Dinosaur genera

Khankhuuluu ( ; ) is an extinct genus of early tyrannosauroid theropod dinosaurs from the Late Cretaceous of what is now the Gobi Desert in Mongolia. The genus contains a single species, Khankhuuluu mongoliensis, known from several skull bones and two partial skeletons, including shoulder, pelvic, and hindlimb bones, and several vertebrae from the back and tail. The remains were discovered in 1972 and 1973 and first described in 1977 as belonging to the Chinese Alectrosaurus. Later researchers recognized the uniqueness of the bones, and they were eventually named as belonging to a new species

Unescoceratops is a genus of leptoceratopsid ceratopsian dinosaurs known from the Late Cretaceous of Alberta, southern Canada. It contains a single species, Unescoceratops koppelhusae.

Agrosaurus (; perhaps from Greek agros meaning 'field' and sauros meaning 'lizard', "field lizard") is a potentially dubious genus of thecodontosaurid sauropodomorph probably originating from the Magnesian Conglomerate of England that was originally believed to be a Triassic prosauropod from Australia. Agrosaurus would thus be the oldest dinosaur from that country. However, this appears to have been an error, and the material actually appears to come from Thecodontosaurus or a Thecodontosaurus-like animal from Bristol, England (Avon Fissure Fill). The type species is Agrosaurus macgillivrayi.

Berthasaura (meaning "Bertha's lizard") is an extinct genus of ceratosaurian theropod dinosaurs from the Early Cretaceous Goio-Erê Formation of Paraná, Brazil. The genus contains a single species, Berthasaura leopoldinae, known from a nearly complete skeleton.

Rayososaurus is an extinct genus of sauropod dinosaur in the family Rebbachisauridae. Rayososaurus was named by Argentinian paleontologist José Bonaparte in 1996. Its type and only accepted species is Rayososaurus agrioensis. The species Limaysaurus tessonei was at one point included in Rayososaurus as Rayososaurus tessonei.

Spicomellus is an extinct genus of unusual early ankylosaurian dinosaur from the El Mers III Formation (Bathonian age) of Morocco. The genus contains a single species, Spicomellus afer, representing the oldest named definitive ankylosaur. The species was initially described in 2021 based on a single rib with fused osteoderms, rendering its life appearance and relationships uncertain. In 2025, several additional bones, including osteoderms and cranial and postcranial remains, were described, revealing that it bears a unique array of spines over the body, including extremely elongated spikes aro

Trachodon (meaning "rough tooth") is a dubious genus of hadrosaurid dinosaur based on teeth from the Campanian-aged (Upper Cretaceous) Judith River Formation of Montana, U.S. It is a historically important genus with a convoluted taxonomy that has been all but abandoned by modern dinosaur paleontologists. Despite being used for decades as the iconic hadrosaurid dinosaur, the material it is based on is composed of teeth from both hadrosaurids and ceratopsids (their teeth have a distinctive double root), and its describer, Joseph Leidy, came to recognize the difference and suggested limiting the

Saltriovenator (meaning "Saltrio hunter") is a genus of ceratosaurian dinosaur that lived during the Sinemurian stage of the Early Jurassic in what is now Italy. The type and only species is Saltriovenator zanellai; in the past, the species had been known under the informal name "saltriosaur". Although a full skeleton has not yet been discovered, Saltriovenator is thought to have been a large, bipedal carnivore similar to Ceratosaurus.

Hypselospinus is a genus of iguanodontian dinosaur which was first described as a species of Iguanodon (I. fittoni) by Richard Lydekker in 1889, the specific name honouring William Henry Fitton.

Jaklapallisaurus is a genus of unaysaurid sauropodomorph dinosaur. It lived during the Late Triassic period (late Norian to earliest Rhaetian) in what is now Telangana, central India. The genus is monotypic, only including the species Jaklapallisaurus asymmetricus.

Atsinganosaurus is a genus of titanosaurian sauropod dinosaur which existed in what is now France during the Late Cretaceous. Well-preserved remains (and the only known) of Atsinganosaurus were collected from the Grès à Reptiles Formation of the Aix-en-Provence Basin. The type and only species is A. velauciensis.

