Scallops
Scallops (Pectinidae: Pecten, Argopecten, Chlamys, Mimachlamys and others) are the fan-shaped bivalves with radial ribs and ear-like auricles that swim by clapping their valves; the great scallop Pecten maximus is the pilgrim's badge, and the Pacific 'lion's paw' Nodipecten nodosus and the coloured Mimachlamys are collector species. Scallops are among the most common fossils in Cenozoic beds (Chesapecten, Carolinapecten). Matched pairs are worth more than single valves.
