Dinosaur genera

Talarurus ( ; meaning "basket tail" or "wicker tail") is a genus of ankylosaurid dinosaur that lived in Asia during the Late Cretaceous period, about 96 million to 89 million years ago. The first remains of Talarurus were discovered in 1948 and later described by the Russian paleontologist Evgeny Maleev with the type species T. plicatospineus. It is known from multiple yet sparse specimens, making it one of the most well known ankylosaurines, along with Pinacosaurus. Elements from the specimens consists of various bones from the body; five skulls have been discovered and assigned to the genus,

thumb|Astrodon holotype tooth Astrodon is a genus of large herbivorous sauropod dinosaur, measuring in length, in height and in body mass. It lived in what is now the eastern United States during the Early Cretaceous period, and fossils have been found in the Arundel Formation, which has been dated through palynomorphs to the Albian about 112 to 110 million years ago.

Argyrosaurus ( ) is a genus of titanosaurian sauropod dinosaur that lived about 70 million years ago, during the Late Cretaceous Period of what is now Argentina.

Hesperosaurus (from Ancient Greek ἕσπερος (hésperos), meaning "western", and σαῦρος (saûros), meaning "lizard") is a herbivorous stegosaurian dinosaur from the Kimmeridgian age of the Jurassic period, approximately 156 million years ago.

Achillesaurus is a genus of alvarezsaurid theropod dinosaur from the Santonian-aged (Late Cretaceous) Bajo de la Carpa Formation of Rio Negro, Argentina. It contains one species, Achillesaurus manazzonei.

Ampelosaurus ( ; meaning "vine lizard") is a titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now France. Its type species is A. atacis, named by Le Loeuff in 1995. Its remains were found in a level dating from 71.5 million years ago representing the early Maastrichtian.

Jobaria is a genus of sauropod dinosaur that lived in what is now Niger during the middle Jurassic Period, between 164 and 161 million years ago. Jobaria is currently the only known valid sauropod from the Tiouraren, where it was discovered in 1997.

Prosaurolophus (; meaning "before Saurolophus", in comparison to the later dinosaur with a similar head crest) is a genus of hadrosaurid (or duck-billed) dinosaur from the Late Cretaceous of North America. It is known from the remains of at least 25 individuals, including skulls and skeletons, but this remains obscure. Its fossils have been found in the late Campanian-aged Dinosaur Park Formation in Alberta, and the roughly contemporaneous Two Medicine Formation in Montana, dating to around 75.7 to 74.1 million years ago. Its most recognizable feature is a small solid crest formed by the nasal

Atlasaurus is a genus of sauropod dinosaurs from Middle Jurassic (Bathonian to Callovian stages) beds in North Africa.

Archaeornithomimus (meaning "ancient bird mimic") is a genus of ornithomimosaurian theropod dinosaur that lived during the Late Cretaceous period (around 96 million years ago) in the Iren Dabasu Formation of Inner Mongolia, China.

Microceratus (meaning "small-horned") is a genus of small ceratopsian dinosaur that lived in the Cretaceous period of Mongolia. It walked on two legs, had short front arms, a characteristic ceratopsian frill and beak-like mouth, and was around long. It was one of the most primitive ceratopsians, or horned dinosaurs, along with Psittacosaurus, which was also discovered in Mongolia.

Avaceratops is a genus of small herbivorous ceratopsian dinosaurs which lived during the late Campanian in what are now the Northwest United States. Most fossils come from the Judith River Formation.

Wintonotitan (meaning "Winton titan") is a genus of titanosauriform dinosaur from the Cenomanian-aged (Late Cretaceous) Winton Formation of Australia. It is known from partial postcranial remains.

