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

• coordinate estimated from map

• local area-level geographic resolution

When: Timms Point Silt Formation, Middle Pleistocene (0.8 - 0.1 Ma)

• LITHOSTRATIGRAPHY: From what Crickmay (1929) considered the "Santa Barbara beds" [=Timms Point Silt]: AGE: Middle Pleistocene (~0.6-0.4 Ma) based on current understanding of the Timms Point Silt. STRATIGRAPHIC COMMENTS: Zone 4 is overlain by a deposit of fine yellow sand 40 feet thick, the base of which makes a sharp contact with the zone below. The lower 25 feet of this sand is zone 5. The upper 15 feet with many small concretions forms zone 6. In zone 5 the fossils are distributed evenly but very sparingly throughout, except for a 2-foot bed ap- pearing on the east side of the island 8 feet above the base in which shells of Thyasira disjuncta, with the two valves still together, are densely crowded.

• bed-level stratigraphic resolution

Environment/lithology: offshore; unlithified, fine-grained, yellow sandstone

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite
