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.
Terebratula species have biconvex egg-shaped shells, anterior margins of the valves have two small folds, concentric growth lines are quite thin or nearly absent. The larger valve has a ventral umbo with the opening through which they extend a short peduncle. [1]
As Terebratula has been erected early on in paleontology, many species have since been reassigned to other genera. [2]
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.
Kingena is an extinct genus of primarily Cretaceous-aged brachiopods of the family Kingenidae whose fossils are found in marine strata of Antarctica, Europe, and New Zealand. Early Paleocene-aged fossils from Denmark represent the youngest species.
Baleiichthys is a genus of extinct freshwater ray-finned fish, belonging to the teleosts. It lived in the Middle Jurassic, and its fossil remains have been found in northern Asia. Almost nothing is known about it.
Aphnelepis is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Late Jurassic epoch. It contains a single species, A. australis, from the Talbragar River beds of New South Wales, Australia.
Congosaurus is an extinct genus of dyrosaurid mesoeucrocodylian. Fossils have been found from Lândana, in Angola and date back to the Paleocene epoch. In 1952 and 1964 Congosaurus was proposed to be synonymous with Dyrosaurus. The genus was later thought synonymous with Hyposaurus in 1976 and 1980. It has since been proven a distinct genus of dyrosaurid separate from both Dyrosaurus and Hyposaurus.
The Bayan Mandahu Formation is a geological unit of "redbeds" located near the village of Bayan Mandahu in Inner Mongolia and China and dates from the late Cretaceous Period. Laid down in the Campanian, it is dated somewhat uncertainly to between 75 and 71 mya.
Opsithrissops is an extinct genus of prehistoric bony fish that lived during the Thanetian stage of the Paleocene epoch. It is a 120 centimetres (3.9 ft) fish in the family Osteoglossiformes which includes other bony-tongues such as the extant species of arowana and arapaima.
Ceramurus is an extinct genus of prehistoric marine ray-finned fish from the Late Jurassic. It contains a single species, C. macrocephalus from the Purbeck Group of England.
Anomia is a genus of saltwater clams, marine bivalve mollusks in the family Anomiidae. They are commonly known as jingle shells because when a handful of them are shaken they make a jingling sound, though some are also known as saddle oysters.
Camarotoechia is an extinct genus of brachiopods found in Paleozoic strata.
Crania is an extinct genus of brachiopods that lived during the Upper Cretaceous.
Hensodon spinosus is an extinct pycnodontid that lived during the Upper Cenomanian of what is now Lebanon. H. spinosus superficially resembled a marine angelfish with a massive head, and a very spiny pectoral girdle. Different specimens have different arrangements of the horn-like frontal spines. One form has the horns arranged as a double-prong, assumed to be the male, and the other form, assumed to be the female, having the horns one after the other, like those of a rhinoceros.
Physeterula was a prehistoric close relative of the sperm whale from the Miocene. Its fossils have been found in Europe and the United States.
Isocrania is an extinct genus of brachiopods found during the Upper Cretaceous. Early representatives were attached to the underground, but later species are presumed to be free living at an increasingly earlier age. This was probably an adaptation to the increasing very thick and fine sedimentation during the latest Cretaceous.
Eudelphis is an extinct genus of sperm whale belonging to Physeteroidea that lived in the ancient North Sea basin about 16-11 million years ago, during the middle Miocene (Langhian).
Lusitanops gigasei is an extinct species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Its specific name derives from the paleontologist Paul Gigase, the collector of the fossil specimen designated as the holotype.
The Sainte-Barbe Clays Formation is a geological formation in Belgium. It is found in localised areas of the northern margin of the Mons Basin, alongside the equivalently aged Hautrage and Baudour Clay Formations. It is Upper Barremian-Lower Aptian in age. It predominantly consists of laminated clay, with some lignite. It is well known for the "Iguanodon sinkhole" locality near Bernissart where many specimens of Iguanodon bernissartensis were described by Louis Dollo in the late 19th century.
The European Journal of Taxonomy is a peer-reviewed open access scientific journal for descriptive taxonomy of living and fossil eukaryotes, covering subjects in zoology, botany, and palaeontology. It is supported by the EJT Consortium, a group of European natural history institutes, which fully funds the publication. Therefore, the journal is free for both authors and readers.
Alvania craticula is an extinct species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.
