Dinosaur genera

Piveteausaurus (meaning "Jean Piveteau's lizard") is a genus of theropod dinosaur known from a partial skull discovered in the Middle Jurassic (164.7 to 161.2 million years ago) Marnes de Dives of Calvados, northern France. In 2012, Thomas Holtz gave a possible length of .

Laquintasaura is a genus of Venezuelan ornithischian dinosaur containing a single species, Laquintasaura venezuelae. It is known for being one of the most primitive ornithischians in the fossil record, as well as the first dinosaur to have been identified from Venezuela. The name is derived from the La Quinta Formation, where it was discovered, and the feminine Greek suffix for lizard, with the specific name referring to the country of Venezuela. It is known from hundreds of fossil elements, all derived from a single extensive bonebed locality. Initially discovered by French palaeontologists,

Austrosaurus (; ) was an extinct genus of sauropod dinosaur from the Allaru Formation, dated to the early Cretaceous (112-100 million years ago), of Central-Western Queensland in Australia. Several specimens are known.

Serendipaceratops (meaning "serendipitous horned face") is a genus of herbivorous ornithischian dinosaur, possibly an ankylosaur, from the early Cretaceous Period of Australia. The type species, S. arthurcclarkei, was named in 2003.

Fukuisaurus (meaning "Fukui (Fortunate) lizard") is a genus of herbivorous ornithopod dinosaur that lived during the Early Cretaceous in what is now Japan. The type species is F. tetoriensis, which was named and described in 2003.

Mirischia is an extinct genus of coelurosaurian theropod dinosaur from the Albian stage (Early Cretaceous Period) of northeastern Brazil.

Gobisaurus is an extinct genus of herbivorous basal ankylosaurid ankylosaur from the Lower Cretaceous of China (Nei Mongol Zizhiqu). The genus is monotypic, containing only the species Gobisaurus domoculus.

Sciurumimus ("squirrel mimic," named for its tail's resemblance to that of the tree squirrel genus Sciurus) is an extinct genus of tetanuran theropod from the Late Jurassic Torleite Formation of Germany. It is known from a single juvenile specimen representing the type species, Sciurumimus albersdoerferi, which was found in a limestone quarry close to Painten in Lower Bavaria. The specimen was preserved with traces of feather-like filaments.

Unaysaurus is a genus of herbivorous unaysaurid sauropodomorph dinosaur. Discovered in southern Brazil, in the geopark of Paleorrota, in 1998, and announced in a press conference on Thursday, December 3, 2004, it is one of the oldest dinosaurs known. It is closely related to plateosaurid dinosaurs found in Germany, which indicates that it was relatively easy for species to spread across the giant landmass of the time, the supercontinent of Pangaea. The fossils of Unaysaurus are well-preserved. They consist of an almost complete skull, including a lower jaw, and partial skeleton with many of th

Linhenykus is an extinct genus of alvarezsaurid theropod dinosaur from the Late Cretaceous of Inner Mongolia, China. It is the most basal known member of the Parvicursorinae. The genus gets its name from Linhe, a city near the site where the fossil was first found and Greek nykus, "claw". The specific name is derived from Greek monos, "single", and daktylos, "finger", a reference to the fact that it is the only known non-avian dinosaur to have had but a single digit.

Graciliceratops (meaning "slender horned face") is a genus of neoceratopsian dinosaurs that lived in Asia during the Late Cretaceous period.

Xuanhanosaurus (meaning "Xuanhan lizard") is a genus of theropod dinosaur that lived during the Middle Jurassic (Bathonian) of the Sichuan Basin, China, around 166 million years ago. This taxon represents one of the various non-coelurosaurian tetanuran taxa found on the Middle Jurassic of the region, uncovered in the Lower Shaximiao Formation. Although it has been known for more than 40 years, this taxon has been the subject of very few studies, although most seem to agree that it is a tetanuran, possibly a basal allosauroid, highlighting the fact that it has a vestigial fourth metacarpal.

