Abstract: The first recorded collection of fossils from the Pittsburg Bluff Formation was identified by W. H. Dall in 1896 and was assigned to the Oligocene. This was the first marine fauna on the Pacific coast to be assigned to the Oligocene. Although the fauna was briefly regarded as Eocene in the early 1900's, it has since been referred to the Oligocene, then more precisely to the middle Oligocene, an assignment that still stands.
