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

• coordinate estimated from map

• outcrop-level geographic resolution

When: Palos Verdes Sand Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• LITHOSTRATIGRAPHY: From the so-called "Pliocene" layer of Dall (1892), which likely equates to the upper San Pedro Series of Arnold (1903), based on the locality description of Ashley (1895), which appears to refer to Crawfish George, an outcrop of the Palos Verdes Sand. VERBATIM STRATIGRAPHIC COMMENTS: The fossiliferous beds on the flanks of the hill [San Pedro Hill] were called by Conrad "recent or post-Pliocene", and "Quaternary" by Cooper (1888). In 1892, in the correlation paper on the Neocene, Dall (1892) says "it appears that on Deadman Island, near Point Fermin, at least three distinguishable strata appear, the uppermost of which is certainly Pleistocene, while the others are Neocene, and the middle layer probably Pliocene. As Deadman Island is, in all probability, only an outlier of San Pedro Hill, the middle layer on the hill may be incleded as referred to the Pliocene by Dr Dall.This is the state of things as recognized by Prof. Lawson, who on that basis assigns the middle layer on San Pedro Hill to the Pliocene". AGE: Late Pleistocene (~.125 Ma) based on current understanding of the Palos Verdes Sand. STRATIGRAPHIC RESOLUTION: List is exhaustive of the Palos Verdes Sand in a relatively small outcrop, so given stratigraphic resolution of group of beds.

• group of beds-level stratigraphic resolution

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

Size classes: macrofossils, mesofossils, microfossils

Preservation: original aragonite, original calcite

Collected by G. Ashley; reposited in the CAS

• COLLECTOR: Not explicitely stated, but it is believed to have been collected by G.L. Ashley, in the early 1890s. REPOSITORY: Not stated, but probably at either Leland Stanford Junior University [=Stanford] or the California Academy of Sciences. In either case the collection likely resides at CAS unless destroyed.
