The Clam field of the Fossils section should be used to record any observation of a fossil clam. For purposes of the CCNP Cave Inventory Form, a clam refers to any bivalve mollusk that is not a brachiopod.
Clams and brachiopods are superficially similar. They both have a shell consisting of two valves. In brachiopods, the two valves are on the dorsal and ventral surfaces of the body, while in clams, they are on the left and right sides. Other than their superficial similarities, they are not really related.
Clams and brachiopods are sometimes difficult to distinguish.
