Where: California (35.3° N, 119.6° W: paleocoordinates 35.3° N, 119.6° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• Pierce's sites 3 and 4 are younger than UCMP localities; all radiocarbon dates are in the range of 5-8 ka BP.

• bed-level stratigraphic resolution

Environment/lithology: tar; poorly lithified tar

Size class: macrofossils

Preservation: original chitin

Collected by Pierce in 1945; reposited in the LACM

• LACMIP loc 260 is equivalent to W. Dwight Pierce's SITE 3 and SITE 4, as well as L. Bessom's SITE 4. The locality was collected by Pierce et al. in October 1945 and again in November 1947.
