Crurithyris is an extinct genus of brachiopod belonging to the order Spiriferida and family Ambocoeliidae. [1] [2]
Thomas Davidson was a British palaeontologist.
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. As adults, craniids either live freely on the ocean floor or, more commonly, cement themselves onto a hard object with all or part of the ventral valve.
Acrotretides (Acrotretida) are an extinct order of linguliform brachiopods in the class Lingulata. Acrotretida contains 8 families within the sole superfamily Acrotretoidea. They lived from the Lower Cambrian to the Middle Devonian, rapidly diversifying during the middle Cambrian. In the upper Cambrian, linguliforms reached the apex of their diversity: acrotretides and their relatives the lingulides together comprised nearly 70% of brachiopod genera at this time. Though acrotretides continued to diversify during the Ordovician, their proportional dominance declined, as rhynchonelliforms took on a larger role in brachiopod faunas.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2014.

Mesolobus is an extinct genus of brachiopod belonging to the order Productida and family Rugosochonetidae.
Phestia is an extinct genus of clam belonging to order Nuculanida and family Nuculanidae.
Schizophoria is an extinct genus of brachiopod belonging to the superfamily Enteletoidea. Specimens have been found in Devonian through Permian beds in North America, Australia, central and southeast Asia, and eastern Europe.
Leiorhynchus is an extinct genus of brachiopod belonging to the order Rhynchonellida and family Leiorhynchidae. Specimens have been found in South America, North America, and Russia in beds of middle Devonian to Mississippian age. The genus may have been adapted to dysaerobic environments, colonizing areas of reduced oxygen concentrations rich in organic matter. The genus has been used as an index fossil in North America.
Beecheria is an extinct genus of brachiopod belonging to the order Terebratulida and family Beecheriidae. Fossils of this genus have been found in Mississippian to Permian beds in Eurasia, Australia, North America, and South America. The genus was part of the Levipustula fauna characteristic of cold water conditions. "Nests" of Beecheria have been found in fossil low temperature hydrothermal vent communities from the early Carboniferous in Newfoundland.
Linoproductus is an extinct genus of brachiopod belonging to the order Productida and family Linoproductidae. Specimens have been found in Carboniferous to Permian beds in Asia, North America, and South America.
Diaphragmus is an extinct genus of brachiopod belonging to the order Productida and family Linoproductidae. Specimens have been found in Carboniferous beds in North America.
Marginifera is an extinct genus of brachiopod belonging to the order Productida. Specimens have been found in Carboniferous to Triassic beds in Asia, Europe, Madagascar, and North America.
Pugnoides is an extinct genus of brachiopod belonging to the order Rhynchonellida and family Petasmariidae. Specimens have been found in Devonian to Permian beds in North America, Asia, Europe, western Australia, New Zealand,and New Zealand. The genus was particularly widespread in the Visean.
Linoproductoidea is an extinct superfamily of brachiopods which lived from the Devonian to Permian periods. Their fossils have been found in marine formations dating to those periods on all continents.
Linoproductidae is an extinct family of brachiopods which lived during the Carboniferous and Permian periods. The family was widespread across marine habitats, with fossils having been found on all continents except Antarctica. Members of this family commonly lack dorsal spines, and are characterized in possessing a distinct trail and deep corpus cavity.
Echinoconchinae is an extinct subfamily of brachiopods which lived during the Carboniferous and Permian periods in marine habitats. The family had a cosmopolitan distribution.
Pulchratia is an extinct genus of brachiopods which lived in marine habitats during the Upper Carboniferous period. Its fossils have been found in North America.
