They are often known as “lamp shells”, since the curved shells of the class Terebratulida look rather like pottery oil-lamps.Brachiopods are marine animals that, upon first glance, look like clams. They are actually quite different from clams in their anatomy, and they are not closely related to the molluscs. They are lophophorates, and so are related to the Bryozoa and Phoronida. Although they seem rare in today's seas, they are actually fairly common. A Modern Day Brachiopod. Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell.White, C. A., and St. John, O. H., 1867, Description of new Subcarboniferous and coal measure fossils collected upon the geological survey of Iowa, together with a notice of new generic character observed in two species of brachiopods: Academy of Sciences of Chicago Transactions, v. 1, p. 115-127.

The similarity in their appearance is the result of ... Brachiopods are benthic (bottom dwelling), marine (ocean), bivalves (having two shells). They are considered living fossils, with 3 orders present in today’s oceans. They are rare today but during the Paleozoic Era they dominated the sea floors. Though they appear to be similar to clams or oysters they are not related. They are not even mollusks. Brachiopods. Brachiopods are rare in modern oceans, but were very common in the past (only 325 living species but more than 12,000 fossil species).

Abundant in the fossil record, Darwin first referred to lingulid brachiopods as ‘living fossils,’ because their ...To date, studies of Paleozoic brachiopod biogeography have no strong theoretical base; rather the various numerical techniques available, including both cladistic and phenetic methodologies, have helped organize the growing amount of distributional data into recognizable and useful structures. Type.The name “brachiopod” is from Latin brachium for “arm” and ancient Greek pod for “foot.” The name was inspired by the two “arm” branches of the lophophore and its calcareous support structure, which is occasionally preserved as a fossil. Brachiopods lived free or attached on top of the seafloor or within seafloor sediments The dominance of Paleozoic articulate brachiopods in once-muddy environments may be explained by an array of mechanisms and structures that reject nonfood particles, in some cases without interruption of feeding: (1) behavioral flexibility of the lophophore and its individual filaments; (2) persistent, variable-speed rejection currents on the mantle, which …Trammel Fossil Park.