Brontomerus (from Greek bronte meaning "thunder", and merós meaning "thigh") is a genus of camarasauromorph sauropod which lived during the early Cretaceous (Aptian or Albian age, approximately 110 million years ago). It was named in 2011 and the type species is Brontomerus mcintoshi. It is probably a fairly basal camarasauromorph, though the taxon is difficult to resolve due to incompleteness of the material. It is most remarkable for its unusual hipbones, which would have supported the largest thigh muscles, proportionally, of any known sauropod. The specific name is in honor of physicist an

Eosinopteryx is an extinct genus of theropod dinosaurs known to the Late Jurassic epoch of China. It contains a single species, Eosinopteryx brevipenna. Some researchers consider it a junior synonym of Anchiornis.

Chuandongocoelurus ( ) is a genus of carnivorous tetanuran theropod dinosaur from the Jurassic of China.

Wakinosaurus (meaning "Wakino lizard") is a genus of possible carcharodontosaurid theropod dinosaur from the Early Cretaceous (Valanginian-Barremian) Sengoku Formation of Kyushu, Japan. The genus is a tooth taxon, based solely on the middle section of a single tooth.

Zhuchengceratops is a genus of extinct leptoceratopsid ceratopsian that lived during the Upper Cretaceous of modern-day China. It was first described in 2010, by Xu et al., who created the binomial Zhuchengceratops inexpectus. The name is derived from the location of Zhucheng, the Latinized-Greek ceratops, or "horned face", and the unexpected articulated nature of the holotype. The skeleton was found in the Wangshi Group, which is of Late Cretaceous age, and most fossils are only disarticulated bones of Shantungosaurus.

Austrocheirus is an extinct genus of theropod dinosaur that lived during the Late Cretaceous period. It was named and described by Martin Ezcurra, Federico Agnolin and Fernando Novas in 2010. It contains the type species Austrocheirus isasii. The generic name means "southern hand". The specific epithet honours discoverer and preparator Marcelo Pablo Isasi.

Ojoceratops ( meaning "Ojo Alamo horned face") is a genus of ceratopsian dinosaur which lived in what is now New Mexico, United States. Ojoceratops fossils have been recovered from strata of the Ojo Alamo Formation (Naashoibito Member), dating to the late Cretaceous period (late Maastrichtian age, 66 million years ago). The type species is Ojoceratops fowleri.

Iguanacolossus (meaning "iguana colossus" or "colossal iguana") is a genus of iguanodontian ornithopod dinosaur that lived in North America during the Early Cretaceous period. It is known from UMNH VP 20205, the associated holotype with a large partial skeleton of a single individual.

Duriavenator is a genus of theropod dinosaur that lived in what is now England during the Middle Jurassic, about 168 million years ago. In 1882, upper and lower jaw bones of a dinosaur were collected near Sherborne in Dorset, and Richard Owen considered the fossils to belong to the species Megalosaurus bucklandii, the first named non-bird dinosaur. By 1964, the specimen was recognised as belonging to a different species, and in 1974 it was described as a new species of Megalosaurus, M. hesperis; the specific name means 'the West' or 'western'. Later researchers questioned whether the species b

Jingshanosaurus (meaning "Jingshan lizard") is a genus of sauropodomorph dinosaurs from the early Jurassic period (201.4 to 196.5 million years ago, Hettangian age) of China. The type and only species is Jingshanosaurus xinwaensis. Its maximum weight was around with an adult femur length of . The genus grew up to long.

Leshansaurus is a genus of theropod dinosaur from the Late Jurassic Shaximiao Formation of what is now China. It was described in 2009 by a team of Chinese paleontologists. The type species is Leshansaurus qianweiensis. Fossils of Leshansaurus were discovered in strata from the Shangshaximiao Formation, a formation rich in dinosaur fossils. Li et al. referred this taxon to Sinraptoridae – a group of carnosaurian theropods, but it may belong to Megalosauridae instead.

Rhoetosaurus (meaning "Rhoetus lizard", after a titan in Greek mythology) is a genus of sauropod dinosaur from the Late Jurassic (Oxfordian) Walloon Coal Measures of what is now eastern Australia. Rhoetosaurus is estimated to have been about long, weighing about . Subsequent authors have sometimes misspelled the name: Rhaetosaurus (de Lapparent & Laverat, 1955); Rheteosaurus (Yadagiri, Prasad & Satsangi, 1979).

