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]
Craspedodon is an extinct genus of ornithischian dinosaur, possibly a ceratopsian. It lived during the Late Cretaceous, in what is now Belgium. Only a few teeth have ever been found, which were described as similar to those of Iguanodon. Craspedodon lonzeensis, described by Louis Dollo in 1883, is the type species, although it is considered a nomen dubium since it is based on fragmentary material. It was long thought to be an iguanodontian, but a 2007 restudy suggested that it was actually a neoceratopsian, perhaps closer to Ceratopsoidea than Protoceratopsidae. If the reidentification is correct, Craspedodon would be the first neoceratopsian known from Europe.
The family Notopteridae contains 10 species of osteoglossiform (bony-tongued) fishes, commonly known as featherbacks and knifefishes. These fishes live in freshwater or brackish environments in Africa and South and Southeast Asia.
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.
Goniosaurus is an extinct genus of plesiosaur from the Late Cretaceous of the Nekum Chalk, in Netherlands. The only species so far described, G. binskhorsti is represented only by an isolated, compressed and slender tooth described by Hermman Meyer and a referred tooth and a cervical vertebra that shows that was an elasmosaurid, as many others Late Cretaceous plesiosaurs from Europe.
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, China Asia 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.
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.
Argyrotheca is a genus of very small to minute lampshells. All species share a large pedicel opening, one ridge on the inside of the pedunculate valve, pits in a diamond pattern on the inside of both valves, and without radial ridges that end in tubercles. It occurs in depths between 6 and 1300 m. It is known since the latest Cretaceous.
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).
Mycteriacetus is an extinct genus of dolphin from the Early Miocene (Burdigalian) of northeastern Italy. The type species is M. bellunensis.
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.
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.
