  The Lamp Shells (Phylum Brachiopoda)
The Brachiopoda, or Lampshells are an ancient phylum of filter feeding marine worms.
However even though the Brachiopoda appear to have evolved earlier than the bivalves, they were quite a diverse group by the beginning of the Cambrian 600 mya (million years ago), where as the bivalves didn't really get started for another 50 to 100 million years.
Taxonomically the Brachiopoda are divided into two major groups, the Articulata and the Inarticulata on the basis of the shell structure.

Brachiopoda (lamp shells) A phylum of solitary, marine, bivalved, coelomate invertebrates that live attached to the seabed by a muscular stalk (pedicle), or are secondarily cemented, or are free-living.
Acrotretida (phylum Brachiopoda, class Inarticulata) An order that comprises two suborders of brachiopods which are usually circular or semicircular in outline.
Inarticulata (Ecardines; phylum Brachiopoda) A class of brachiopods whose chitinophosphatic or calcareous valves are held together only by muscles and the body wall, and not hinged.

Protremata (Beecher).Articulate Brachiopoda, with pedicle-opening restricted to ventral valve, and either open at the hinge line or more or less completely closed by a pseudo-deltidium, which may disappear in adult.
Telotremata (Beecher).Articulate Brachiopoda, with the pedicle-opening, confined in later life to the ventral valve, and placed,at the umbo or beneath it.

 Encyclopedia: Brachiopoda
The phylum most closely related to Brachiopoda is probably the small phylum Phoronida (known as "horseshoe worms").
Since most orders of brachiopods have been extinct since the end of the Paleozoic Era, classifications have always relied extensively on the morphology (that is, the shape) of fossils.

The name brachiopoda (brachio = arm, pod = foot), refers to internal paired appendages (brachia or lophophore) which at first were assumed to function for locomotion, like the foot of mollusks.
The brachiopoda are chiefly inhabitants of the shallow sea bottom and they live in a fixed position (sessile).
Most inarticulate brachiopoda have hard parts composed predominantly of calcium phosphate and chitinous organic matter, such shells are termed chitinophosphatic.

Brachiopods are organisms that superficially resemble Bivalve Molluscs, but the difference lies in their external shell, which has two valves, one of which is dorsal and the other ventral, instead of them being lateral and symmetrical.
All the living Brachiopoda are marine, solitary, and usually attached to the substratum by a fleshy peduncle emerging from a hole in the rear part of the ventral valve.
