Dinosaur genera

Qantassaurus ( ) is a genus of basal two-legged, plant-eating elasmarian ornithischian dinosaur that lived in Australia about 125-112 million years ago, when the continent was still partly south of the Antarctic Circle. It was described by Patricia Vickers-Rich and her husband Tom Rich in 1999 after a find near Inverloch, and named after Qantas, the Australian airline.

Anabisetia ( ) is a genus of ornithopod dinosaur from the Late Cretaceous Period of Patagonia, South America. It was a small bipedal herbivore, around long.

Malawisaurus (meaning "Malawi lizard") is an extinct genus of titanosaurian sauropod dinosaur. It is known from the Dinosaur Beds of northern Malawi, which probably date to the Aptian stage of the Early Cretaceous. The type species is M. dixeyi and the specific name honours Frederick Augustus Dixey.

Sinocalliopteryx (meaning 'Chinese beautiful feather') is a genus of carnivorous coelurosaurian theropod dinosaurs from the Lower Cretaceous Yixian Formation of China (Jianshangou Beds, dating to 124.6 Ma). While similar to the related Huaxiagnathus, Sinocalliopteryx were larger. In 2007, the type specimen was the largest known compsognathid exemplar, at in length. In 2012, an even larger specimen was reported.

Pelorosaurus ( ; meaning "monstrous lizard") is a genus of titanosauriform sauropod dinosaur. Remains referred to Pelorosaurus date from the Early Cretaceous period, about 140–125 million years ago, and have been found in England. Thomas Holtz estimated its length at . The name Pelorosaurus was one of the first to be given to any sauropod. Many species have been assigned to the genus historically, but most are currently considered to belong to other genera. Problematically, the first named species of Pelorosaurus, P. conybeari, is a junior synonym of Cetiosaurus brevis (now Pelorosaurus brevis

Dinheirosaurus is a genus of diplodocid sauropod dinosaur that is known from fossils uncovered in modern-day Portugal. It may represent a species of Supersaurus. The only species is Dinheirosaurus lourinhanensis, first described by José Bonaparte and Octávio Mateus in 1999 for vertebrae and some other material from the Lourinhã Formation. Although the precise age of the formation is not known, it can be dated around the early Tithonian of the Late Jurassic.

Chialingosaurus (meaning "Chialing Lizard") is a genus of herbivorous stegosaurian dinosaur similar to Kentrosaurus from the Upper Shaximiao Formation, Late Jurassic beds in Sichuan Province in China. Its age makes it one of the oldest species of stegosaurs, living about 160 million years ago. Since it was an herbivore, scientists think that Chialingosaurus probably ate ferns and cycads, which were plentiful during the period when Chialingosaurus was alive.

Nipponosaurus (meaning "Japanese lizard") is a lambeosaurine hadrosaur from sediments of the Yezo Group, in Sinegorsk on the island of Sakhalin, which was part of Japan at the time of the species' classification. The type and only species is N. sachalinensis, known only from a single juvenile specimen discovered in 1934 and named in 1936, by Takumi Nagao, with further material of the same individual found in 1937. Since then, the taxon has been largely ignored, and its validity has been doubted, with synonymy with other Asian hadrosaurs or status as a nomen dubium being suggested. Redescriptio

Elmisaurus (meaning "foot sole lizard") is an extinct genus of caenagnathid theropod dinosaur from the Late Cretaceous Nemegt Formation of Mongolia.

Erlikosaurus (meaning "Erlik's lizard") is a genus of therizinosaurid that lived in Asia during the Late Cretaceous period. The fossils, a skull and some post-cranial fragments, were found in the Bayan Shireh Formation of Mongolia in 1972, dating to around 96 and 89 million years ago. These remains were later described by Altangerel Perle and Rinchen Barsbold in 1980, naming the new genus and species Erlikosaurus andrewsi. It represents the second therizinosaur taxon from this formation (after Segnosaurus), with the most complete skull among members of this peculiar family of dinosaurs.

Huaxiagnathus is an extinct genus of coelurosaurian theropod dinosaur from the Lower Cretaceous of China. The genus contains a single species, Huaxiagnathus orientalis, known from two immature individuals from the Yixian Formation. Huaxiagnathus may represent an earlier ontogenetic stage of the tyrannosauroid Sinotyrannus from the younger Jiufotang Formation.

