Also known as D-1056

Where: Frensno County, California (35.9° N, 120.2° W: paleocoordinates 34.9° N, 114.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Temblor Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• Locality is approx. 20 ft below the lower oyster bed of locality D-1057. From faunizone A (zone 2) (for that reason assigned an early Miocene age).
