Deadman Island area - Lower San Pedro Series (1900s-1950s) [San Pedro Sand] (Pleistocene of the United States)

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

• coordinate estimated from map

• local area-level geographic resolution

When: San Pedro Sand Formation, Middle Pleistocene (0.8 - 0.1 Ma)

• LITHOSTRATIGRAPHY: From the lower part of the San Pedro Series [=San Pedro Sand]: AGE: Middle Pleistocene (~0.3 Ma) based on current understanding of the San Pedro Sand. STRATIGRAPHIC RESOLUTION: List is exhaustive of the San Pedro Sand in a relatively small geographic area, so given stratigraphic resolution of formation.

• formation-level stratigraphic resolution

Environment/lithology: coastal; unlithified, shelly/skeletal sandstone

• ENVIRONMENT: Not stated, but based on current understanding of the units likely collected the list represents nearshore through inner shelf, siliciclastic depositional settings.

• SPECIFIC LITHOLOGY: Unknown, but based on likely collecting localities would have likely comprise sand and possibly conglomerate. LITHIFICATION: Unknown, but based on likely collecting localities would have been unlithified.

Size classes: macrofossils, mesofossils, microfossils

Preservation: original aragonite, original calcite

Collection methods: COLLECTOR: Multiple collectors including R. Arnold, M. Williamson, and others. REPOSITORY: Multiple repositories including CAS, LACMIP, SBMNH, and UCMP.
