• "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