Rhabdodon (meaning "fluted tooth") is a genus of ornithopod dinosaur that lived in Europe approximately 72-69 million years ago in the Late Cretaceous. The genus contains a single species, R. priscus. It is similar in build to a very robust "hypsilophodont" (non-iguanodont ornithopod), though all modern phylogenetic analyses find this to be an unnatural grouping, and Rhabdodon to be a basal member of Iguanodontia. It was large amongst its relatives, measuring long and weighing , with some specimens possibly reaching up to long.

Opisthocoelicaudia is a genus of sauropod dinosaur of the Late Cretaceous Period discovered in the Gobi Desert of Mongolia. The type species is Opisthocoelicaudia skarzynskii. A well-preserved skeleton lacking only the head and neck was unearthed in 1965 by Polish and Mongolian scientists, making Opisthocoelicaudia one of the best known sauropods from the Late Cretaceous. Tooth marks on this skeleton indicate that large carnivorous dinosaurs had fed on the carcass and possibly had carried away the now-missing parts. To date, only two additional, much less complete specimens are known, includin

Segisaurus (meaning "Tsegi Canyon lizard") is a genus of small coelophysid theropod dinosaur, that measured approximately 1 metre (3.3 feet) in length. The only known specimen was discovered in early Jurassic strata in Tsegi Canyon, Arizona, for which it was named. Segisaurus is the only dinosaur to have ever been excavated from the area.

Kryptops (meaning "covered face") is an extinct genus of possibly chimeric abelisaurid theropod dinosaurs from the Early Cretaceous of Niger. It is known from a partial maxilla (upper jaw bone) found at the Gadoufaoua locality in the western Ténéré Desert, in rocks of the Aptian–Albian-age Elrhaz Formation. The fossils were collected in 2000 by a University of Chicago expedition to Niger led by American paleontologist Paul Sereno. They were then described in 2008 by Sereno and Steve Brusatte. The genus contains a single species, Kryptops palaios. Sereno and Brusatte referred several postcrania

Alwalkeria (; "for Alick Walker") is a historically problematic extinct genus of avemetatarsalian known from the Late Triassic Lower Maleri Formation of India. The genus contains a single species, Alwalkeria maleriensis. It was initially described in 1987 under the genus name , based on a partial skull, several vertebrae, and fragmentary hindlimb bones. As this name is preoccupied, the new genus Alwalkeria was proposed to replace it. Early research interpreted the material belonging to a 'podokesaurid' (coelophysoid) theropod, herrerasaur, or Eoraptor-like basal eusaurischian dinosaur. Subsequ

Liliensternus is an extinct genus of basal neotheropod dinosaur that lived approximately 210 million years ago during the latter part of the Triassic Period in what is now Germany. Liliensternus was a bipedal, ground-dwelling carnivore, that could grow up to long; however, this size estimate is based on specimens now believed to be subadults, and possible fragmentary remains indicate an adult length of 7 to 9 meters. It is the best represented Triassic theropod from Europe and one of the largest known.

Andesaurus ( ; "Andes lizard") is a genus of basal titanosaurian sauropod dinosaur which existed during the middle of the Cretaceous Period in South America. Like most sauropods, it would have had a small head on the end of a long neck and an equally long tail.

Halszkaraptor (; meaning "Halszka's seizer") is a genus of waterfowl-like dromaeosaurid dinosaurs from Mongolia that lived during the Late Cretaceous period. It contains only one known species, Halszkaraptor escuilliei.

Bruhathkayosaurus (; meaning "huge-bodied lizard") is a genus of sauropod dinosaur found in the Kallamedu Formation of India. The fragmentary remains were originally described as a theropod, but it was later determined to be a titanosaur sauropod. Length estimates by researchers exceed those of the titanosaur Argentinosaurus, as longer than and weighing over 80 tonnes. A 2023 estimate placed Bruhathkayosaurus as potentially weighing , with paleontologist Michael Benton, estimating a length of . If the upper estimates of the 2023 records are accurate, Bruhathkayosaurus may have rivaled the blue

Jinfengopteryx (from , 'golden phoenix', the queen of birds in Chinese folklore, and , meaning 'feather') is a genus of maniraptoran dinosaur. It was found in the Qiaotou Member of the Huajiying Formation of Hebei Province, China, and is therefore of uncertain age. The Qiaotou Member may correlate with the more well-known Early Cretaceous Yixian Formation, and so probably dates to around 122 Ma (122 million years) ago.

