Dinosaur genera

Stegouros (, meaning "roofed tail") is an extinct genus of ankylosaurian dinosaurs from the Late Cretaceous Dorotea Formation of southern Chile. The genus contains a single species, Stegouros elengassen, known from a semi-articulated, near-complete skeleton. Stegouros is a member of the Parankylosauria, a clade of small Gondwanan armored dinosaurs. It is characterized by its small body size and distinct arrangement of fused osteoderms forming a macuahuitl-like tail weapon.

Jubbulpuria ("Jubbulpore one") is the name given to a dubious genus of theropod dinosaur from the Late Cretaceous Lameta Formation of India.

Pararhabdodon (meaning "near fluted tooth" in reference to Rhabdodon) is a genus of tsintaosaurin hadrosaurid dinosaur from the Maastrichtian-aged (Late Cretaceous) Tremp Group of Spain. The first remains were discovered from the Sant Romà d'Abella fossil locality and assigned to the genus Rhabdodon, and later named as the distinct species Pararhabdodon isonensis in 1993. Known material includes assorted postcranial remains, mostly vertebrae, as well as from the skull. Specimens from other sites, including remains from France, a maxilla previously considered the distinct taxon Koutalisaurus ko

Levnesovia is a genus of hadrosauroid dinosaur from the Late Cretaceous (Turonian) Bissekty Formation of Uzbekistan. It was related to Bactrosaurus. The type species is L. transoxiana. The genus name honours the late Russian paleontologist Lev Nessov, and the specific name refers to the ancient region Transoxiana. It is known from partial skulls, maxillae, dentaries and numerous bones of the postcranial skeleton.

Elrhazosaurus (meaning "Elrhaz lizard") is a genus of basal iguanodontian dinosaur, known from isolated bones found in Early Cretaceous rocks of Niger. These bones were initially thought to belong to a species of the related dryosaurid Valdosaurus, but have since been reclassified.

Tianchisaurus (meaning "heavenly pool lizard"), also invalidly called Tianchiasaurus and "Jurassosaurus", is a genus of ankylosaurian dinosaur from the Late Jurassic (Oxfordian-Kimmeridgian) Toutunhe Formation of China. While many later-diverging ankylosaurids had bony clubs at the tips of their tails, Tianchisaurus likely lacked such a structure.

Dryptosauroides (meaning "similar in form to Dryptosaurus") is a dubious genus of possibly abelisauroid theropod dinosaur from the Late Cretaceous (Maastrichtian) Lameta Formation of India. It has been estimated at long and in weight.

Moabosaurus (meaning "Moab reptile") is a genus of turiasaurian sauropod dinosaur from the Early Cretaceous Cedar Mountain Formation of Utah, United States.

Dolichosuchus (meaning "long crocodile") is the name given to a genus of dinosaur from the Triassic. It was originally classified in the disused family Hallopodidae, but has since been reclassified as a coelophysoid. A single fossil (consisting of a single lower leg bone, or tibia) was found in Germany (specimen NHMUK PV OR 38058). Since only one bone was discovered, the genus is considered a nomen dubium. Some scientists have noted that the tibia closely resembles those of Liliensternus and Dilophosaurus.

Ahvaytum ( ; ) is an extinct genus of probable basal sauropodomorph saurischian dinosaurs from the Late Triassic Popo Agie Formation of Wyoming, United States. The genus contains a single species, A. bahndooiveche, known from fragmentary hindlimb bones. Ahvaytum represents the oldest known named dinosaur of the ancient Laurasian landmass.

Abdarainurus (meaning "Abdrant Nuru tail" after the holotype locality) is a genus of titanosaur dinosaur from the Alagteeg Formation in Mongolia. The type and only species is A. barsboldi. Currently seen as an indeterminate titanosaur, it may represent a previously unknown lineage of Asian macronarians. Abdarainurus is not known from many remains; it is only known from eight front tail vertebrae and a middle tail vertebra and several chevrons.

Corythoraptor () is a genus of oviraptorid dinosaur from the late Maastrichtian Nanxiong Formation of South China. It contains one species, C. jacobsi, known from a single well-preserved skeleton, and named after paleontologist Louis L. Jacobs. It bears a tall crest similar to that of the modern cassowary, and possibly had a similar functionality of display and resonance to detect lower-frequency sounds.

