They were extremely diverse during the Devonian period and later went extinct during the Jurassic period. Some fossil brachiopods make spectacular finds, like this one preserved as pyrite (fools gold).Brachiopods flourished in neritic environments that were unfavourable for conodonts and ammonoids. In the absence of the latter traditional marker fossils, they are potentially important for locating the Devonian–Carboniferous boundary in shallow water depositional settings in conjunction with rugose corals and foraminifers.Jul 7, 2009 · Articulate brachiopods are known to depend on ambient fluids for their feeding and respiration under certain circumstances (e.g., Rudwick, 1970; James et al., 1992; LaBarbera, 1977, LaBarbera, 1981, LaBarbera, 1984). These ecological features strongly suggest that a function of the brachiopod shell is to direct the The number of brachiopod genera discovered and named since 1965 has more than doubled the approximately 1700 genera described in Part H of the Treatise on Invertebrate Paleontology (Williams and others, 1965). 4827 genera and subgenera named as of 1995 are listed in Doescher (1996); it is likely that over 5000 exist by now.

Platyceratid gastropods, found at the same locality as these brachiopods, are the most likely drilling organism. Previous reports of Paleozoic brachiopod parasitic traces can be classified into two main groups, constructive association and destructive association, depending on whether parasites damage brachiopod shells.

The filter-feeding organ of some extinct brachiopods is supported by a skeletal apparatus called the brachidium.

To investigate the variations of brachidial morphology in Spiriferida, 65 species belonging to ...Open-ended tubes were found extending inward from the inner surfaces of brachial valves of three different species of Emsian spiriferid brachiopods. It is believed that these tubes were formed by the outer epithelium of the brachiopods, precipitating shell material around a small commensal filter feeding organism living in the outer mantle cavity.Microstructure of the shell of a Permian Spiriferid brachiopod Journal of the Geological Society of Australia (1968) Bion H.S.

Spiriferid are brachiopods filtering feeders that fed on organic particles washed around by the ocean currents. The valves (each shell side) has pronounced folds and sulcus (furrow, fissures). They lived in mud by anchoring to the sea floor with a fleshy stalk called a pedicle that protruded from the shell’s hinge.

BHL operates as a worldwide consortium of natural history, botanical, research, and national libraries working together to digitize the natural history literature held in their collections and make it freely available for open access as part of a global "biodiversity community." In the extant articulate brachiopods, the tentacles of the lophophore lack supporting structures such as muscle fibres or bones (Reed & Cloney, 1977; Williams, 1997a).