Ulughbegsaurus (meaning "Ulugh Beg's lizard") is an extinct genus of carcharodontosaurid theropod dinosaurs from the Late Cretaceous Bissekty Formation (Turonian age) and Khodzhakul Formation (Cenomanian age) of Uzbekistan. The genus contains a single species, Ulughbegsaurus uzbekistanensis, known from multiple maxilla fragments.

Tanius (meaning "of Tan") is a genus of hadrosauroid dinosaur. It lived in the Late Cretaceous of China. The type species, named and described in 1929 by Carl Wiman, is Tanius sinensis. The generic name honours the Chinese paleontologist Tan Xichou ("H.C. Tan"). The specific epithet refers to China. In 2010 Gregory S. Paul estimated the length of Tanius at and its weight at .

Yurgovuchia (meaning "coyote") is a genus of dromaeosaurid theropod dinosaurs that lived in North America during the Early Cretaceous period in what is now the Cedar Mountain Formation. It contains a single species, Yurgovuchia doellingi. The remains were discovered in Utah, United States.

Ohmdenosaurus () is a genus of sauropod dinosaur that lived during the Early Jurassic epoch in what is now Germany. The only specimen – a tibia (shinbone) and ankle – was discovered in rocks of the Posidonia Shale near the village of Ohmden. The specimen, which was originally identified as a plesiosaur, is exhibited in a local museum, the Urweltmuseum Hauff. In the 1970s, it caught the attention of German palaeontologist Rupert Wild, who recognised it as the remains of a sauropod. Wild named Ohmdenosaurus in a 1978 publication; the only known species is Ohmdenosaurus liasicus.

Pycnonemosaurus (meaning 'dense forest lizard') is a genus of carnivorous theropod dinosaur that belonged to the family Abelisauridae. It was found in the Upper Cretaceous red conglomerate sandstones of the Cachoeira do Bom Jardim Formation, Mato Grosso, Brazil, and it lived during the late Campanian to early Maastrichtian stage of the Late Cretaceous.

Dahalokely is an extinct genus of carnivorous abelisauroid theropod dinosaur from the Late Cretaceous (Turonian) of Madagascar.

Zhejiangosaurus (meaning "Zhejiang lizard") is an extinct genus of ankylosaurian dinosaur from the Upper Cretaceous (Cenomanian stage) of Zhejiang, eastern China. It was first named by a group of Chinese authors Lü Junchang, Jin Xingsheng, Sheng Yiming and Li Yihong in 2007 and the type species is Zhejiangosaurus lishuiensis ("from Lishui", where the fossil was found). It has no diagnostic features, and thus is a nomen dubium.

Similicaudipteryx, meaning "similar to Caudipteryx" (which itself means "tail feather"), is a genus of theropod dinosaur of the family Caudipteridae.

Latenivenatrix, meaning "hiding huntress", is a genus of large troodontid known from a single species, L. mcmasterae. Along with the contemporary Stenonychosaurus, it is known from non-tooth fossils that were formerly assigned to the now potentially dubious genus Troodon. Although described as separate, it has been considered a junior synonym of Stenonychosaurus.

Gyposaurus (meaning "vulture lizard", referring to the outdated hypothesis that prosauropods were carnivores) is a genus of basal sauropodomorph dinosaur from the early Jurassic of South Africa. It is usually considered to represent juveniles of other prosauropods, but "G." sinensis is regarded as a possibly valid species.

Gravitholus (meaning 'heavy dome') was a genus of pachycephalosaurid dinosaur from the late Cretaceous period (Campanian stage, around 75 million years ago). It was a pachycephalosaur, and like other pachycephalosaurids the skull roof formed a thick dome made of dense bone, which may have been used in head-butting contests over mates or territory. It lived in what is now Alberta, Canada, and was described in 1979 by W. P. Wall and Peter Galton. The type species is Gravitholus albertae.

Monkonosaurus (meaning "Monkon lizard") is a dubious genus of herbivorous stegosaurian dinosaur from the Late Jurassic/Early Cretaceous-aged Loe-ein Formation of Tibet (or the Early Cretaceous Lura Formation of China). Some sources place it as alive during the Oxfordian - Albian stages, around 163 - 100 million years ago, although Monkonosaurus was probably only alive during the Late Jurassic (163 – 152.1 ± 0.9 million years ago), making it among the earliest known stegosaurs along with Chungkingosaurus and Bashanosaurus.

