Locality D-1063 - Reef Ridge (Temblor Formation) (Miocene of the United States)

Also known as D-1063

Where: Fresno County, California (35.9° N, 120.2° W: paleocoordinates 35.2° N, 115.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Sandstone bed with a conglomerate layer at its base. The basal portion of this bed (approx. 8 inches) is richly fossiliferous. Some sandy concretions immediately above this bed also contain a few fossils. From faunizone B (zone 4) (for that reason assigned an middle Miocene age).

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, brown, blue, silty, conglomeratic sandstone and concretionary, sandy siltstone

• 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.
• Predominantly blue-brown silty sandstone bed with a thin, conglomerate layer. Fossils also from massive spheroidal sandy siltstone concretions.

Size class: macrofossils

Reposited in the UCMP

Collection methods: quarrying,

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