Gondwanatitan (meaning "giant from Gondwana") was a titanosaurian sauropod dinosaur. Gondwanatitan was found in Brazil, at the time part of the southern supercontinent Gondwana, in the late Cretaceous Period (70 mya). Like some other sauropods, Gondwanatitan was tall and ate tough shoots and leaves from the tops of trees. Its closest relative was Aeolosaurus. The type species is Gondwanatitan faustoi, formally described by Kellner and de Azevedo in 1999.

Antetonitrus is a genus of sauropodiform dinosaur found in the Early Jurassic Elliot Formation of South Africa. The only species is Antetonitrus ingenipes. Sometimes considered a basal sauropod, it is crucial for the understanding of the origin and early evolution of this group. It was a quadrupedal herbivore, like its later relatives, but shows primitive adaptations to use the forelimbs for grasping, instead of purely for weight support.

Paronychodon (meaning "beside claw tooth") is an extinct theropod dinosaur genus. It is a tooth taxon, often considered dubious because of the fragmentary nature of the fossils, which include "buckets" of teeth from many disparate times and places but no other remains, and should be considered a form taxon.

Liaoningosaurus (meaning "Liaoning lizard") is an unusual genus of basal ankylosaurid dinosaur from the Liaoning Province, China that lived during the Early Cretaceous (late Barremian to early Aptian stages, ~125.4 to 118.9 Ma) in what is now the Yixian and Jiufotang Formation. The type and only species, Liaoningosaurus paradoxus, is known from more than 20 specimens, represented by juvenile individuals. It was named in 2001 by Xu, Wang and You.

Xixianykus is a genus of alvarezsaurid theropod dinosaur known from a slab of rock which contains a partial postcranial skeleton unearthed in the Late Cretaceous (Coniacian-Santonian) Majiacun Formation of the Xixia Basin in Henan, China.

Wendiceratops is a genus of herbivorous centrosaurine ceratopsian dinosaur from the Late Cretaceous of Canada.

Aepyornithomimus (meaning "Aepyornis mimic") is a genus of ornithomimid theropod dinosaur from the Late Cretaceous Djadochta Formation of Mongolia. It lived in the Campanian, around 75 million years ago, when the area is thought to have been a desert. The type and only species is A. tugrikinensis.

Zby is an extinct genus of turiasaurian sauropod dinosaur known from the Late Jurassic, particularly late Kimmeridgian stage of the Lourinhã Formation, in central west Portugal. It contains a single species, Zby atlanticus. It is named after , who studied the geology and paleontology of Portugal.

Gasparinisaura (meaning "Gasparini's lizard") is a genus of herbivorous ornithopod dinosaur from the Late Cretaceous. The first fossils of Gasparinisaura were found in 1992 near Cinco Saltos in Río Negro Province, Argentina. The type species, Gasparinisaura cincosaltensis, was named and described in 1996 by Rodolfo Coria and Leonardo Salgado. The generic name honors Argentine palaeontologist Zulma Brandoni de Gasparini. The specific name refers to Cinco Saltos.

Datousaurus (meaning "chieftain lizard" or "big-head lizard"; originally named using the Malay datu, after its Chinese nickname qiulong - literally "chieftain dragon" - but also a pun on its big head; da tou means "big head" in Chinese) is a sauropod dinosaur from the Middle Jurassic Lower Shaximiao Formation in Sichuan province, China. It shared the local Middle Jurassic landscape with other sauropods such as Shunosaurus, Omeisaurus, and Protognathosaurus, the neornithischian Xiaosaurus, and the early stegosaur Huayangosaurus as well as the carnivorous Gasosaurus.

Ilokelesia is an extinct genus of abelisaurid theropod dinosaurs, preserved in the layers of the earliest Late Cretaceous of the Huincul Formation (Neuquén Group) in Neuquén Province, Argentina. The only known specimen, consisting of fragmentary elements of the skull and skeleton, was described by Rodolfo Coria and Leonardo Salgado in late 1998.