Erliansaurus (meaning "Erlian lizard") is a genus of therizinosaurian theropod dinosaur that lived in Asia during the Cenomanian stage of the Late Cretaceous period in what is now Nei Mongol, Iren Dabasu Formation.

Ahshislepelta (meaning "Ah-shi-sle-pah Wash shield") is a monospecific genus of ankylosaur dinosaur from New Mexico that lived during the Late Cretaceous (late Campanian stage, 74.5 Ma) in what is now the Hunter Wash Member of the Kirtland Formation. The type and only species, Ahshislepelta minor, is known only from an incomplete postcranial skeleton of a small subadult or adult individual. It was named in 2011 by Michael Burns and Robert M. Sullivan. Based on the size of the humerus, Ahshislepelta is larger than Pinacosaurus mephistocephalus but smaller than Talarurus and Pinacosaurus granger

Sonorasaurus is a genus of brachiosaurid sauropod dinosaur from the Early to Late Cretaceous (Albian to Cenomanian stages, around 112 to 93 million years ago). Its fossils have been found in southern Arizona, United States. Its name, which means "Sonora lizard", comes from the Sonora River that flows in the Sonoran Desert where its fossils were first found. The type species is S. thompsoni, described by Ratkevich in 1998.

Hoplitosaurus (meaning "Hoplite lizard") was a genus of armored dinosaur related to Polacanthus. It was named from a partial skeleton found in the Barremian (Early Cretaceous) Lakota Formation of Custer County, South Dakota. It is an obscure genus which has been subject to some misinterpretation of its damaged remains. Although there was a push to synonymize it with Polacanthus in the late 1980s-early 1990s, Hoplitosaurus has been accepted as a valid albeit poorly known genus in more recent reviews.

Regnosaurus (meaning "Sussex lizard") is an extinct genus of herbivorous presumably armored dinosaur known from the early Cretaceous Wealden Formation of England. The genus contains a single species, Regnosaurus northamptoni, known from a single partial jaw bone. Regnosaurus has traditionally been regarded as a stegosaur, possibly related to the Jurassic Huayangosaurus of China. Later research considers it to be a dubious, indeterminate thyreophoran.

Pantydraco (where "panty-" is short for Pant-y-ffynnon, signifying hollow of the spring/well in Welsh, referring to the quarry at Bonvilston in South Wales where it was found) is a genus of basal sauropodomorph dinosaur from the Late Triassic of the United Kingdom (Wales). It is based on a partial juvenile skeleton once thought to belong to Thecodontosaurus. Only one valid species of Pantydraco is recognised: P. caducus.

Jiangjunosaurus is an extinct genus of herbivorous stegosaurian dinosaurs from the Oxfordian-age (Upper Jurassic) Shishugou Formation of the Junggar Basin, Xinjiang, China.

Suuwassea is a genus of dicraeosaurid sauropod dinosaur found in Upper Jurassic strata of the Morrison Formation, located in southern Carbon County, Montana, United States. The fossil remains were recovered in a series of expeditions during a period spanning the years 1999 and 2000 and were described by J.D. Harris and Peter Dodson in 2004. They consist of a disarticulated but associated partial skeleton, including partial vertebral series and limb bones.

Penelopognathus (meaning "wild duck jaw") is a genus of hadrosauroid dinosaur which lived in the Early Cretaceous Bayin-Gobi Formation in what is now China. The discovery of this taxon contributes to the hypothesis that hadrosauroids originated in Asia. The type species, Penelopognathus weishampeli, named after David Weishampel, was described by Godefroit, Li, and Shang in 2005, based on fragmentary jaw fossils.

Urbacodon (meaning "URBAC tooth") is a genus of troodontid theropod dinosaur. Two species have been described, both of which are known from a partial dentary: U. itemirensis from the Dzharakuduk Formation (Cenomanian) of Uzbekistan and U. norelli from the Iren Dabasu Formation of China. Possible remains are also known from the Bissekty Formation (Turonian) of Uzbekistan.