Melanorosaurus (meaning "Black Mountain Lizard", from the Greek melas/, "black", oros/, "mountain" + /, "lizard") is a genus of basal sauropodomorph dinosaur that lived during the Late Triassic period. An omnivore from South Africa, it had a large body and sturdy limbs, suggesting it moved quadrupedally. Its limb bones were massive and heavy like the limb bones of true sauropods.

Isisaurus (named after the Indian Statistical Institute) is a genus of titanosaurian dinosaur from the Late Cretaceous Lameta Formation of India and Pab Formation of Pakistan. The genus contains a single species, Isisaurus colberti.

Borealopelta (meaning 'northern shield') is an extinct genus of herbivorous nodosaurid ankylosaur from the Lower Cretaceous of what is today Alberta, Canada. It contains a single species, B. markmitchelli, named in 2017 by Caleb Brown and colleagues from a well-preserved specimen known as the Suncor nodosaur. Discovered at an oil sands mine north of Fort McMurray, Alberta, the specimen is remarkable for being among the best-preserved dinosaur fossils of its size ever found. It preserved not only the armor (osteoderms) in their life positions, but also remains of their keratin sheaths, overlyin

Parksosaurus (meaning "William Parks's lizard") is a genus of neornithischian dinosaur from the early Maastrichtian-aged (Upper Cretaceous) Horseshoe Canyon Formation of Alberta, Canada. It is based on most of a partially articulated skeleton and partial skull, showing it to have been a small, bipedal, herbivorous dinosaur. It is one of the few described non-hadrosaurid ornithopods from the end of the Cretaceous in North America, existing around 70 million years ago.

Yamaceratops is a genus of primitive ceratopsian that lived during the Late Cretaceous in what is now Mongolia. The genus contains a single species, Y. dorngobiensis. It was a relatively small dinosaur, with an estimated length of and weighing around .

Eotriceratops (meaning "dawn three-horned face") is a genus of herbivorous ceratopsian dinosaurs which lived in the area of North America during the late Cretaceous period. The only named species is Eotriceratops xerinsularis.

Scansoriopteryx ("climbing wing") is a genus of maniraptoran dinosaur. Described from only a single juvenile fossil specimen found in Liaoning, China, Scansoriopteryx is a sparrow-sized animal that shows adaptations in the foot indicating an arboreal (tree-dwelling) lifestyle. It possessed an unusual, elongated third finger which may have supported a membranous wing, much like the related Yi qi. The type specimen of Scansoriopteryx also contains the fossilized impression of feathers.

Arrhinoceratops (meaning "no nose-horn face", derived from the Ancient Greek "a-/α-" "no", rhis/ῥίς "nose" "keras/κέρας" "horn", "-ops/ὤψ" "face") is a genus of herbivorous ceratopsian dinosaur. The name was coined as its original describer concluded it was special because the nose-horn was not a separate bone, however further analysis revealed this was based on a misunderstanding. It lived during the latest Campanian/earliest Maastrichtian stage of the Late Cretaceous, predating its famous relative Triceratops by a few million years, although it was contemporary with Anchiceratops. Its remain

Aardonyx (Afrikaans aard, "earth" + Greek , "nail, claw") is a genus of basal sauropodomorph dinosaur. It is known from the type species Aardonyx celestae found from the Early Jurassic Elliot Formation of South Africa. A. celestae was named after Celeste Yates, who prepared much of the first known fossil material of the species. It has arm features that are intermediate between basal sauropodomorphs and more derived sauropods.

