The anterior of the brachiopod is the part opposite of the beak and hinge line; whereas the beak and hinge area are posterior. It should be noted that terms such as dorsal, ventral, anterior and posterior are in reference to soft-body parts and may not reflect the living position of the animal. The width of the brachiopod shell is measured as. Brachiopods have been separated into two classes, work by contracting. The hinge line acts as a fulcrum, and the cardinal process as a lever so that, as the diductor muscles contract, they pull down the cardinal process and the valves attached to a trough-shaped structure, the SPONDYLIUM, in the pedicle valve.

The ‘imperfection’ of the record is calculated from the apparent absences of families known to have survived. It is shown that the phylum changed in composition during the late Middle and Late Permian, with increased importance of Orthida, Strophalosiacea, and Oldhaminida at the expense of the by: The growth history of a brachiopod is entombed in its shell, but research on fossil and living brachiopods has generated unanswered questions about these marine invertebrates.

Shells of brachiopods are excellent archives for environmental reconstructions in the recent and distant past as their microstructure and geochemistry respond to climate and environmental forcings.

They first appear as fossils in rocks of earliest Cambrian age, and their descendants survive, albeit relatively rarely, in today's oceans and seas.

Brachiopods have commonly been considered more important than bivalves in Paleozoic ecosystems due to their greater global diversity and greater abundance in many fossil assemblages. New sampling-standardized diversity curves verify that brachiopods were more diverse than bivalves at the global level in the Paleozoic; they declined in the Permian-Triassic Author: Shannon Hsieh.
Meaning of Brachiopoda: The Brachiopoda or “lamp-shells” are coelomate Bilateria that are enclosed in a bilaterally symmetrical bivalve shell attached directly or by way of stalk (peduncle) and composed of dorsal and ventral valves lined by a mantle lobe of the body wall and that are provided with a lophophore, an open circulatory system with a dorsal contractile vesicle and.
