Brachiopods are more closely related to Bryozoans than Mollusks. The easiest differences to identify are in the shells of clams and Brachiopods. Mollusk shells are divided into left and right while Brachiopod shells are divided top (dorsal) and bottom (ventral). The shells of mollusks are usually equal on the right and left.

The base of the colony shows concentric undulating growth bands 20–50 mm apart, that on closer examination are subdivided by finer bands 2–5 mm apart.Based on fluid mechanical considerations, a mode of life for the spiriferid Austrospirifer variabilis Glenister is presented. This palaeoecological model suggest that, in an environment where the water currents were at least of the order of 0.5 m/s. the spiriferid, anchored to the substrate by its pedicle, flew in the water in much the same way as a kite flies in air.

In this work we discuss the results of ontogenetic and morphobiological approaches to phylogenetic reconstructions of articulate brachiopods on the basis of morphogenetic data. These data provide the basis for generalizations concerning phylogeny and system of orders. The ontogenetic approach was the subject of criticism mainly because of arbitrary establishment of the homology of brachiopods ...

To avoid deflection of tentacles by water flow, a slower internal flow appears to have preferred for feeding in articulate brachiopods (LaBarbera, 1977; Dhar et al., 1997). from, e valves of spiriferid brachiopods. Th tubes are the product of a disrupted outer epithelium. They Erejected inward into the outer mantle cavities of the rachiopods and were apparently caused by the presence of a small commensal filter feeding organism. The ends of these tubes open in between the bases of the two spires of the brachiopod.ABSTRACT Minute, lamellose concentric micro-frills are described on the external surfaces of the Devonian brachiopod Athyris campomanesi (Verneuil & Archiac). The micro-frills are very regularly spaced with a separation of approximately 0.5 mm, are inclined anteriorly and antero-laterally, and become more or less recurved peripherally down towards the valve surface. These micro-frills must ...This is a very large spiriferid brachiopod fossil. It looks like a large, more robust, version of M. audaculus. It is very rounded, and the hinge line is not straight, but is slightly concave. It's called spinocyrtia because of fine spines (almost like tiny hairs) that cover the brachiopod. These spines are only preserved on exceptional specimens.

Articulate brachiopods, which have a blind intestine, may depend partly on dissolved nutrients. Shells of some articulate brachiopods have a fold, which forms a trilobed anterior that helps keep lateral, incoming food-bearing currents separated from outgoing, waste-bearing currents.Archiacoceras inversum, Onyxites sp. and Discosoridae indet.; inarticulate brachiopod valves of the lingulid type, rhynchonellid brachiopods Ripidiorhynchus ex gr. livonicus, spiriferid brachiopods Cyrtospirifer biloviensis; phyllocariid crustaceans Echinocaris tudrensis; ostracods Cryptophyllus socialis; unidentifiable microconchs …A moderately diverse Permian brachiopod fauna is described from a new rock unit, the Bera Formation, in the Bera District, central Pahang, Peninsular Malaysia.
