Also known as USGS 12203; W4-30
Where: Los Angeles County, California (33.7° N, 118.3° W: paleocoordinates 33.7° N, 118.3° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Timms Point Silt Formation, Middle Pleistocene (0.8 - 0.1 Ma)
• LITHOSTRATIGRAPHY: From the Timms Point Silt, which is locally overlain by the San Pedro Sand; it is possible that this is infact from the San Pedro Sand. AGE: Lower Pleistocene in Woodring et al. (1946) and Valentine PhD, but is now regarded as Middle Pleistocene [A. Hendy]. STRATIGRAPHIC POSITION: From Unit 1 (?) of Timms Point Silt.
• bed-level stratigraphic resolution
Environment/lithology: offshore; poorly lithified siltstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite, original calcite
Collected by W. Woodring in 1930; reposited in the USGS, USNM
