A new classification of the Brachiopoda is proposed to take into account recent advances in our understanding of the anatomy, shell morphology, ontogeny and phylogeny of the phylum.

Lingula eg.lophophorate, any of three phyla of aquatic invertebrate animals that possess a lophophore, a fan of ciliated tentacles around the mouth.

Brachiopoda - Invertebrate Paleontology | GEO GIRLThe Devonian brachiopod Tylothyris from the Milwaukee Formation, Milwaukee County, Wisconsin. The origin of the brachiopods is uncertain; they either arose from reduction of a multi-plated tubular organism, or from the folding of a slug-like organism with a protective shell on either end. Since their Cambrian origin, the phylum rose to a Palaeozoic …

This indicates that brachiopods and phoronids together form sister groups at the base of all other lophotrochozoan phyla. 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.
