Locality B-7085 - Coalinga Anticline (Temblor Formation) (Miocene of the United States)

Also known as B-7085

Where: Frensno County, California (36.3° N, 120.4° W: paleocoordinates 35.6° N, 116.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Temblor Formation, Middle Miocene (16.0 - 11.6 Ma)

• Collection from a "button" bed near the top of the hill. From faunizone B (zone 3) (for that reason assigned an middle Miocene age).

Environment/lithology: coastal; sandstone

• Deposited in partially enclosed bay. The fauna has a preponderance of shallow-water forms and many of the genera are characteristic of tropical or subtropical climate.
• No lithological data reported, but probably sandstone.

Size class: macrofossils

Reposited in the UCMP

Collection methods: quarrying,

• Collected by O. Adegoke. Collectetions reposited at UCMP.