Indosaurus () is a genus of carnivorous theropod dinosaur that lived in what is now India, about 69 to 66 million years ago during the Maastrichtian division of the Late Cretaceous.

Ozraptor (meaning "Australian thief") is a genus of possibly abelisauroid theropod dinosaur from the Middle Jurassic (Bajocian) Colalura Sandstone of Australia, known from fragmentary remains.

Dubreuillosaurus is a genus of carnivorous megalosaurid theropod dinosaur from the middle Jurassic Period. Its fossils were found in France. The only named species, Dubreuillosaurus valesdunensis, was originally described as a species of Poekilopleuron, Poekilopleuron? valesdunensis, which is still formally the type species of the genus. It was later renamed Dubreuillosaurus valesdunensis when, in 2005, Allain came to the conclusion that it was not part of the genus Poekilopleuron. Its type specimen, MNHN 1998-13, is only rivalled in the number of preserved elements in this group by that of Eu

Anchiornis is a genus of small, four-winged paravian dinosaurs, with only one known species, the type species Anchiornis huxleyi, named for its similarity to modern birds. The Latin name Anchiornis derives from a Greek word meaning "near bird", and huxleyi refers to Thomas Henry Huxley, a contemporary of Charles Darwin. Anchiornis fossils have been found only in the Tiaojishan Formation of Liaoning, China, in rocks dated to the Late Jurassic, about 160 million years ago. It is known from hundreds of specimens, and given the exquisite preservation of some of these fossils, it became the first M

Itemirus is a genus of dromaeosaurid theropod dinosaur from the Turonian aged Bissekty Formation of the Late Cretaceous period of Uzbekistan.

Aristosuchus (from the Ancient Greek ἄριστος, meaning "bravest, best, noblest", and σουχος, the Ancient Greek corruption of the name of the Egyptian crocodile-headed god Sobek) is a genus of small coelurosaurian dinosaur that lived in the Early Cretaceous period (Barremian stage, sometime between 130 and 123 million years ago) of what is now England, UK. The type and only species is Aristosuchus pusillus, originally referred to the carnosaurian genus Poekilopleuron.

Fabrosaurus ( ) is a dubious extinct genus of ornithischian dinosaur that lived during the Early Jurassic during the Hettangian to Sinemurian stages (199 - 189 mya).

The key rebbachisaurid features are the spinopostzygapophyseal laminae that extends dorsomedially from the postzygapophyses to join and form the postspinal lamina, and the pneumatic neural spine and arch. Other rebbachisaurid features include the rather simple ("attenuated") structure of the neural spine and the respective inclinations of the centrodiapophyseal lamina and the postzygodiapophyseal l

Pegomastax is a genus of heterodontosaurid dinosaur that lived during the Early Jurassic of South Africa. The only known specimen was discovered in a 1966–1967 expedition in Transkei District of Cape Province, but was not described until 2012 when Paul Sereno named it as the new taxon Pegomastax africana. The genus name is derived from the Greek for "strong jaw", and the species name describes the provenance of Africa; it was originally spelled africanus, was corrected to africana to align with the gender of the genus name.

Koreaceratops () is a genus of basal ceratopsian dinosaur discovered in Albian-aged (Early Cretaceous) rocks of South Korea.

Ceratops (meaning ) is a dubious genus of herbivorous ceratopsian dinosaur which lived during the Late Cretaceous. Its fossils have been found in the Judith River Formation in Montana. Although poorly known, Ceratops is important in the history of dinosaurs, since it is the type genus for which both the Ceratopsia and the Ceratopsidae have been named.

