The soft parts of brachiopods are covered with a shell made of two valves that vary in size and chracteristics. The two valves are held together in two distinct ways that led to differentiation of brachiopods ... The Brachiopoda, (or Lamp Shells) are an ancient phylum of filter feeding marine worms. They live inside a pair of shells, much like the more numerous bivalves. However, they are no more related to bivalves than people are to starfish! Brachiopods differ from bivalves in many ways, but perhaps the easiest to see is in their shells.Lamp shells - Fossilization, Mollusks, Brachiopods: Brachiopods were among the first animals to appear at the beginning of the Cambrian Period. They possess a lophophore, excretory organs (nephridia), and simple circulatory, nervous, and reproductive systems.

definition of Brachiopoda (Williams et al. 2000) presents something of a paradox: Of all the many features used to define the phylum, only the presence of a bivalved, bilaterally symmetrical organophosphatic or organocarbonate shell can be preserved with fidelity in the fossil record, which records fully 95% of brachiopod diversity. Brachiopods (from the Greek, meaning “arm-foot”), also known as lamp shells or the “other” bivalves, have played a central role in both geologists’ and biologists’ understanding of the history and evolution of life on Earth.This Phylum has a low diversity, with 4.2 % of the total species found in this study.
