Bivalve shell

Bivalves from the Cornbrash rocks of Dorset are usually quite poorly-preserved. But what is striking is how similar they are to the modern day cockle, Cardium. Bivalves are a very old and successful group. They were alive during the reign of the dinosaurs and survived the great Cretaceous-Tertiary extinction event.