Nedcolbertia is a genus of theropod dinosaur from the Early Cretaceous (Valanginian-aged) Cedar Mountain Formation of Utah. The type and only described species so far is N. justinhofmanni, known from at least three partial skeletons.

Podokesaurus is a genus of coelophysoid dinosaur that lived in what is now the eastern United States during the Early Jurassic Period. The first fossil was discovered by the geologist Mignon Talbot near Mount Holyoke, Massachusetts, in 1910. The specimen was fragmentary, preserving much of the body, limbs, and tail. In 1911, Talbot described and named the new genus and species Podokesaurus holyokensis based on it. The full name can be translated as "swift-footed lizard of Holyoke". This discovery made Talbot the first woman to find and describe a non-bird dinosaur. The holotype fossil was reco

Suchosaurus (meaning "crocodile lizard") is a dubious genus of large theropod dinosaur that lived during the Early Cretaceous in what is now Europe. The type species, S. cultridens, was originally described in 1841 by Richard Owen based on a chimeric assemblage of fossil teeth and vertebrae discovered in the Tilgate Forest, of Sussex, England, in sediments of the Wealden Supergroup. The second species, S. girardi, was established in 1897 by Henri Émile Sauvage from a tooth and fragmentary jaw material recovered from the Papo Seco Formation in Portugal. Initially interpreted as a crocodilian fo

Magnapaulia is a genus of herbivorous lambeosaurine hadrosaurid dinosaurs known from the Late Cretaceous (Campanian) El Gallo Formation of Baja California, northwestern Mexico. It contains a single species, Magnapaulia laticaudus, which was first described in 1981 as a possible species of Lambeosaurus by William J. Morris, and was given its own genus in 2012 by Prieto-Márquez and colleagues.

Lingwulong is a genus of diplodocoid sauropod dinosaur from the Middle Jurassic of what is now Lingwu, Yinchuan, Ningxia, China. The type and only species is L. shenqi, known from several partial skeletons. It is one of the earliest neosauropods ever discovered, as well as the only definitive diplodocoid from east Asia.

Huanansaurus is an extinct genus of oviraptorid dinosaur that lived approximately 72 million years ago, between the Campanian and Maastrichtian, during the latter part of the Cretaceous period in what is now China, in the Nanxiong Formation.

Taurovenator, from Latin taurus, meaning "bull", and venator, meaning "hunter", is an extinct genus of large, probable carcharodontosaurid theropod dinosaurs that lived in what is now Argentina during the Cenomanian age of the Late Cretaceous, around 95 to 93.9 million years ago. Initially only known from a single postorbital skull bone described from the Huincul Formation, Taurovenator violantei was named in 2016 by Argentine paleontologist Matias Motta and colleagues. Debate came about over the validity of the species, with some paleontologists arguing that Taurovenator was synonymous with t

Gryphoceratops is an extinct genus of leptoceratopsid ceratopsian dinosaur known from the Late Cretaceous of Alberta, southern Canada.

Alcovasaurus is an extinct genus of herbivorous stegosaurian dinosaurs that lived in the Late Jurassic. It was found in the Morrison Formation of Wyoming, United States. The genus contains a single species, Alcovasaurus longispinus, originally assigned to the genus Stegosaurus. It is likely a member of the Dacentrurinae, and has been referred to the genus Miragaia by some authors.

Gobihadros is a genus of basal hadrosauroid dinosaur that lived during the Late Cretaceous period in what is now the Bayanshiree Formation (dated to the Cenomanian-Santonian) of Mongolia. It contains only the type species Gobihadros mongoliensis, which has an estimated length of .

Geminiraptor (meaning "twin seizer") is a genus of troodontid theropod dinosaur that lived in North America during the Early Cretaceous period. Geminiraptor was a small, ground-dwelling bipedal carnivorous paravian. The type species of Geminiraptor is G. suarezarum.

Priconodon (meaning "saw cone tooth") is an extinct genus of ankylosaurian dinosaur (perhaps nodosaurid), mainly known from its large teeth. Its remains have been found in the Early Cretaceous (Aptian-Albian age) Arundel Formation of Muirkirk, Prince George's County, Maryland, USA, and possibly the Potomac Group, also located in Maryland. As an ankylosaur, Priconodon would have been a large armored quadrupedal herbivore, though no size estimation has been done due to the scarcity of described remains.