Aragosaurus (meaning "Aragon lizard") was a genus of sauropod dinosaur from the Early Cretaceous period of Galve, province of Teruel, in the autonomous territory of Aragón, Spain. It was deposited in the Villar del Arzobispo Formation.

Yinlong (, meaning "hidden dragon") is a genus of basal ceratopsian dinosaur from the Late Jurassic Period of China. By far the earliest known ceratopsian, it was a small, primarily bipedal herbivore.

Patagotitan is a genus of titanosaurian sauropod dinosaur from the Early Cretaceous (Albian stage) Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from at least six young adult individuals, Patagotitan mayorum, which was first announced in 2014 and then named in 2017 by José Carballido and colleagues. Originally thought to be the largest known titanosaur and land animal overall, preliminary studies and press releases suggested that Patagotitan had an estimated length of and an estimated weight of . Later research revised the length es

Euhelopus is a genus of sauropod dinosaur that lived between 143 and 133 million years ago during the Berriasian and Valanginian ages of the Early Cretaceous in what is now Shandong Province in China. It was a large quadrupedal herbivore. Like sauropods such as brachiosaurids and titanosaurs, Euhelopus had longer forelimbs than hindlimbs. This discovery was paleontologically significant because it represented the first dinosaur scientifically investigated from China: seen in 1913, rediscovered in 1922, excavated in 1923, and studied by T'an during the same year. Unlike most sauropod specimens,

Bistahieversor (meaning "Bistahi destroyer"), also known as the "Bisti Beast", is a genus of basal eutyrannosaurian theropod dinosaur. The genus contains only a single known species, B. sealeyi, described in 2010, from the Late Cretaceous of New Mexico. The holotype and a juvenile were found in the Hunter Wash Member of the Kirtland Formation, while other specimens came from the underlying Fossil Forest member of the Fruitland Formation. This dates Bistahieversor approximately 75.5 to 74.5 million years ago during the Campanian age, found in sediments spanning a million years.

Haplocanthosaurus (meaning "simple spined lizard") is a genus of diplodocoid sauropod dinosaur. Two species, H. delfsi and H. priscus, are known from incomplete fossil skeletons. They lived during the Late Jurassic (Kimmeridgian stage), 155 to 152 million years ago in North America. The type species is H. priscus, named in 1903 John Bell Hatcher , and the referred species H. delfsi was discovered by a young college student named Edwin Delfs in Colorado, United States and described by Jack McIntosh and Michael Williams in 1988. Haplocanthosaurus specimens have been found in the lowermost layer

Protarchaeopteryx (meaning "before Archaeopteryx" although it is from the Cretaceous and Archaeopteryx is from the Jurassic) is a genus of turkey-sized feathered theropod dinosaur from China. Known from the Jianshangou bed of the Yixian Formation, it lived during the early Aptian age of the Early Cretaceous, approximately 124.6 million years ago. It was probably a herbivore or omnivore, although its hands were very similar to those of small carnivorous dinosaurs. It appears to be one of the most basal members of the Oviraptorosauria, closely related to Incisivosaurus, or a taxon slightly

Nasutoceratops is a genus of ceratopsid dinosaur that lived in North America during the Late Cretaceous period, about 76.0–75.5 million years ago. The first known specimens were discovered in Utah in the Kaiparowits Formation of the Grand Staircase–Escalante National Monument (GSENM) from 2006 onwards, including a subadult skull with both a partial postcranial skeleton and rare skin impressions, and two other partial skulls. In 2013, the subadult was made the holotype of the new genus and species Nasutoceratops titusi; the generic name means "large-nosed horned face", and the specific name hon

Incisivosaurus ("incisor lizard") is a genus of small, probably herbivorous theropod dinosaurs from the early Cretaceous Period of what is now the People's Republic of China. The first specimen to be described (by Xu et al. in 2002), IVPP V13326, is a skull that was collected from the lowermost levels (the fluvial Lujiatun beds) of the Yixian Formation (dating to the Barremian stage about 126 million years ago) in the Sihetun area, near Beipiao City, in western Liaoning Province. The most significant, and highly unusual, characteristic of this dinosaur is its apparent adaptation to an herbivor

thumb|Life reconstruction|left Wannanosaurus (meaning "Wannan lizard", named after the location where it was discovered) is a genus of basal pachycephalosaurian dinosaur from the Maastrichtian-aged (Upper Cretaceous) Xiaoyan Formation, about 70 million years ago, in what is now Anhui, China. The type species Wannanosaurus yansiensis was described by Hou Lian-Hai in 1977.

