Brachiopoda and Phoronida constitute a monophylum, Brachiozoa. The hypotheses that phoronids are the sister group of articulate or inarticulate brachiopods could be rejected by topology tests, thus confirming the monophyly of Brachiopoda. ...

The phylum Brachiopoda is divided into three subphyla: Linguliformea, Craniiformea and Rhynchonelliformea. Although they were extremely common throughout the Paleozoic, today they are considered a minor phylum, and only five orders have extant representatives: Lingulida, with two families, 6 ...Phylum Mollusca is the second largest phylum. A few molluscs such as Unio possess green glands which mimic the liver in vertebrates. They possess osphradia to test the chemical nature of water. The statocysts maintain body equilibrium. Octopus has 8 arms and contains no shell. They also possess ink glands for protection.Phylum Brachiopoda Rhynchotrema dentatum, a rhynchonellid brachiopod from the Cincinnatian (Upper Ordovician) of southeastern Indiana. Lampshells, brachiopods or "brachs," (not to be confused with the hard-shelled marine mollusks below) - 99% of all documented species of Brachiopoda are now extinct.lingulid, any member of a group of brachiopods, or lamp shells, that includes very ancient extinct forms as well as surviving representatives.First known from Cambrian rocks (about 542 million to 488 million years old), they probably originated during Precambrian time.The lingulids are small, inarticulate brachiopods; their shells are unhinged and consist of chitinous (fingernail-like) material.Brachiopods represent an animal phylum of benthic marine organisms that originated in the Cambrian. About 400 recent species are known from today’s oceans (Emig et al., 2013). Around 5000 fossil genera have been described, as brachiopods were dominant in the benthic marine environment during the Palaeozoic (Logan, 2007).

Brachiopods are probably unique among metazoans by having an excellent continuous fossil record dating ...history of the phylum: (1) identifying the origin, morphol-ogy and life modes of the first brachiopods; (2) under-standing the relationships of the major groups to each other and higher sister taxa; and (3) unravelling the roles of the Cambrian and Ordovician radiations that set the agenda for much of subsequent brachiopod evolution. SinceExternally brachiopods resemble bivalved molluscs in having two calcareous shell valves secreted by a mantle. They were, in fact, classed with molluscs until ...brachiopod: [noun] any of a phylum (Brachiopoda) of marine invertebrates with bivalve shells within which is a pair of arms bearing tentacles by which a current of water is made to bring microscopic food to the mouth — called also#R##N# lampshell.Linoproductus is an extinct genus of brachiopod bThe phylum Brachiopoda, more commonly call Brakiopoda, filum Brachiopoda, adalah hewan laut yang memiliki "katup" keras (cangkang) pada permukaan atas dan bawah, tidak seperti pengaturan kiri dan kanan di moluska bivalvia.Katup brakiopoda berengsel di bagian belakang, sedangkan bagian depan dapat dibuka untuk makan atau tertutup untuk perlindungan.

Arthropods are animals with a segmented body, external skeleton, and jointed appendages. The Arthropoda includes insects and crustaceans. Only two groups of arthropods are common as fossils in the Cretaceous of the C&D Canal area, and both are types of crustaceans: the Malacostraca (crabs, lobsters, and shrimp) and the ...Moss animal, any member of the phylum Bryozoa (also called Polyzoa or Ectoprocta), in which there are about 5,000 extant species. Another 15,000 species are known only from fossils. As with brachiopods and phoronids, bryozoans possess a peculiar ring of ciliated tentacles, called a lophophore, for.

Brachiopods belong to Phylum Brachiopoda, whereas bivalves belong to Phylum Mollusca, along with snails and cephalopods (e.g., octupuses and squids). (Learn more about bivalves here.) Defining Characteristics. Brachiopods: unequal valves (shell halves), lophophore, pedicle. Bivalves: mollusk (calcareous shell, mantle, gills), identical paired …The recently reinterpreted stem-group brachiopod Yuganotheca possesses a definitive functional pedicle, a horseshoe-shaped tentacular apparatus and a brachiopod-like bivalved shell with pinnate mantle canals and marginal chaetae , characteristics that do merit placement in the lophophorates and potentially as a stem-group brachiopod .Synonyms for phylum Brachiopoda in Free Thesaurus.