Dongbeititan is a genus of sauropod dinosaur from the Early Cretaceous Yixian Formation of Beipiao, Liaoning, China. It is based on holotype DNHM D2867, a partial postcranial skeleton including bones from the limbs, shoulder and pelvic girdles, and vertebrae, which was described in 2007. Its describers suggested it was as a basal titanosauriform, not as derived as Gobititan or Jiutaisaurus, but more derived than Euhelopus, Fusuisaurus, and Huanghetitan. The type species is D. dongi, and it is the first named sauropod from the Yixian Formation, which is part of the well-known Jehol Group. The g

Xuwulong is a genus of hadrosauroid dinosaur from the Early Cretaceous period of what is now Yujingzi Basin in the Jiuquan area, Gansu Province of northwestern China. It is known from the holotype, GSGM F00001, an articulated specimen including a complete cranium, almost complete axial skeleton, and complete left pelvic girdle recovered from the Xinminbao Group. Xuwulong was named by You Hailu, Li Daqing, and Liu Weichang in 2011, and the type species is Xuwulong yueluni; the binomial name as a whole refers to Professor Wang Yue-lun; "Xu-wu" is his courtesy name.

Euskelosaurus ("good leg lizard") is a sauropodomorph dinosaur from the Late Triassic of South Africa and Lesotho. Fossils have only been recovered from the lower Elliot Formation in South Africa and Lesotho, and in one locality in Zimbabwe.

Galvesaurus, or Galveosaurus (meaning "Galve lizard"), is a genus of brachiosaurid sauropod dinosaur from the Late Jurassic period. Fossils of the only known species, G. herreroi, were found in Galve, Spain, hence its generic name. The specific name herreroi honours the discoverer, José María Herrero. Some researchers suggest that the taxon might represent a junior synonym of the Portuguese genus Lusotitan.

Yixianosaurus (meaning "Yixian lizard") is a maniraptoran theropod dinosaur genus from the Early Cretaceous of China.

Craterosaurus (meaning krater reptile or bowl reptile) is a dubious genus of stegosaurian dinosaur that lived during the Early Cretaceous (possibly Aptian stage) of the Woburn Sands Formation of England. Estimated to measure around in length and weighing approximately , Craterosaurus may actually be a junior synonym of Regnosaurus, but only one fossil, a partial vertebra, was recovered.

Sauroplites (meaning "saurian hoplite") is a genus of herbivorous ankylosaurian dinosaur from the Early Cretaceous of China.

Arcovenator ("Arc hunter") is an extinct genus of abelisaurid theropod dinosaurs hailing from the Late Cretaceous of France and possibly Spain. The type and only described species is Arcovenator escotae. Its name derives from the river Arc flowing near the site of its first discovery.

Heptasteornis is a dubious genus of alvarezsaurid dinosaur from the Late Cretaceous. The type (and only known) species is Heptasteornis andrewsi, described as a presumed gigantic prehistoric owl in 1975. It was previously included in Elopteryx nopcsai and indeed the holotypes of both species were believed to be from the same individual as they were discovered, and initially were assigned the same specimen number. This appears to be in error however (see below).

Arackar (meaning "skeleton" in Kunza) is an extinct genus of lithostrotian sauropod, possibly part of the Saltasauridae, discovered in the Hornitos Formation of Atacama Province, Chile. The genus contains a single species, Arackar licanantay, described by Rubilar-Rogers et al. in 2021.

Erectopus (meaning "upright foot") is an extinct genus of basal allosauroid theropod from the Early Cretaceous La Penthiève Beds Formation of France and also possibly the Cernavodă Formation of southern Romania. The type species is E. superbus, which was initially known as a species of Megalosaurus.

Dystrophaeus is an extinct genus of sauropod dinosaur. Its type and only species is Dystrophaeus viaemalae, named by Edward Drinker Cope in 1877. Its fossils were found in the Tidwell Member of the Morrison Formation of Utah. Due to the fragmentary condition of its only known specimen, the affinities of Dystrophaeus are uncertain, although excavations carried out at the discovery site since 1989 have uncovered more of the original specimen and hold the potential for an improved understanding of the taxon.

Alpkarakush is an extinct genus of metriacanthosaurid theropod dinosaurs from the Jurassic Balabansai Formation of Kyrgyzstan. The genus contains a single species, A. kyrgyzicus, known from a partial skeleton.

