LACMIP Loc. 1310 (Pleistocene of the United States)

Also known as Marincovich Site 5-2

Where: Los Angeles County, California (33.7° N, 118.3° W: paleocoordinates 33.7° N, 118.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• LITHOSTRATIGRAPHY: From unnamed Quaternary terrace, which locally overlies Altamira Shale (middle-late Miocene). AGE: Late Pleistocene, following Marincovich (1976). STRATIGRAPHIC DETAILS: From terrace five of Woodring et al. (1946).

• bed-level stratigraphic resolution

Environment/lithology: shoreface; unlithified siliciclastic sediments

• ENVIRONMENT: fauna is characteristic of rocky intertidal or shallow subtidal hard ground. SEQUENCE STRATIGRAPHY: from terrace deposit accumulated under transgressive conditions.
• LITHOLOGY: not reported in text, but siliciclastic. LITHIFICATION: not reported in text, but fossils in LACMIP collection from LACMIP loc. 1309 are unlithified.

Size class: macrofossils

Preservation: original aragonite, original calcite

Collected by W. Easton & L. Marincovich; reposited in the LACM

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

• COLLECTOR: W. Easton and L. Marincovich (c. 1970s). REPOSITORY: LACMIP, including former USC collections.
