Brachiopods phylum.

The phylum Brachiopoda, or lamp-shells, consists of roughly 400 living and more than 12,000 fossil species of benthic, marine organisms. Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Molecular studies almost unanimously show Brachiopoda as a monophyletic group. Brachiopods are animals that live inside two shells (or valves) that show bilateral symmetry from side to side (i.e., if viewed from above or below). The top and bottom shells are not the same shape. To see this, look at the Side view in Figure 7.9: the valve on the left is the top and the valve on the right is the bottom. L. waikatoensis Pen, 1930. Synonyms. Ligula, Ligularius, Lingularius, Pharetra. Lingula is a genus of brachiopods within the class Lingulata. Lingula or forms very close in appearance have existed possibly since the Cambrian. Like its relatives, it has two unadorned organo-phosphatic valves and a long fleshy stalk. Download to read offline. Education.

Brachiopods ( / ˈbrækioʊˌpɒd / ), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.Brachiopods are a phylum of animals that originated from the Cambrian period and had its maximum splendor until the Ordovician. At present they are considered as a vestigial group; there are only about 335 known species.

The late Bashkirian faunal assemblage from Mina Profunda consists of skeletal parts of benthic organisms (e.g., brachiopods, echinoderms, bryozoans) along with nektonic elements (conodonts, sharks).

Brachiopoda, phylum of bivalved marine invertebrates, sometimes called lamp shells.