Sarmientosaurus is a genus of titanosaurian sauropod dinosaur belonging to the Titanosauria. It lived in what is now South America, specifically Argentina, during the Upper Cretaceous Period about 95 million years ago. The type species is Sarmientosaurus musacchioi.

Duriatitan is a genus of titanosauriform sauropod dinosaur that lived in the Late Jurassic in what is now England. The holotype specimen of Duriatitan, BMNH 44635, is a partial left upper arm bone which was found by R.I. Smith near Sandsfoot, Weymouth in the lower Kimmeridge Clay from Dorset. The type species, D. humerocristatus, was described in 1874 by John Hulke as a species of Cetiosaurus and was noted as being similar to that of Gigantosaurus. The specific name refers to the deltopectoral crest, crista, on the upper arm bone, humerus. The specimen was assigned to its own genus by Pau

Stellasaurus (meaning "star lizard"; both in reference to the shape of its head ornamentation and as an homage to the song "Starman" by David Bowie) is a genus of centrosaurine ceratopsid dinosaur that lived in Montana during the Late Cretaceous. The type and only species is Stellasaurus ancellae. Its remains have been found in the late Campanian-aged Two Medicine Formation, the same geological unit which its relatives Rubeosaurus (now seen as a synonym of Styracosaurus), Einiosaurus, and Achelousaurus were discovered in.

Sinusonasus is a genus of dinosaurs from the Early Cretaceous Period, recovered from the Yixian Formation. It lived in what is now the Liaoning Province of China. Sinusonasus was a theropod, specifically a troodontid dinosaur.

Boreonykus is an extinct genus of dromaeosaurid dinosaur, that lived during the Late Cretaceous in the area of present Canada.

Chuxiongosaurus (meaning "Chuxiong lizard") is a genus of basal sauropodomorph dinosaur which lived during the Early Jurassic Period. Fossils of this genus have been found in the Lower Lufeng Formation, Yunnan Province, southern China. Identified from the holotype CMY LT9401 a nearly complete skull (including a lower jaw) with some similarities to Thecodontosaurus, it was described as the "first basal sauropod dinosaur from the Early Jurassic of China," more basal than Anchisaurus. It was named by Lü Junchang, Yoshitsugu Kobayashi, Li Tianguang and Zhong Shimin in 2010, and the type species is

Bisticeratops (meaning "Bisti/De-Na-Zin Wilderness horned face") is a genus of chasmosaurine ceratopsian from outcrops of the Campanian age Kirtland Formation found in the Bisti/De-Na-Zin Wilderness in northwestern New Mexico, United States. The type and only species is B. froeseorum, known from a nearly complete skull.

Laosaurus (meaning "stone or fossil lizard") is a genus of neornithischian dinosaur. The type species, Laosaurus celer, was first described by O.C. Marsh in 1878 from remains discovered in the Upper Jurassic (Kimmeridgian) Morrison Formation of Wyoming. The validity of this genus is doubtful because it is based on fragmentary fossils. A second species also from the Morrison Formation, L. gracilis, and a species from the Upper Cretaceous Allison Formation of Alberta, Canada, L. minimus, are also considered dubious.

Hualianceratops is a genus of herbivorous ceratopsian dinosaur that lived about 160 million years ago in the Late Jurassic epoch in what is now western China. The single species, H. wucaiwanensis was described in 2015. Its size has been compared to that of a spaniel.

Protathlitis (meaning "champion") is a potentially dubious and chimeric genus of theropod dinosaur from the Early Cretaceous (Barremian) Arcillas de Morella Formation of Castellón, Spain. The type and only species is Protathlitis cinctorrensis, known from a partial skeleton. It was originally identified as a basal member of the Baryonychinae. If a spinosaurid identity of the material is correct, its discovery, as well as those of the spinosaurids Camarillasaurus, Iberospinus, Riojavenatrix, and the contemporary Vallibonavenatrix shows that the Iberian Peninsula held a diverse assemblage of the

Ngwevu is a genus of massospondylid sauropodomorph dinosaur from the Lower Jurassic of South Africa. The genus contains one species, Ngwevu intloko.

Rhinorex is a genus of kritosaurin hadrosaur from the Late Cretaceous Neslen Formation, in central Utah. Its exact placement in time is uncertain, though it probably dates to 75 million years ago and was discovered in estuarine sediments.

