Bivalve

This ironstone block contains Cardita planicosta, and other bivalves with Turritella and Cerithium gastropods (snails). As the name suggests, bivalves consist of two shells. ‘Bi’ means two and ‘valve’ means shell. The shells are held together by a strong muscle, and hinged at the pointed end.
