Locality D-1055 - Reef Ridge (Temblor Formation) (Miocene of the United States)

Also known as D-1055

Where: 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)

• From top of same massive silty sandstone bed as D-1054, about 20 ft stratigraphically above D-1054. From faunizone A (for that reason assigned an early Miocene age).

• bed-level stratigraphic resolution

Environment/lithology: coastal; fine-grained, brown, silty 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.
• Massive silty sandstone.

Size class: macrofossils

Reposited in the UMMP

Collection methods: quarrying,

• Collected by Adegoke. Collections reposited in UCMP.