Mexidracon (meaning "Mexican dragon") is an extinct genus of ornithomimid theropod dinosaurs from the late Cretaceous Cerro del Pueblo Formation of Coahuila, Mexico. The genus contains a single species, M. longimanus, known from a partial skeleton. Mexidracon is the second ornithomimosaur to be named from this formation, following the deinocheirid Paraxenisaurus in 2020.

Pukyongosaurus (meaning "Pukyong lizard", after the Pukyong National University) is a genus of titanosauriform dinosaur that lived in South Korea during the Early Cretaceous Period (Aptian - Albian). It may have been closely related to Euhelopus, and is known from a series of vertebrae in the neck and back. The characteristics that were originally used to distinguish this genus have been criticized as being either widespread or too poorly preserved to evaluate, rendering the genus an indeterminate nomen dubium among titanosauriforms. A 2022 study noted that Pukyongosaurus is probably a somphos

Osmakasaurus (meaning "canyon lizard", ósmaka meaning "canyon" in the Lakota language) is a genus of iguanodontian dinosaur which lived in the Early Cretaceous (Valanginian age) Chilson Member of the Lakota Formation in what is now Buffalo Gap of South Dakota, United States. This genus was named by Andrew T. McDonald in 2011 and the type species is O. depressus.

Elaltitan is an extinct genus of large lithostrotian titanosaur sauropod dinosaur known from the Late Cretaceous (mid Cenomanian to Turonian stage) of Chubut Province, southern Argentina. It contains a single species, Elaltitan lilloi.

Chinshakiangosaurus (JIN-shah-jiahng-uh-SOR-us, meaning "Chinshakiang lizard") is a genus of basal sauropod dinosaur. The only species, Chinshakiangosaurus chunghoensis, is known from a fragmentary skeleton found in Early Jurassic rocks in China. It is one of the few basal sauropods with preserved skull bones and therefore important for the understanding of the early evolution of this group, and also shows that early sauropods may have possessed fleshy cheeks.

Cathartesaura is a genus of rebbachisaurid sauropod dinosaur from Late Cretaceous strata of the Huincul Formation, at the "La Buitrera" locality, in the Neuquén Basin of Río Negro Province, Argentina. The fossil remains, described by Gallina and Apesteguía in 2005, consist of a partial skeleton including vertebrae and limb bones. These were found at the base of the formation, which dates back to the Cenomanian and Turonian epochs, in mudstone and sandstone levels.

Kaijiangosaurus (meaning "Kaijiang lizard") is a genus of carnivorous tetanuran theropod dinosaur from the Middle Jurassic of China. In 1984 He Xinlu named and described the type species Kaijiangosaurus lini. The generic name refers to the River (jiang) Kai. The specific name honours the paleontologist Lin Wenqiu.

Pellegrinisaurus (meaning Lizard from Pelligrini) is a genus of titanosaurian sauropod dinosaur that lived in South America during the Late Cretaceous period. The holotype was found in the Allen Formation, Argentina.

The type species is L. liudianensis. Holtz estimated it at and around . Molina-Pérez and Larramendi gave a similar size of and .

Shuangmiaosaurus is a genus of herbivorous iguanodontian ornithopod dinosaur which lived in China during the Late Cretaceous Period, about 100 million years ago.

Histriasaurus (HIS-tree-ah-SAWR-us) (meaning "Istria lizard") is a genus of sauropod dinosaur from the Early Cretaceous (Hauterivian to Barremian stages, around 135-125 million years ago) of Croatia. It has been suggested to be a rebbachisaurid, and if so one of the oldest known members of the group.

Glyptodontopelta (meaning "Glyptodon shield") is a monospecific genus of nodosaurid dinosaur from New Mexico that lived during the Late Cretaceous (lower to upper Maastrichtian, 69 to 66 Ma) in what is now the Naashoibito member of the Ojo Alamo Formation. The type and only species, Glyptodontopelta mimus, is known from numerous specimens that consist of osteoderms, a dentary, supraorbital and bone fragments. It was named in 2000 by Tracy Ford. Edmontonia australis is a junior synonym of Glyptodontopelta.

Asfaltovenator (meaning "Cañadón Asfalto Formation hunter" after the fossil formation in which its fossils were found) is a genus of possibly allosauroid dinosaur from the Lower Jurassic (Middle Toarcian) Cañadón Asfalto Formation of Chubut Province, Argentina. The type and only species is Asfaltovenator vialidadi.
