Australomedusa is a genus of hydrozoans belonging to the family Australomedusidae. [1]
The species of this genus are found in Southern Australia. [1]
Species: [1]
The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae and the Ochotonidae (pikas). There are 110 recent species of lagomorph of which 109 are extant, including 10 genera of rabbits, 1 genus of hare and 1 genus of pika . The name of the order is derived from the Ancient Greek lagos + morphē.
Tabebuia is a genus of flowering plants in the family Bignoniaceae. Tabebuia consists almost entirely of trees, but a few are often large shrubs. A few species produce timber, but the genus is mostly known for those that are cultivated as flowering trees.
Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found in all tropical and subtropical regions of South America, Africa, Madagascar, Australia-New Guinea, New Zealand, Arabia and the Indian subcontinent. Most species are daytime hunters and live together with ants, mimicking their behavior and sometimes even their chemical traits. Although little is known about most zodariids, members of the genus Zodarion apparently feed only on ants; a number of other genera in the family are apparently also ant specialists.
Ornithomimus is a genus of ornithomimid theropod dinosaurs from the Campanian and Maastrichtian ages of Late Cretaceous Western North America. Ornithomimus was a swift, bipedal dinosaur which fossil evidence indicates was covered in feathers and equipped with a small toothless beak that may indicate an omnivorous diet. It is usually classified into two species: the type species, Ornithomimus velox, and a referred species, Ornithomimus edmontonicus. O. velox was named in 1890 by Othniel Charles Marsh on the basis of a foot and partial hand from the Denver Formation of Colorado. Another seventeen species have been named since then, though almost all of them have been subsequently assigned to new genera or shown to be not directly related to Ornithomimus velox. The best material of species still considered part of the genus has been found in Alberta, representing the species O. edmontonicus, known from several skeletons from the Horseshoe Canyon Formation. Additional species and specimens from other formations are sometimes classified as Ornithomimus, such as Ornithomimus samueli from the earlier Dinosaur Park Formation.
Dromiceiomimus is a genus of ornithomimid theropod from the Late Cretaceous of Alberta, Canada. The type species, D. brevitertius, is considered a synonym of Ornithomimus edmontonicus by some authors, while others consider it a distinct and valid taxon. It was a small ornithomimid that weighed about 135 kilograms (298 lb).
Deinodon is a dubious tyrannosaurid dinosaur genus containing a single species, Deinodon horridus. D. horridus is known only from a set of teeth found in the Late Cretaceous Judith River Formation of Montana and named by paleontologist Joseph Leidy in 1856. These were the first tyrannosaurid remains to be described and had been collected by Ferdinand Vandeveer Hayden. The teeth of Deinodon were slightly heterodont, and the holotype of Aublysodon can probably be assigned to Deinodon.
Chiayusaurus is a genus of sauropod dinosaur known from teeth found in China and possibly also South Korea. Two species have been named for this obscure genus, though only the type, C. lacustris, is still seen as valid. It was originally named as Chiayüsaurus, but the ICZN does not permit special characters, so the name was corrected to Chiayusaurus. The obsolete name can still be seen in older sources, though. As a sauropod, Chiayusaurus would have been a large, quadrupedal herbivore.
Dyslocosaurus is the name given in 1992 to a genus of sauropod dinosaur from the Late Jurassic Period of Wyoming, North America.
Schoepfiaceae is a family of flowering plants recognized in the APG III system of 2009. The family was previously only recognized by few taxonomists; the plants in question usually being assigned to family Olacaceae and Santalaceae.
Acanthochelys is a genus of turtles, the spiny swamp turtles, in the family Chelidae, subfamily Chelinae, found in South America. Until recently, the species of this genus were considered to be members of the genus Platemys, but were moved to the resurrected genus originally described by Gray (1873) based on the type species by monotypy Acanthochelys spixii.
Grandidier's trident bat is a species of bat in the family Hipposideridae endemic to Madagascar. It was formerly assigned to the genus Triaenops, but is now placed in the separate genus Paratriaenops.
