Dinosaur genera

Zapsalis is a genus of dromaeosaurine theropod dinosaurs. It is a tooth taxon, often considered dubious because of the fragmentary nature of the fossils, which include teeth but no other remains.

Velocipes (meaning "quick foot") is a genus of saurischian dinosaur from the Late Triassic that may have been a theropod. Its fossils were found in the Norian-aged Lissauer Breccia of southern Poland. Upon discovery, Velocipes was thought to have been a coelurosaur, but more recent studies have shown that Velocipes was probably a basal theropod or dinosauriform.

Tambatitanis (meaning "Tamba giant", after Tamba, the name given to the northwest of Kansai, Japan) is an extinct genus of titanosauriform, possibly titanosaurian, sauropod dinosaur from the Early Cretaceous-aged (early Albian) Ohyamashimo Formation of the Sasayama Group. It is known from a single species, Tambatitanis amicitiae, known from a partial skeleton.

Mosaiceratops is a genus of ceratopsian dinosaur that lived in the upper Cretaceous Xiaguan Formation in what is now the Henan Province of China. It was described by Zheng, Jin, and Xu in 2015 as the type species Mosaiceratops azumai. Although phylogenetic analyses have found it to be the basalmost neoceratopsian, the authors noted that several features in the premaxilla and nasal bones are shared with Psittacosaurus, indicating that neoceratopsians evolved premaxillary teeth twice and that the latter is not as primitive as previously thought.

Siluosaurus (meaning "Silu (Chinese for Silk Road, referring to the discovery location) lizard") is a genus of ornithischian dinosaur from the Early Cretaceous (Barremian-Albian) Xinminbao Group of Gansu, China. It is based on the specimen IVPP V.11117 (1-2), which consists of two teeth. It is an obscure genus, with no papers doing more than mentioning it since it was described in 1997. The type species is S. zhanggiani.

Panguraptor ("Pangu [a Chinese god] plunderer") is a genus of coelophysid theropod dinosaur known from fossils discovered in Lower Jurassic rocks of southern China. The type and only known species is Panguraptor lufengensis. The generic name refers to the deity Pangu but also to the supercontinent Pangaea for which in a geological context the same characters are used: 盘古. Raptor means "seizer", "robber" in Latin. The specific name is a reference to the Lufeng Formation. It was described in 2014 by You Hai-Lu and colleagues.

Siamodon is an extinct genus of iguanodontian ornithopod dinosaur from Early Cretaceous deposits of northeastern Thailand.

Yuanmousaurus ("Yuanmou lizard") was a sauropod dinosaur from the Middle Jurassic period of China. It is known from incomplete remains, recovered in 2000 from the Zhanghe Formation in Yuanmou County in Yunnan Province. Yuanmousaurus was a relatively large sauropod and may have reached about 17 meters (56 ft) in length. It was a basal member of the Sauropoda, but its exact systematic position is unclear. A recent study placed Yuanmousaurus within the family Mamenchisauridae. It may be a dubious genus. The only and type species was Yuanmousaurus jiangyiensis.

Riabininohadros (meaning "Riabinin's hadrosaur") is an extinct genus of ankylopollexian dinosaur from the Maastrichtian of Crimea. Its type species is Riabininohadros weberi, emended to Riabininohadros weberae. It was originally classified as a species of Orthomerus, until 2015.

Tehuelchesaurus () is a genus of macronarian sauropod dinosaur from the Late Jurassic (Oxfordian to Tithonian) of Argentina. It is named in honor of the Tehuelche people, native to the Argentinian province of Chubut, where it was first found.

Rukwatitan is a genus of titanosaur sauropod dinosaur from the Galula Formation in Tanzania. It lived around 100 million years ago, during the middle Cretaceous. The species, which shared features with another southern African species, Malawisaurus dixeyi, measured from the head to the tip of the tail, and had forelimbs that were estimated around long. Its fossils were found embedded in a cliff face near Lake Rukwa in the Rukwa Valley, from which it gets its name.

Rativates is a genus of ornithomimid theropod dinosaur from the Campanian-aged (Late Cretaceous) Dinosaur Park Formation of Alberta, Canada. The type species is Rativates evadens.

