Rancho La Brea, Pit Bliss 29 (LACMIP 277) (Pleistocene of the United States)

Where: Los Angeles County, California (34.1° N, 118.4° W: paleocoordinates 34.1° N, 118.4° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Rancholabrean (0.3 - 0.0 Ma)

• "These excavations all included a Late Pleistocene biota, but assignment of exact ages is impossible in most cases because most of the Pierce beetle specimens are without stratigraphic data."

• group of beds-level stratigraphic resolution

Environment/lithology: tar; poorly lithified tar

Size classes: macrofossils, mesofossils

Reposited in the LACM