Sauroctonus is an extinct genus of gorgonopsian therapsids who lived during the end of the Middle Permian in what is now European Russia. The first fossils, discovered in Tatarstan, were first considered to belong to a new species of the South African genus Arctognathus, named A. progressus in 1938. The taxon will be designated as such until 1940, when it will be assigned to the genus Inostrancevia by Ivan Yefremov, before being definitively classified in a separate genus erected by Alexey Bystrow in 1955. The most complete known fossils of S. progressus include cranial and postcranial elements currently all recorded in Tatarstan. These elements show that the animal is a rather medium-sized gorgonopsian.
Ruthenosaurus is an extinct genus of caseid synapsids that lived in what is now southern France during the Early Permian about 285 million years ago. It is known from the holotype MNHN.F.MCL-1 an articulated partial postcranial skeleton. It was collected by D. Sigogneau-Russell and D. Russell in 1970 in the upper part of the M2 Member, Grès Rouge Group, in the Rodez Basin, near the village of Valady, in Occitanie Region. It was first named by Robert R. Reisz, Hillary C. Maddin, Jörg Fröbisch and Jocelyn Falconnet in 2011, and the type species is Ruthenosaurus russellorum.
Euromycter is an extinct genus of caseid synapsids that lived in what is now southern France during the Early Permian about 285 million years ago. The holotype and only known specimen of Euromycter (MNHN.F.MCL-2) includes the complete skull with lower jaws and hyoid apparatus, six cervical vertebrae with proatlas, anterior part of interclavicle, partial right clavicle, right posterior coracoid, distal head of right humerus, left and right radius, left and right ulna, and complete left manus. It was collected by D. Sigogneau-Russell and D. Russell in 1970 at the top of the M1 Member, Grès Rouge Group, near the village of Valady, Rodez Basin. It was first assigned to the species "Casea" rutena by Sigogneau-Russell and Russell in 1974. More recently, it was reassigned to its own genus, Euromycter, by Robert R. Reisz, Hillary C. Maddin, Jörg Fröbisch and Jocelyn Falconnet in 2011. The preserved part of the skeleton suggests a size between 1,70 m (5,5 ft) and 1,80 m (5,9 ft) in length for this individual.
This timeline of ornithomimosaur research is a chronological listing of events in the history of paleontology focused on the ornithomimosaurs, a group of bird-like theropods popularly known as the ostrich dinosaurs. Although fragmentary, probable, ornithomimosaur fossils had been described as far back as the 1860s, the first ornithomimosaur to be recognized as belonging to a new family distinct from other theropods was Ornithomimus velox, described by Othniel Charles Marsh in 1890. Thus the ornithomimid ornithomimosaurs were one of the first major Mesozoic theropod groups to be recognized in the fossil record. The description of a second ornithomimosaur genus did not happen until nearly 30 years later, when Henry Fairfield Osborn described Struthiomimus in 1917. Later in the 20th century, significant ornithomimosaur discoveries began occurring in Asia. The first was a bonebed of "Ornithomimus" asiaticus found at Iren Debasu. More Asian discoveries took place even later in the 20th century, including the disembodied arms of Deinocheirus mirificus and the new genus Gallimimus bullatus. The formal naming of the Ornithomimosauria itself was performed by Rinchen Barsbold in 1976.
Dentex is a genus of fish in the family Sparidae.
Daboia is a genus of venomous vipers.
Thereuodon is a genus of extinct mammal known from the Early Cretaceous of southern England, Morocco and France. The type species, named by Denise Sigogneau-Russell in 1989 for teeth from the earliest Cretaceous Ksar Metlili Formation of Morocco, is Thereuodon dahmani, while the referred species named by Sigogneau-Russell and Paul Ensom for teeth from the Lulworth Formation of England is Thereuodon taraktes. The two species are separated by a break in the cingulum in T. dahmani, a more obtuse medial crest in T. taraktes, a duller stylocone in T. taraktes, a "c" cuspule in T. dahmani, and a reduced facet A in T. taraktes. The genus Thereuodon is the only taxon in the symmetrodont family Thereuodontidae, which may be closely related to Spalacotheriidae. A tooth referred to T. cf. taraktes is known from the Berriasian aged Angeac-Charente bonebed of France.
Stylidens is an extinct genus of mammaliaforms, possibly belonging to Morganucodonta, that lived in what is now England during the Middle Jurassic. Its type species is Stylidens hookeri, which was named in 2016 by Percy M. Butler and Denise Sigogneau-Russell from an isolated lower molar found at the Forest Marble Formation. A second molar referable to the genus is also known, which may represent a separate species.
