The brachiopods are marine to brackish water bivalves which still exist today although in greatly reduced numbers. The brachiopods were at their peak during the Ordovician. Brachiopods come in two varieties, the articulates and the inarticulates. The articulates are more advanced and more interesting.With very few living representatives, brachiopod classification has primarily come from a paleontological perspective, with substantial consideration given to the morphology of the shell. Traditionally, brachiopods have been separated into two major groups: the Inarticulates (brachiopods with phosphatic shells) and Articulates (everything else).
