Shell Beds In The Upper Cretaceous Moreno Formation, California

An anonymous individual stands next to massive conglomeratic blocks in the upper Cretaceous portions of the upper Cretaceous to lower Paleocene Moreno Formation, south of Del Puerto Canyon, near the western edge of California's Great Central Valley. Those blocky conglomeratic layers contain prolific quantities of bivalve pelecypodal mollusks from the family Glycymeridae (genera Glycymeris and Glycimerita). About 70 million years old.
