Marginifera is an extinct genus of brachiopod belonging to the order Productida. Specimens have been found in Carboniferous [1] to Triassic [2] beds in Asia, [3] [4] [5] Europe, [6] [7] Madagascar, [8] and North America. [9] [10]
The Permian is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia.
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.
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 2012.
The Gnishik Formation is a geologic formation in Armenia, Azerbaijan and Iran. It preserves fossils dated to the Wordian age of the Permian period.

Productida is an extinct order of brachiopods in the extinct class Strophomenata. Members of Productida first appeared during the Silurian. They represented the most abundant group of brachiopods during the Permian period, accounting for 45-70% of all species. The vast majority of species went extinct during the Permian-Triassic extinction event, though a handful survived into the Early Triassic. Many productids are covered in hollow tubular spines, which are characteristic of the group. A number of functions for the spines have been proposed, including as a defensive mechanism against predators.

Crurithyris is an extinct genus of brachiopod belonging to the order Spiriferida and family Ambocoeliidae.
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.
Rhipidomella is an extinct genus of brachiopod belonging to the order Orthida and family Rhipidomellidae. Specimens have been found in Carboniferous to Permian beds in southwest Asia, the Moscow Basin, and North America.
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.
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.
Eostaffella is an extinct genus of fusulinid belonging to the family Eostaffellidae. Specimens of the genus have been found in Carboniferous to Permian beds in Europe, Asia, and North America.
The Khuff Formation is a geologic formation in Oman and Saudi Arabia. It preserves fossils dating back to the Permian and early Triassic periods.
