Brachiopods phylum
Members of the phylum Brachiopoda, commonly called ‘lamp shells’, are bivalved lophophorate invertebrates, recognized by a distinctive combination of mineralized and nonmineralized morphological features of their shell (Carlson, 2016). Brachiopods are probably unique among metazoans by having an excellent continuous fossil record dating ...Introduction. Lophotrochozoa is a monophyletic group of animals that includes annelids, molluscs, bryozoans, brachiopods, platyhelminthes, and other animals that descended from the common ancestor of these organisms. Lophotrochozoa is one of the three major clades that comprise bilateral animals, or Bilateria.