Pradhania (named after Dhuiya Pradhan, a fossil collector at the Indian Statistical Institute) is a genus of massospondylid sauropodomorph dinosaur from the Sinemurian-age (Early Jurassic) Upper Dharmaram Formation of India. It was first named by T. S. Kutty, Sankar Chatterjee, Peter M. Galton and Paul Upchurch in 2007 and the type species is Pradhania gracilis. It was a sauropodomorph of modest size, only about four meters (13 ft) long, and is known from fragmentary remains. It was originally regarded as a basal sauropodomorph but new cladistic analysis performed by Novas et al., 2011 su

Planicoxa is a genus of advanced iguanodontian dinosaur from the Early Cretaceous of North America. It is known from the partial skeletons of several individual specimens. Its fossils were discovered in Utah, United States.

Martharaptor is a genus of therizinosauroid theropod dinosaurs from the Early Cretaceous of the Cedar Mountain Formation in Utah. They can be distinguished from other therizinosauroids by means of several features of the skeleton (particularly the hands and feet) which were intermediate between early therizinosaurs such as Falcarius and Beipiaosaurus, and more "advanced" members of the group like therizinosaurids. The deep and homogeneous hand claws clearly differ from the case in early therizinosauroids, but the foot has not yet acquired the robust morphology of therizinosaurids.

Clasmodosaurus (meaning "fragmentary tooth reptile") is a genus of titanosaurian sauropod dinosaur from the Mata Amarilla Formation and the Cerro Fortaleza Formation. It lived during the Late Cretaceous in what is now Argentina. It is known from five fossilized and assorted teeth, but is diagnosed by a unique combination of characters.

Jintasaurus (; meaning "Jinta County dragon") is a genus of hadrosauriform dinosaur that lived during the Early Cretaceous of what is now Jiuquan, Gansu, northwestern China. The type species is J. meniscus, described by Hai-Lu You and Da-Qing Li in 2009. The holotype and only known specimen includes the postorbital skull, lacking the jugal and quadratojugal, whose discovery supports the theory that hadrosaurs originated in Asia.

Huehuecanauhtlus is a genus of hadrosauroid dinosaur known from the Late Cretaceous (Santonian stage) of Michoacán, western Mexico. It contains a single species, Huehuecanauhtlus tiquichensis.

Guemesia (named after Martín Miguel de Güemes, whose death bicentenary was in 2021) is a genus of abelisaurid dinosaur from the Late Cretaceous Los Blanquitos Formation of Salta Province, Argentina. The type and only species is Guemesia ochoai, known from a nearly complete braincase. It is one of the smallest abelisaurids currently known.

Bienosaurus (meaning "Boien's lizard) is a dubious genus of thyreophoran dinosaur from the Early Jurassic (probably Hettangian to Sinemurian) Lower Lufeng Formation of Yunnan Province in China.

Ledumahadi (meaning "giant thunderclap" in Sesotho language) is a genus of lessemsaurid sauropodomorph dinosaur from the Early Jurassic Elliot Formation in Free State Province, South Africa. The type and only species is L. mafube, known from a singular incomplete postcranial specimen.

Nebulasaurus is an extinct genus of basal eusauropod dinosaur known from the early Middle Jurassic Zhanghe Formation (Aalenian or Bajocian stage) of Yunnan Province, China. It is known only from the holotype braincase LDRC-v.d.1. A phylogenetic analysis found Nebulasaurus to be a sister taxon to Spinophorosaurus from the Middle Jurassic of Africa. This discovery is significant paleontologically because it represents a clade of basal eusauropods previously unknown from Asia.

Phaedrolosaurus (meaning "elated lizard") is a dubious genus of coelurosaurian (perhaps dromaeosaurid) theropod dinosaur, based on an isolated and non-diagnostic tooth from the Early Cretaceous Lianmuqin Formation of Wuerho, in the autonomous region of Xinjiang, China.

Overosaurus (meaning "Overo lizard", after the Cerro Overo locality) is an extinct genus of sauropod dinosaurs, containing only a single species, Overosaurus paradasorum. This species lived approximately 86 to 84 million years ago during the latter part of the Cretaceous Period in what is now Patagonia (in southern Argentina). Overosaurus paradasorum was relatively small compared to other sauropods from Patagonia, like the saltasaurids and other aeolosaurines, estimated as approximately . It was a ground-dwelling herbivore.

