Brachiopod. Brachiopods (/ ˈbrækioʊˌpɒd /), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.
Paraspirifer. Paraspirifer is a genus of large brachiopods (up to about 7.5 centimetres or 3.0 inches) that lived during the late Lower and Middle Devonian in what now are Germany, Spain, Morocco and the United States (New York State and Ohio).
Palaeontology portal; Rhynchonella is an extinct genus of brachiopod known from the Late Jurassic to the Early Cretaceous (Valanginian, possibly Barremian). [1] Formerly [2] this genus was understood much more widely (more or less an equivalent of the Rhynchonellida order in the present-day taxonomy) and less critical sources still list species of Rhynchonella from the Ordovician to the Eocene.

This is a list of brachiopod genera which includes both extinct (fossil) forms [1] and extant (living) genera (bolded). [2] Names are according to the conventions of the International Code of Zoological Nomenclature .
The Craniidae are a family of brachiopods, the only surviving members of the subphylum Craniiformea.They are the only members of the order Craniida, the monotypic suborder Craniidina, and the superfamily Cranioidea; consequently, the latter two taxa are at present redundant and rarely used.There are three living genera within Craniidae: Neoancistrocrania, Novocrania, and Valdiviathyris.

L. waikatoensis Pen, 1930. Synonyms. Ligula, Ligularius, Lingularius, Pharetra. Lingula is a genus of brachiopods within the class Lingulata. Lingula or forms very close in appearance have existed possibly since the Cambrian. Like its relatives, it has two unadorned organo-phosphatic valves and a long fleshy stalk.
Species. T. terebratula (Linné, 1758) (type) = Anomia terebratula. Terebratula is a modern genus of brachiopods with a fossil record dating back to the Late Devonian. These brachiopods are stationary epifaunal suspension feeders and have a worldwide distribution.
