The Calvert Cliffs on the western shore of the Chesapeake Bay in Calvert County are justly famous as a fossil collecting area. The fossiliferous deposits belong to the Chesapeake Group of Miocene age geological strata in the Atlantic Coastal Plain region. These deposits are exposed in cliffs up to 100 feet high between Chesapeake Beach and Drum Point and constitute the most complete section of Miocene deposits in the eastern United States. The Chesapeake Group is divided into three formations. The oldest, the Calvert Formation, is composed of diatomaceous earth and dark sandy clays and marl. It is overlain by the yellowish sand and greenish clay and marl of the Choptank formation.
