LACMIP loc. 68-A, Newport Bay (Pleistocene of the United States)

Where: Orange County, California (33.6° N, 117.9° W: paleocoordinates 33.6° N, 117.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Palos Verdes Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• These are from the same exposure, but one station (locality 68-A) is about 8 to 10 feet lower in the section than the other (locality 68-B).

•The lower stratum is richly fossiliferous and near the Pliocene-Miocene contact.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified, fine-grained sandstone and unlithified, coarse-grained sandstone

• The sediments consist of fine grain sand near the top of the section and show a gradation from fine to coarse-grained sand towards the base. The Pleistocene sediments are only 12 to 18 feet thick at this exposure. The base level is reported by Mr. Thomas to be 82 feet (+ 1 foot).

Size classes: macrofossils, mesofossils

Reposited in the LACM

Collection methods: surface (float), surface (in situ),