Glacialisaurus is a genus of sauropodomorph dinosaur from the Early Jurassic period of Antarctica. It is known from two specimens; the holotype (name-bearing specimen), a partial tarsus (ankle) and metatarsus, and a partial left femur (thigh bone). The fossils were collected by a team led by paleontologist William R. Hammer during a 1990–91 field expedition to the central region of the Transantarctic Mountains. They come from sedimentary rocks of the Hanson Formation and date to the Pliensbachian stage of the Early Jurassic, around 186 to 182 million years ago. The fossils were described in 20

Chilesaurus is an extinct genus of herbivorous dinosaur. While its exact classification is uncertain, many researchers believe it is a theropod, with a minority of academics suggesting that it may be an ornithischian. The type and only known species so far is Chilesaurus diegosuarezi. Chilesaurus lived between 148-147 million years ago (Mya) in the Late Jurassic period of Chile. Showing a combination of traits from theropods, ornithischians, and sauropodomorphs, this genus has far-reaching implications for the evolution of dinosaurs, such as whether the traditional saurischian-ornithischian sp

Animantarx ( ; meaning 'living citadel') is a genus of nodosaurid ankylosaurian dinosaur from the Early and Late Cretaceous of western North America. Like other nodosaurs, it would have been a slow-moving quadrupedal herbivore covered in heavy armor scutes, but without a tail club. The skull measures approximately 25 cm (10 inches) in length, suggesting the animal as a whole was no more than 3 meters (10 feet) long.

Sinotyrannus (meaning "Chinese tyrant") is an extinct genus of large tyrannosauroid theropod dinosaurs known from the Early Cretaceous Jiufotang Formation of Liaoning, China. This genus contains a single species, Sinotyrannus kazuoensis, known from a single mature specimen including a partial skull, some vertebrae, and part of the pelvic girdle.

Limusaurus is a genus of theropod dinosaur that lived in what is now China during the Late Jurassic, around 161 to 157 million years ago. The type and only species Limusaurus inextricabilis was described in 2009 from specimens found in the Upper Shishugou Formation in the Junggar Basin of China. The genus name consists of the Latin words for "mud" and "lizard", and the species name means "impossible to extricate", both referring to these specimens possibly dying after being mired. Limusaurus was a small, slender animal, about in length and in weight, which had a long neck and legs bu

Minotaurasaurus (meaning "Minos'-bull reptile") is a monospecific genus of ankylosaurid dinosaur that lived in Mongolia during the Late Cretaceous (late Campanian stage, ~75-71 Ma) in what is now the Djadochta Formation. The type and only species, Minotaurasaurus ramachandrani, is known from two skulls, a cervical vertebra and a cervical half ring. It was named and described in 2009 by Clifford Miles and Clark Miles. The holotype of Minotaurasaurus has been suspected to be illegally exported out of Mongolia. It has been suggested to be a synonym of Tarchia but more recent publications consider

Coahuilaceratops (meaning "horned face from Coahuila") is a genus of chasmosaurine ceratopsian dinosaur that lived during the early Maastrichtian age of the Late Cretaceous epoch, about 71.5 to 70.5 million years ago in what is now northern Mexico.

Panphagia is a genus of sauropodomorph dinosaur described in 2009. It lived around 231 million years ago, during the Carnian age of the Late Triassic period in what is now northwestern Argentina. Fossils of the genus were found in the La Peña Member of the Ischigualasto Formation in the Ischigualasto-Villa Unión Basin. The name Panphagia comes from the Greek words ', meaning "all", and ', meaning "to eat", in reference to its inferred omnivorous diet. Panphagia is one of the earliest known dinosaurs, and is an important find which may mark the transition of diet in early sauropodomorph di

Hesperonychus (meaning "western claw") is a genus of small dromaeosaurid dinosaur. There is one described species, Hesperonychus elizabethae. The type species was named in honor of Dr. Elizabeth Nicholls of the Royal Tyrrell Museum of Palaeontology who collected it as a student in 1982. It is known from fossils recovered from the Dinosaur Park Formation and possibly from the uppermost strata of the Oldman Formation of Alberta, dating to the Campanian stage of the Late Cretaceous around .

Tianyuraptor is a genus of short-armed dromaeosaurid dinosaur ('running lizard'; a type of small dinosaur considered to be closely related to birds) that lived during the Early Cretaceous, about 122 million years ago. Its remains have been found in western Liaoning, China. It was similar to other dromaeosaurids found in Liaoning, with the exception of being somewhat more primitive. The type specimen, formally named in 2009, shows features not seen in previously known Northern Hemisphere (Laurasian) dromaeosaurids, but present in Southern Hemisphere (Gondwanan) species and early birds. Because

Zizhongosaurus (meaning "Zizhong lizard") is a genus of basal herbivorous sauropod dinosaur which lived in the Early Jurassic (Toarcian) Period of China. It was a large-bodied herbivore characterized by a long neck.