Titanoceratops (meaning "titanic horned face") is a controversial genus of chasmosaurine ceratopsian dinosaur that lived in the Late Cretaceous period (Campanian stage, about 75 million years ago) in what is now New Mexico. Titanoceratops was named for its large size, being one of the largest known horned dinosaurs and the type species was named T. ouranos, after Uranus (Ouranos), the father of the Greek titans. It was named in 2011 by Nicholas R. Longrich for a specimen previously referred to Pentaceratops. Longrich believed that unique features found in the skull reveal it to have been a clo

Haplocheirus (, from Ancient Greek ἁπλός (haplós), meaning "simple", and χείρ (kheír), meaning "hand") is an extinct genus of theropod dinosaur from the Middle Jurassic Shishugou Formation of Xinjiang in China. It is generally considered to be an alvarezsauroid, although some researchers have questioned this assignment. The genus contains a single species, H. sollers, which is known from a mostly complete skeleton including the skull.

Variraptor ( ; "Var thief") is a possibly dubious and potentially chimaeric genus of dromaeosaurid theropod dinosaur from the Late Cretaceous of France.

Indosuchus () is a genus of abelisaurid dinosaur from the Late Cretaceous Period (Maastrichtian, 70 to 66 million years ago) of what is now India. Like most theropods, Indosuchus was a bipedal carnivore. It was about long, weighed about , and had a crested skull, flattened on the top.

Aepisaurus (; derived from the Greek: , '''' - 'lofty/high' and , '''' - 'lizard', i.e. "lofty lizard") was a genus of sauropod dinosaur from the Albian-age Lower Cretaceous Grès vert of Département du Vaucluse, France, around 100.5 million years ago. It is an obscure genus from an unknown family, represented by a single humerus, now partly lost. Despite its lack of popularity, or perhaps because of it, it has been misspelled several ways in the scientific literature, with multiple dates given to the year of description as well.

Lexovisaurus is a genus of stegosaurian dinosaur known from limb bones and armor fragments from Middle to Late Jurassic-aged strata of Europe.

Bahariasaurus (meaning "Bahariya lizard") is an enigmatic genus of large theropod dinosaur. The genus contains a single species, Bahariasaurus ingens, which was found in North African rock layers dating to the Cenomanian age of the Late Cretaceous. The only fossils confidently assigned to Bahariasaurus were found in the Bahariya Formation of the Bahariya Oasis in Egypt by Ernst Stromer. This material was destroyed during a World War II bombing raid, with the same raid also destroying the holotypes of Spinosaurus, Aegyptosaurus, and other animals found in the Bahariya Formation.

Quaesitosaurus (meaning "extraordinary lizard") is a genus of nemegtosaurid sauropod containing only the type species, Q. orientalis, described in 1983. It lived from 72 to 71 million years ago during the Late Cretaceous epoch in the Barun Goyot Formation. With long, low and horse-like with frontally located peg-teeth, the skull of Quaesitosaurus is similar enough to the skull of Diplodocus and its kin to have prompted informed speculation that the missing body was built like those of diplodocids.

