Craniata (brachiopod)

provided by wikipedia EN

Craniata is a class of brachiopods originating in the Cambrian period and still extant today.[1] They have calcitic inarticulated shells that are subcircular in outline. This class of brachiopods has an unsupported lophophore and is always attached to a hard substrate in the fossil record. This hard substrate is usually another brachiopod. The plicae from the host brachiopod will then appear within the shell of the craniata.[2]

Craniata is the only class within the subphylum Craniiformea. The class Craniata is divided into three orders, one of which is still extant (Craniida).