Eucnemesaurus (; meaning "good tibia lizard", for its robust tibiae) is a basal sauropodomorph dinosaur genus usually considered to be a synonym of Euskelosaurus. Recent study by Yates (2006), however, indicates that it is valid and the same animal as putative "giant herrerasaurid" Aliwalia.

Aviatyrannis is a genus of coelurosaurian theropod dinosaur, either a tyrannosauroid or an ornithomimosaurian, from the Oxfordian-Tithonian stages of the Late Jurassic found in Portugal.

Velafrons (meaning "sailed forehead") is a genus of lambeosaurine hadrosaurid dinosaur from the Late Cretaceous of Mexico. It is known from a mostly complete skull and partial skeleton of a juvenile individual, with a bony crest on the forehead. Its fossils were found in the late Campanian-aged Cerro del Pueblo Formation (about 73.5 million years ago), near Rincon Colorado, Coahuila. The type specimen is CPC-59, and the type species is V. coahuilensis.

Mantellisaurus is a genus of iguanodontian dinosaur that lived in the Barremian and early Aptian ages of the Early Cretaceous Period of Europe. Its remains are known from Belgium (Bernissart), England, Spain and Germany. The type and only species is M. atherfieldensis. Formerly known as Iguanodon atherfieldensis, the new genus Mantellisaurus was erected for the species by Gregory Paul in 2007. According to Paul, Mantellisaurus was more lightly built than Iguanodon and more closely related to Ouranosaurus, making Iguanodon in its traditional sense paraphyletic. It is known from many complete an

Xenotarsosaurus is a genus of abelisaurid theropod dinosaur that lived during the Late Cretaceous of Argentina.

Cerasinops (meaning 'cherry face') was a small ceratopsian dinosaur. It lived during the Campanian of the late Cretaceous Period. Its fossils have been found in Two Medicine Formation, in Montana. The type species of the genus Cerasinops is C. hodgskissi.

It lived during the Cenomanian to Turonian of the Cretaceous period, between 96-91 million years ago. The type species, Aniksosaurus darwini, was formally described from the Bajo Barreal Formation of the Golfo San Jorge Basin by Rubén Dario Martínez and Fernando Emilio Novas in 2006; the name was first coined in 1995 and reported in the l

Lusotitan is a genus of herbivorous brachiosaurid sauropod dinosaur from the Late Jurassic of Portugal.

Liaoceratops, meaning "Liaoning horned face", is a ceratopsian dinosaur believed to be an early relative of the horned ceratopsids. It lived in the Early Cretaceous, 126 million years ago. It was discovered in China by a team of American and Chinese scientists. Liaoceratops was much smaller than its later relatives, but offers a glimpse into the early evolution of this group of dinosaurs. ==Discoveries and naming== left|thumb|Skeletal restoration Liaoceratops was discovered in the famous Liaoning Province of China, where several fossils of feathered dinosaurs have also been collected. The type

Jaxartosaurus (meaning "Jaxartes lizard" after the early name of the Syr Darya) is a genus of hadrosaurid dinosaur similar to Corythosaurus which lived during the Late Cretaceous. Its fossils were found in Kazakhstan.

Heyuannia ("from Heyuan") is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous epoch, in what is now China and Mongolia. It was the first oviraptorid found in China; most others were found in neighbouring Mongolia. Two species are known: H. huangi, named by Lü Junchang in 2002 from the Dalangshan Formation; and H. yanshini, originally named as a separate genus Ingenia from the Barun Goyot Formation by Rinchen Barsbold in 1981, and later renamed to Ajancingenia in 2013 due to the preoccupation of Ingenia. The latter name was eventually discarded due to various ethica

Eodromaeus (meaning "dawn runner") is an extinct genus of probable basal theropod dinosaurs from the Late Triassic of Argentina. Like many other of the earliest-known dinosaurs, it hails from the Carnian-age (~230 Ma) Ischigualasto Formation, within the Ischigualasto-Villa Unión Basin of northwestern Argentina. Upon its discovery, it was argued to be one of the oldest true theropods, supplanting its contemporary Eoraptor, which was reinterpreted as a basal sauropodomorph.
