Where: Orange County, California (33.7° N, 117.6° W: paleocoordinates 35.0° N, 81.9° W)

• coordinate estimated from map

When: Holz Member (Ladd Formation), Late/Upper Turonian (93.5 - 89.3 Ma)

• The boulder was found loose on the ground among oak trees about fifty feet west of a fence line crossing the road and thirty feet below beds of fossiliferous sandstone and conglomerate north of the road. Owing to the slope of the hillside, the loose boulder seems to have come from the zone of fossiliferous strata. These strata contain abundant specimens of Tiirritella chicoensis Gabb, 1864, and Glycymeris veatchii (Gabb), 1864, and comprise a lens in the Holz Shale Member of the Ladd Formation of Late Cretaceous age (Chico Epoch).