Ichthyovenator is a genus of spinosaurid dinosaur that lived in what is now Laos, sometime between 120 and 113 million years ago, during the Aptian stage of the Early Cretaceous period. It is known from fossils collected from the Grès supérieurs Formation of the Savannakhet Basin, the first of which were found in 2010, consisting of a partial skeleton without the skull or limbs. This specimen became the holotype of the new genus and species Ichthyovenator laosensis, and was described by palaeontologist Ronan Allain and colleagues in 2012. The generic name, meaning "fish hunter", refers to

Udanoceratops (meaning "Udan-Sayr horned face") is a genus of large leptoceratopsid dinosaur that lived during the Late Cretaceous period of Mongolia. The holotype specimen, the partial skeleton of an adult with its bones encapsulated in calcium carbonate, was discovered in the 1980s as part of the Joint Soviet-Mongolian Paleontological Expedition, and was subsequently transported to the Paleontological Institute of the Russian Academy of Sciences. In 1992, it was described by palaeontologist Sergei Kurzanov. The sole species of Udanoceratops, also the type species, is Udanoceratops tschizhovi

Guaibasaurus is an extinct genus of basal saurischian dinosaur known from the Late Triassic Caturrita Formation of Rio Grande do Sul, southern Brazil. Most analyses recover it as a sauropodomorph, although there are some suggestions that it was a theropod instead. In 2016 Gregory S. Paul estimated it at around 2 meters long (6.6 ft) and 10 kg (22 lbs), whereas in 2020 Molina-Pérez and Larramendi listed it at 3 meters (10 ft) and 35 kg (77 lbs).

Microvenator (meaning "small hunter") is a genus of oviraptorosaurian theropod dinosaur from the Early Cretaceous Cloverly Formation in what is now south central Montana. The holotype fossil is an incomplete skeleton, most likely a juvenile with a length of , and consequently, the adult size remains uncertain. Microvenator is primitive and may be the "sister taxon to all other oviraptorosaurs."

Bonitasaura is a genus of titanosaurian dinosaur hailing from uppermost layers of the Late Cretaceous (Santonian) Bajo de la Carpa Formation, Neuquén Group of the eastern Neuquén Basin, located in Río Negro Province, Northwestern Patagonia, Argentina. The remains, consisting of a partial sub-adult skeleton jumbled in a small area of fluvial sandstone, including a lower jaw with teeth, a partial vertebrae series, and limb bones, were described by Sebastian Apesteguía in 2004.

Sinosaurus (meaning "Chinese lizard") is an extinct genus of basal theropod dinosaur which lived during the Early Jurassic (Hettangian-Sinemurian). Fossils of the animal have been found in the Lufeng Formation, in the Yunnan Province of China. The type species, S. triassicus, was named by Chung Chieng Young in 1940. A second species, S. sinensis, was originally assigned to Dilophosaurus, but was later reassigned to Sinosaurus. Sinosaurus is morphologically similar to Dilophosaurus including the presence of a similarly shaped cranial crest, though its precise taxonomic position is uncertain, an

Amurosaurus (; "Amur lizard") is a genus of lambeosaurine hadrosaurid dinosaur found in Late Cretaceous (70 to 66 million years ago) deposits of what is now eastern Asia.

Chilantaisaurus (" lizard") is an extinct genus of large theropod dinosaur that lived in present-day China during the Late Cretaceous period. It was described by Chinese paleontologist Hu Show-Yung in 1964. The genus contains a single valid species, C. tashuikouensis, though several other species have been assigned to the genus. C. tashuikouensis is known from a single, incomplete postcranial skeleton, the holotype specimen. This specimen was found by a joint Sino-Soviet expedition to Inner Mongolia in rock layers coming from the Ulansuhai Formation. This indicates these fossils date to the Sa

Zephyrosaurus (meaning "westward wind lizard") is a genus of orodromine ornithischian dinosaur based on a partial skull and postcranial fragments discovered in the Early Cretaceous (Aptian-Albian) Cloverly Formation of Carbon County, Montana, USA. New remains are under description, and tracks from Maryland and Virginia, also in the US, have been attributed to animals similar to Zephyrosaurus.