Dromaeosauroides is a genus of dromaeosaurid theropod dinosaur from the Early Cretaceous of what is now Denmark and possibly also England. It was discovered in the Jydegaard Formation in the Robbedale valley, on the island of Bornholm in the Baltic Sea. This formation ranges from the Berriasian to the Valanginian ages. This is the only likely place for dinosaur remains to be discovered on Danish territory, since the Mesozoic deposits exposed in the rest of the country are marine. Dromaeosauroides is the first known dinosaur from Denmark, and the only one which has been scientifically named. It

Arstanosaurus (meaning "Arstan lizard" after the Arstan well) is a genus of hadrosauroid dinosaur from the Late Cretaceous-aged (Santonian-Campanian) Bostobe Formation of Kazakhstan. It has had a confusing history, being considered a hadrosaurid, a ceratopsid, or both at the same time (chimeric).

Beishanlong is a genus of giant ornithomimosaurian theropod dinosaur from the Early Cretaceous of China. It is the second-largest ornithomimosaur discovered, only surpassed by the related Deinocheirus.

Hulsanpes (meaning "Khulsan foot") is a genus of halszkaraptorine theropod dinosaurs that lived during the Late Cretaceous in what is now the Barun Goyot Formation of Mongolia, about 75-72 million years ago. The remains were found in 1970 and formally described in 1982 by Halszka Osmólska, who noted that the genus is represented by an immature individual. Hulsanpes represents the first record of the basal dromaeosaurid subfamily Halszkaraptorinae.

Bellusaurus (meaning "Beautiful lizard", from Vulgar Latin bellus 'beautiful' (masculine form) and Ancient Greek sauros 'lizard') was a sauropod dinosaur from the Late Jurassic (Oxfordian) known from juvenile specimens that would have measured about long. Its fossils were found in Shishugou Formation rocks in the northeastern Junggar Basin in China.

Auroraceratops, meaning "dawn horned face", is a genus of bipedal basal neoceratopsian dinosaur, from the Early Cretaceous (Aptian age) of north central China. The etymology of the generic name refers to its status as an early ceratopsian and also to Dawn Dodson, wife of Peter Dodson, one of the palaeontologists who described it.

Lycorhinus is a genus of heterodontosaurid ornithischian dinosaur from the Early Jurassic (Hettangian to Sinemurian ages) strata of the Elliot Formation located in the Cape Province, South Africa.

Barilium is a genus of iguanodontian dinosaur which was first described as a species of Iguanodon (I. dawsoni) by Richard Lydekker in 1888, the specific epithet honouring the discoverer Charles Dawson, who collected the holotype during the 1880s. thumb|upright|left|Middle dorsal vertebra In 2010 it was reclassified as a separate genus by David Norman. The generic name Barilium is derived from Greek barys, "heavy", and Latin ilium. Later in 2010, Kenneth Carpenter and Yusuke Ishida independently assigned it to the new genus Torilion, which is thus a junior objective synonym of Barilium. It is

Mendozasaurus is a genus of titanosaurian sauropod dinosaur. It was a member of Titanosauria, which were massive sauropods that were common on the southern landmasses during the Cretaceous. It is represented by several partial skeletons from a single locality within the Coniacian (lower Upper Cretaceous) Sierra Barrosa Formation in the south of Mendoza Province, northern Neuquén Basin, Argentina. The type species, Mendozasaurus neguyelap, was described by Argentine paleontologist Bernardo Javier González Riga in 2003. Mendozasaurus is the first dinosaur named from Mendoza Province, Argentina,

Sinornithomimus is a genus of ornithomimid dinosaur that lived in the Late Cretaceous Ulansuhai Formation of Alshanzuo Banner, Inner Mongolia, northern China. The first remains were found in 1997 and described six years later in 2003 as the new genus and species Sinornithomimus dongi.

Agnosphitys (; "unknown begetter"; sometimes mistakenly called Agnostiphys or Agnosphytis) is a genus of dinosauriform that lived during the Late Triassic. It contains only one species, the type species A. cromhallensis. Its remains include an ilium, maxilla, astragalus and humerus, which date variously from the Norian and Rhaetian stages of the Late Triassic, or possibly as late as the Hettangian stage of the Early Jurassic. The fissure fill at Avon, of which Agnosphitys was probably recovered from, was a sinkhole formed by the dissolution of Lower Carboniferous limestones.