Iuticosaurus (meaning "Jute lizard") is a genus of titanosaur sauropod dinosaur from the Early Cretaceous of the Isle of Wight. Two species have been named: I. valdensis and I. lydekkeri. I. valdensis was found in the Wessex Formation and I. lydekkeri in the younger Upper Greensand.

Imperobator ("powerful warrior") is a genus of probable unenlagiid paravian theropod dinosaurs, that lived during the Maastrichtian age of the Late Cretaceous in what is now James Ross Island in Antarctica. Imperobator is one of only two non-avian theropods known from Antarctica, crossing over to the landmass when it was part of Gondwana. The only described specimen was found in 2003 by an expedition launched by the University of California Museum of Paleontology and initially described as a dromaeosaur in 2007. The fossil was formally described as a new genus in 2019, and later searches repor

Epichirostenotes (meaning "above Chirostenotes", because it lived after the latter genus) is a genus of oviraptorosaurian dinosaur from the Late Cretaceous. Epichirostenotes is known from an incomplete skeleton found in 1923 at the Horseshoe Canyon Formation, in strata dated to about 72 million years ago. It was first named by Robert M. Sullivan, Steven E. Jasinski and Mark P.A. van Tomme in 2011 and the type species is Epichirostenotes curriei. Its holotype, ROM 43250, had been assigned to Chirostenotes pergracilis by Hans-Dieter Sues in 1997.

Wulagasaurus (meaning "Wulaga lizard", in reference to the discovery locality) is a genus of saurolophine hadrosaurid dinosaur from the Late Cretaceous of Heilongjiang, China.

Yingshanosaurus (meaning "Yingshan lizard") is an extinct genus of stegosaurian dinosaurs from the Middle Jurassic of what is now Southwestern China. It is known from a partial skeleton discovered in 1983, including back, sacrum, and tail vertebrae, forelimb and hindlimb bones, shoulder and hip bones, and several osteoderms, including plates and a shoulder spine. The genus contains a single species, Yingshanosaurus jichuanensis, named and described in 1994. For some time after its discovery and scientific description, many paleontologists were unaware of the Chinese research published on it an

Joaquinraptor (; ) is an extinct genus of megaraptorid theropod dinosaurs known from the Late Cretaceous Lago Colhué Huapi Formation of Argentina. The genus contains a single species, Joaquinraptor casali, representing the youngest (most recent) definitive megaraptoran. It is known from a partially articulated, incomplete skeleton including vertebrae and bones of the skull, forelimbs and hindlimbs, and pectoral girdle, making it one of the most completely known members of the Megaraptora. It was likely at least long.

Pitekunsaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Anacleto Formation of Neuquén, Argentina. It was described by L. Filippi and A. Garrido in 2008. The type species is P. macayai. The generic name is derived from Mapudungun pitekun, meaning "to discover", the epitheton honours the discoverer, oil company explorer Luis Macaya, who found the fossil in April 2004.

Viavenator (meaning "road hunter") is a genus of carnivorous abelisaurid theropod dinosaur that lived in the Santonian-aged (Late Cretaceous) Bajo de la Carpa Formation of Argentina. Only a single species is known, V. exxoni, formally described in 2016 by Filippi and colleagues.

Xianshanosaurus () is a genus of sauropod dinosaur from the Early Cretaceous (Aptian-Albian) of the Ruyang Basin in Henan Province, China. Its type and only species is Xianshanosaurus shijiagouensis. It was described in 2009 by a team of paleontologists led by Lü Junchang. Xianshanosaurus may be a titanosaur, and Daxiatitan may be its closest relative, but its evolutionary relationships remain controversial.

Dzharatitanis (meaning "Dzharakuduk titan") is an extinct genus of probable titanosaurian sauropod dinosaur from the Late Cretaceous (Turonian age) Bissekty Formation of Uzbekistan. The genus contains a single species, Dzharatitanis kingi, known from a single tail vertebra. Dzharatitanis was considered to be a member of the Rebbachisauridae when it was named in 2021, but subsequent research has considered it to be a titanosaur.

