The photos above show a view of the Calvert Cliffs State Park on the western shore of the Chesapeake Bay in Maryland and two views of bivalve deposits on the beach fronting the Bay. Marine deposits along the Chesapeake Bay and its tributaries contain numerous Miocene fossils. The clay and sand sediments composing the cliffs readily slump into the Bay waters, as evidenced by the trees and driftwood along the shore, and waves eventually wash out mollusks, sharks' teeth and both marine and land mammal bones. These cliffs are a treasure trove for shark's teeth. Photo taken on March 19, 2011.