Anoplosaurus (meaning "unarmored or unarmed lizard") is an extinct genus of herbivorous nodosaurid dinosaur from the Lower Cretaceous (late Albian age) Cambridge Greensand of Cambridgeshire, England. It has in the past been classified with either the armored dinosaurs or the ornithopods, but current thought has been in agreement with the "armored dinosaur" interpretation, placing it in the Ankylosauria.

Iliosuchus (meaning "crocodile-hipped") is a genus of theropod dinosaur known from Bathonian–age (168.3 – 166.1 mya) rocks of England. It was perhaps long.

Magnosaurus (meaning 'large lizard') was a genus of theropod dinosaur from the Middle Jurassic of England. It is based on fragmentary remains and has often been confused with or included in Megalosaurus.

Kotasaurus ( ; meaning "Kota Formation lizard") is a genus of sauropod dinosaur from the Early Jurassic period (Sinemurian–Pliensbachian). The only known species is Kotasaurus yamanpalliensis. It was discovered in the Kota Formation of Telangana, India and shared its habitat with the related Barapasaurus. So far the remains of at least 12 individuals are known. The greater part of the skeleton is known, but the skull is missing, with the exception of two teeth. Like some sauropods, it had a tail club that would have been used for intraspecific combat or interspecific defense.

Nuthetes is a genus of coelurosaurian theropod dinosaur, either a dromaeosaurid or tyrannosauroid, known only from fossil teeth and jaw fragments found in rocks of the middle Berriasian age (Early Cretaceous) in the Cherty Freshwater Member of the Lulworth Formation in England and also the Angeac-Charente bonebed in France. If it was a dromaeosaurid, Nuthetes would have been a small predator.

Jakapil (meaning "shield bearer" in Puelchean) is a genus of basal thyreophoran dinosaur from the Late Cretaceous (Cenomanian-aged) Candeleros Formation of Argentina. The type species is Jakapil kaniukura.

Rinconsaurus is a genus of titanosaur sauropod dinosaur from the Late Cretaceous in what is now Argentina. The type species, Rinconsaurus caudamirus, was described by Calvo and Riga in 2003, and is based on three partial skeletons.

Acristavus (meaning "non-crested grandfather") is a genus of saurolophine dinosaur. Fossils have been found from the Campanian Two Medicine Formation in Montana and Wahweap Formation in Utah, United States. The type species A. gagslarsoni was named in 2011. Unlike nearly all hadrosaurids except Edmontosaurus, Acristavus lacked ornamentation on its skull. The discovery of Acristavus is paleontologically significant because it supports the position that the ancestor of all hadrosaurids did not possess cranial ornamentation, and that ornamentation was an adaptation that later arose interdependent

Suzhousaurus (meaning "Suzhou lizard") is an extinct genus of large therizinosaurid dinosaurs from the Early Cretaceous of China. The genus is known from two specimens discovered in the Xiagou and Zhonggou Formations, both part of the Xinminbao Group. These findings were made during fieldwork in 1999 and 2004.

Maip is a genus of large megaraptorid theropod dinosaur from the Late Cretaceous (Maastrichtian) Chorrillo Formation of Santa Cruz, Argentina. The genus contains a single species, M. macrothorax, known from an incomplete, disarticulated skeleton. Maip may represent the largest megaraptorid known from South America, and possibly the world.

Mymoorapelta (Meaning "Shield from the Mygatt-Moore Quarry" after a combination of the names of the discoverers of the Mygatt-Moore Quarry that fossils were originally collected from, and the Greek word πέλτα, meaning "shield") is a nodosaurid ankylosaur from the Late Jurassic (Kimmeridgian-Tithonian, around 155 to 150 million years ago) Morrison Formation (Brushy Basin Member) of western Colorado and central Utah, USA. The animal is known from a single species, Mymoorapelta maysi, and few specimens are known. The most complete specimen is the holotype individual from the Mygatt-Moore Quarry,

Bradycneme (meaning "ponderous leg") is a genus of theropod dinosaur from the Upper Cretaceous-aged (Maastrichtian) Sânpetru Formation of the Hațeg Basin, Transylvania, Romania. The type species is Bradycneme draculae, known only from a partial right lower leg (specimen BMNH A1588), which its original describers believed it came from a giant owl.

Nomingia is a genus of oviraptorosaurian theropod dinosaur known from the Late Cretaceous Bugin Tsav Beds of Mongolia.
