Cohen proposed that Phoronida should be treated as a subphylum Phoroniformea within brachiopods (Cohen & Weydmann, 2005; Cohen, 2000, 2013; Santagata & Cohen, 2009). The primary unifying feature of the Lophophorata was the lophophore itself, a ciliated tentacular feeding structure, and the associated epistome.

Studies of molecular phylogenetics highlight how the three lophophorate phyla are allied with spiralian . Lophophorata is a clade composed of three Phyla: Phoronida, Brachiopoda, and Bryozoa. Brachiopods have SUPERFICIAL resemblance to bivalve molluscs (e. Some ancient brachiopod fossils from the species Lingulella have been used to define the beginning of the Cambrian period about 525 million years ago and are effectively identical to those of the living Lingula, which makes Lingula a true living fossil. Another common feature of the phylum is the radial cleavage pattern, which may confirm the close relationship between brachiopods and phoronids or represent a plesiomorphic state. , The phylum that includes snails, clams, oysters, and octopuses is the A.

While all molecular phylogeny studies and half the combined studies until 2008 conclude that brachiopods are lophotrochozoans, they could not identify which lophotrochozoan phylum were the closest relatives of brachiopods—except phoronids, which are a sub-group of brachiopods. Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Body Cavity 5. This ancient group of organisms has existed for at least 600 million years and constitutes the phylum Brachiopoda. The controversy lies due to their structural alliances with other groups of animals.
