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: Zone 3 passes by gradual transition into zone 4, a deposit of very fine silt or clay densely charged with fossils. These fossils, mostly small, even microscopic, are extremely numerous, there being several million to the cubic foot. They are distributed patchily, though thickest in the middle part of the zone. This zone is 12 feet thick on the west side of the island, but thins down to 7 feet on the east.
