Schoonover, 1941, p. 201. «Discussion.— Eburneopecten cerinus (Conrad) is a small, smooth form which is common in Bed 10 of the Plum Point Marl Member of the Calverr Formation. It may be a member of a lineage that started in the Paleocene and is well represented as late as the late Oligocene in South Carolina. No pectinids of this genus are known in the Miocene to Pliocene beds stratigraphically higher than Bed 10.
