating back to the Paleogene period of the Cenozoic Era.[2]

Species

Species (1897 taxa names) found only in the Tejon Formation include:[1]
