Bivalve
Chesapecten
Chesapeake scallop
Chesapecten is the large Miocene–Pliocene scallop of Chesapeake Bay and the Carolinas, up to 20 cm across, and Virginia's state fossil (C. jeffersonius). Whole valves from Calvert Cliffs, the Yorktown beds and Lee Creek are common and cheap; matched pairs with barnacles are attractive. It is a good index fossil for the Chesapeake Group.
