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. From Crickmay (1929) - It permits a tentative correlation of these shales with the formation which crops out along the coast from San Pedro to Point Fermin. These have been supposed to be of Miocene age, though it must be confessed there is very little reason for that correlation. The dating of these beds, and the estimation of the hiatus between them and the Santa Barbara formation, should be regarded as problems. STRATIGRAPHIC RESOLUTION: From Zone 2, a layer of hard gray shale which weathers to a rusty yellow.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, gray shale

Size class: macrofossils

Preservation: original aragonite, original calcite