Lourinhasaurus is an extinct genus of herbivorous sauropod dinosaur dating from Late Jurassic strata of Estremadura, Portugal. The genus is monotypic, containing one species, Lourinhasaurus alenquerensis. The type specimen for this species was discovered near the town of Alenquer, near an abandoned mill. The specimen is housed at the Geological Museum of Lisbon. The research history of Lourinhasaurus is not without controversies, with referred specimens later being interpreted as not belonging to the genus (such as the type specimen of Supersaurus (=Dinheirosaurus) lourinhanensis). Lourinhasau

Szechuanosaurus ("Szechuan lizard") is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian-?Tithonian (Peng et al., 2005). Its type species is based on several undiagnostic teeth from the Kuangyuan Series. Additional possible specimens of Szechuanosaurus were also reported from the Kalaza Formation, also located in China.

Dyslocosaurus (meaning "hard-to-place lizard") a genus of sauropod dinosaur from the Late Jurassic Period of Wyoming, North America. The holotype or type specimen the genus is based on, AC 663, is part of the collection of the Amherst College Museum of Natural History. It was collected by professor Frederic Brewster Loomis. However, the only available information regarding its provenance is that given on the label: "Lance Creek", a county in east Wyoming. Loomis himself thought that it stemmed from the Lance Formation, dating from the Late Cretaceous (Maastrichtian).

Kerberosaurus (meaning "Kerberos lizard") is a genus of saurolophine duckbill dinosaur from the late Maastrichtian-aged (Upper Cretaceous) Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago). It is based on bonebed material including skull remains indicating that it was related to Saurolophus and Prosaurolophus.

Arkansaurus (meaning "Arkansas lizard") is an extinct genus of ornithomimosaurian theropod dinosaur that lived during the Aptian and Albian stages of the Early Cretaceous in what is now North America. The type and only species is Arkansaurus fridayi.

Daanosaurus (meaning "Da'an lizard" after Da'an district in Zigong, Sichuan) was a genus of sauropod dinosaur which lived during the Late Jurassic (Oxfordian - Tithonian stage, about 163 - 145 mya). It lived in what is now China (Sichuan Province), and was similar to Bellusaurus. Daanosaurus is known only from a partial skeleton of a juvenile, and it has been debated whether the specimen may be a juvenile mamenchisaurid.

Naashoibitosaurus (from Navajo —"creek lizard") is a genus of hadrosaurid dinosaur that lived about 73 million years ago, in the Late Cretaceous, and was found in the Kirtland Formation of the San Juan Basin in New Mexico, United States. Only a partial skeleton has been found to date. It was first described as a specimen of Kritosaurus by Jack Horner, and has been intertwined with the taxon since its description.

Qinlingosaurus is a genus of herbivorous sauropod dinosaur from the Late Cretaceous of Asia.

Lametasaurus (; ), is a chimeric genus of dinosaur known from the Lameta Formation of Jabalpur, India. The type species is L. indicus. The weight estimate of Lametasaurus, on the basis of the robust tibia, is , similar morphology can be seen in the tibia of Pycnonemosaurus, which indicates similar weight estimates.

Lophorhothon is a genus of hadrosauroid dinosaur from the Late Cretaceous of Alabama, and possibly Georgia and North Carolina. It was the first dinosaur genus discovered in Alabama, in the United States.

Daurlong (meaning "Daur dragon") is an extinct genus of dromaeosaurid dinosaur from the Early Cretaceous (Aptian) Longjiang Formation of China. The genus contains a single species, D. wangi, known from a nearly complete skeleton. Daurlong represents the first described occurrence of a preserved intestinal region in a theropod closely related to birds.

Ceratosuchops (meaning "horned crocodile face") is a genus of spinosaurid from the Early Cretaceous (Barremian) Wessex Formation of Britain. The type species is C. inferodios, known from skull fragments (a snout tip and a partial braincase) recovered between 2013–2017 from Chilton Chine on the Isle of Wight, and housed at the Dinosaur Isle Museum in Sandown. It was named in 2021 by a team consisting of Chris Tijani Barker, Darren Naish, David W. E. Hone, and colleagues, alongside Riparovenator milnerae.