Xixiposaurus (meaning "Xixipo lizard") is a genus of "prosauropod" dinosaur which existed in what is now Lower Lufeng Formation, China during the lower Jurassic period. It was first named by Sekiya Toru in 2010 and the type species is X. suni.

Apatodon is a dubious genus of dinosaur that may have been a theropod. The type, and only species, A. mirus, was named in 1877 by Othniel Charles Marsh. It was found in the Late Jurassic-aged Morrison Formation of Colorado.

Shidaisaurus is a genus of metriacanthosaurid dinosaur. Its fossil was found in early Middle Jurassic-age rocks of the Chuanjie Formation in Yunnan, China. It is known from a partial skeleton, holotype DML-LCA 9701-IV, found at the bottom of an assemblage of nine dinosaur individuals, lacking most of the tail vertebrae, ribs, pectoral girdle, and limb bones. Shidaisaurus was described in 2009 by Wu and colleagues. The type species is Shidaisaurus jinae. Generic name and specific name in combination refer to the Jin-Shidai ("Golden Age") Company that oversaw excavation and inspection of the Jur

Batyrosaurus is an extinct genus of herbivorous basal hadrosauroid dinosaur known from the Late Cretaceous Bostobe Formation (Santonian to Campanian stage) of central Kazakhstan. It contains a single species, Batyrosaurus rozhdestvenskyi. It is possible that Batyrosaurus represents the same taxon as the doubtful Arstanosaurus akkurganensis as both were found from the same formation.

Loricosaurus (meaning "armor lizard") is a genus of sauropod represented by a single species, L. scutatus. It is a titanosaur that lived near the end of the Late Cretaceous period, approximately 71 million years ago in the early Maastrichtian, being found in the province of Neuquen, Argentina in the Allen Formation. Due to the presence of armor, at first it was believed that it was an ankylosaur, but today it is considered to be that of a titanosaur.

Ibirania (meaning "Ibirá wanderer" or "tree wanderer") is a genus of dwarf saltasaurine titanosaur dinosaur from the Late Cretaceous (Santonian to Campanian) São José do Rio Preto Formation (Bauru Basin) of Southeast Brazil. The type species is Ibirania parva. It is one of the smallest sauropods known to date, comparable in size to the titanosaur Magyarosaurus.

Inosaurus (meaning "In Tedreft lizard") is a dubious genus of extinct theropod dinosaur from the Early Cretaceous age "Continental intercalaire" and Echkar Formation of Niger and possibly from the Late Cretaceous age Baharija Formation of Egypt. The type, and only species, is I. tedreftensis.

It is known from specimen GMNH F10001 which consists of a single, nearly complete dorsal vertebra and a mid-caudal vertebra. Gannansaurus was first named by Lü Junchang, Yi Laiping, Zhong Hui and Wei Xuefang in 2013 and the type species is Gannansaurus sinensis. Gannansaurus shares some characters with Euhelopus, indicating that it is more closely related to it rather than to other titanosaurifo

Uteodon (meaning "Ute tooth") is a genus of herbivorous iguanodontian dinosaur. It is a basal iguanodontian which lived during the late Jurassic period (Tithonian age) in what is now Uintah County, Utah. It is known from the middle of the Brushy Basin Member, Morrison Formation. The genus was named by Andrew T. McDonald in 2011 and the type species is U. aphanoecetes. ==History== The holotype specimen, CM 11337 (a virtually complete skeleton minus the skull and tail), was assigned to Camptosaurus medius (Marsh, 1894) by Charles W. Gilmore in 1925. When C. medius was synonymised with Camptosaur

Sonidosaurus (meaning "Sonid lizard", after Sonid, the large geographical area that includes the type locality) is a genus of sauropod dinosaur from the Late Cretaceous. It was a titanosaur which lived in what is now Inner Mongolia. The type species, Sonidosaurus saihangaobiensis, was described by Xu, Zhang, Tan, Zhao, and Tan in 2006. It was a small titanosaur, about 9 meters (30 ft) long. It was first discovered in the Saihangaobi, Iren Dabasu (Erlian) Formation, in 2001 in a quarry which would later yield the remains of Gigantoraptor.

Diplotomodon (meaning "double cutting tooth") is a dubious genus of theropod dinosaur, from New Jersey. It was possibly a member of the Tyrannosauroidea, the clade that also contains Tyrannosaurus.

Tsagantegia (; meaning Tsagan Teg) is a genus of medium-sized ankylosaurid thyreophoran dinosaur that lived in Asia during the Late Cretaceous period. The genus is monotypic, including only the type species, T. longicranialis. The specimen consists of a very partial individual, comprising the skull and lacking postcranial remains. Since it only preserves the skull, Tsagantegia is mainly characterized by its elongated snout and the flattened facial osteoderms, greatly differing from other ankylosaurs. ==Discovery and naming== The first, and only, discovery of Tsagantegia fossils occurred in 198

Stegopelta (meaning "roofed shield") is a genus of struthiosaurin nodosaurid dinosaur based on a partial skeleton from the Cretaceous (latest Albian-earliest Cenomanian) Belle Fourche Member of the Frontier Formation of Fremont County, Wyoming, USA.

Tianzhenosaurus (meaning “Tianzhen lizard”) is a genus of ankylosaurid dinosaurs known from the Late Cretaceous Huiquanpu Formation of Shanxi Province, China. The genus contains two species, T. youngi (the type species) and T. chengi. Some researchers have suggested that Tianzhenosaurus may represent a junior synonym of Saichania, an ankylosaurine from the Barun Goyot and Nemegt formations.

Duonychus (meaning "two claws") is an extinct genus of therizinosaurid theropod dinosaurs that lived during the Late Cretaceous (Cenomanian to early Coniacian age) of what is now Mongolia. It is known from a partial skeleton, including several vertebrae, most of the forelimbs, and part of the pelvic girdle, found in outcrops of the Bayanshiree Formation. The remains were discovered in 2012 by the Mongolian Academy of Sciences and briefly mentioned in later conference abstracts. The genus contains a single species, Duonychus tsogtbaatari, which was formally described in 2025.

Terminocavus is a genus of ceratopsid dinosaur from the late Cretaceous Period of what is now North America. The genus contains a single species, the type species Terminocavus sealeyi, known from a parietal and some other associated fragments. The holotype specimen was discovered in the Kirtland Formation of New Mexico in 1997, and was later described and named in a 2020 study. It was similar in anatomy to Pentaceratops and Anchiceratops, which it was closely related to, but had a distinctive heart-shaped upper frill with very narrow notch. It has been hypothesized to form an anagenetic series

Spectrovenator ("ghost hunter") is a genus of basal abelisaurid theropod dinosaur that lived during the early Cretaceous period in what is now Brazil. The type and only known species is S. ragei, representing a small abelisaurid about long.

Choyrodon is a genus of hadrosauroid dinosaur from the Early Cretaceous (Albian) Khuren Dukh Formation of Mongolia. The type and only species is Choyrodon barsboldi. The generic name is derived from the city of Choyr, and -odon, from Latin for tooth; the specific name barsboldi honours paleontologist Rinchen Barsbold. The material consists of a holotype partial skull and cervical ribs, with two other partial skulls both with associated postcranial material. It was found to be the sister taxon of Eolambia.

Xiyunykus (meaning "western claw"; "xiyu" is Mandarin for "west" and refers to Western China where it was found) is a genus of alvarezsauroid theropod from the Early Cretaceous-aged Tugulu Group of what is now China. Only one species has been described, Xiyunykus pengi.

Patagopelta (meaning "Patagonian shield") is an extinct genus of ankylosaurian dinosaur from the Late Cretaceous (upper Campanian–lower Maastrichtian) Allen Formation of Argentina. The genus contains a single species, P. cristata, known from several partial skeletons, isolated bones, and osteoderms. While originally described as a member of the family Nodosauridae, later discoveries provided support for parankylosaurian affinities. Patagopelta is a small armored dinosaur, comparable in size to the 'dwarf' nodosaurid Struthiosaurus, at about long. It is larger, more robust, and more heavily arm
