Dinosaur genera

Fukuititan (meaning "giant from Fukui prefecture") is a genus of sauropod dinosaur that lived during the Early Cretaceous (either Barremian or Aptian age) in the Kitadani Formation in what is now Japan. The genus contains a single species, Fukuititan nipponensis. The discovery of Fukuititan shed light on Japanese titanosauriforms, which are generally very poorly-known.

Hanssuesia is a genus of pachycephalosaurid dinosaurs from the late Cretaceous period. It lived in what is now Alberta and Montana, and contains the single species Hanssuesia sternbergi. thumb|left|Life restoration Hanssuesia is based on a skull dome originally named Troodon sternbergi by Barnum Brown and Erich Maren Schlaikjer in 1943. The specific name honoured Charles Mortram Sternberg who found the dome in 1928 near Steveville in south Alberta. In 1945, it was transferred to Stegoceras by C.M. Sternberg himself, as a Stegoceras sternbergi.

Sanjuansaurus ("San Juan Province lizard") is a genus of herrerasaurid dinosaur from the Late Triassic (Carnian) Ischigualasto Formation of the Ischigualasto-Villa Unión Basin in northwestern Argentina.

Ferganasaurus (meaning "Fergana Valley lizard") is a genus of sauropod dinosaur that lived in the Balabansai Formation of Kyrgyzstan, which dates to the Callovian stage of the Middle Jurassic. It was formally described in 2003 by Alifanov and Averianov as the type species Ferganasaurus verzilini. It is believed to be similar to Rhoetosaurus.

Zhongyuansaurus (meaning "Zhongyuan lizard") is an extinct genus of ankylosaurid dinosaurs known from the Early Cretaceous Haoling Formation of what is now Henan Province, China. The genus contains two species, Z. luoyangensis, named in 2007, and Z. junchangi, named in 2025, both known from a single partial skeleton. Zhongyuansaurus is similar to Gobisaurus, prompting some researchers to regard the genera as synonymous.

Stenonychosaurus (meaning "narrow claw lizard") is a disputed genus of troodontid dinosaur from the Late Cretaceous Dinosaur Park Formation of Alberta, Canada, as well as possibly the Two Medicine Formation. The type and only species, S. inequalis, was named by Charles Mortram Sternberg in 1932, based on a foot, fragments of a hand, and some caudal vertebrae from the Late Cretaceous of Alberta. S. inequalis was reassigned in 1987 by Phil Currie to the genus Troodon, which was reverted by the recognition of Stenonychosaurus as a separate genus from the possibly dubious Troodon in 2017 by Evans

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.

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.

Silvisaurus, from the Latin silva "woodland" and Greek sauros "lizard", is a nodosaurid ankylosaur from the Early to Late Cretaceous period. It is the only known dinosaur species named from terrestrial deposits in Kansas and was designated the official state land fossil in 2023.

Camarillasaurus (meaning "Camarillas lizard") is an extinct genus of spinosaurid theropod dinosaurs from the Early Cretaceous period (Barremian) of Camarillas, Teruel Province, in what is now northeastern Spain. Described in 2014, it was originally identified as a ceratosaurian theropod, but later studies suggested affinities to the Spinosauridae. Camarillasaurus is one of several spinosaurid taxa known from the Iberian peninsula, the others being Iberospinus, Protathlitis, Baryonyx, Riojavenatrix, and Vallibonavenatrix.

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 .

Walgettosuchus (meaning "Walgett crocodile") is a dubious or possibly invalid genus of extinct tetanuran theropod dinosaur that lived in Australia during the Late Cretaceous (Cenomanian). It is known from a single caudal vertebra.

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.

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.

Amtosaurus () is a genus of ornithischian dinosaur based on a fragmentary skull collected from the Late Cretaceous (Cenomanian to Turonian) Bayanshiree Formation of Mongolia and originally believed to represent an ankylosaurid. Hadrosaurid affinities have also been suggested. However, according to Parish and Barrett, this specimen is too fragmentary to be reliably classified beyond an indeterminate ornithischian. A second species assigned to the genus, A. archibaldi, has become the basis of a valid ankylosaurid taxon, Bissektipelta.

Panamericansaurus (meaning "Pan American Energy lizard") is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Period of Argentina. The holotype is very similar to known fossil material of Aeolosaurus, which Panamericansaurus is thought to be closely related to.

Dongyangosaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous. The only species is Dongyangosaurus sinensis, from which only a single fragmentary skeleton is known, coming from the Zhejiang province of eastern China. It was described and named by Lü Junchang and colleagues. Like other sauropods, Dongyangosaurus would have been a large quadrupedal herbivore.

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.

Vorona berivotrensis ( ; Malagasy for "bird", berivotrensis, "from Berivotra") is a monotypic genus of prehistoric birds. It was described from fossils found in a Maevarano Formation quarry near the village of Berivotra, Mahajanga Province, Madagascar. The age of the fossilised specimen is Late Cretaceous, probably Maastrichtian (72.1-66.0 mya). V. berivotrensis is known from scattered remains, possibly from a single individual (UA 8651 and FMNH PA715).

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.

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.

Talenkauen is a genus of basal iguanodont dinosaur from the Campanian or Maastrichtian age of the Late Cretaceous Cerro Fortaleza Formation, formerly known as the Pari Aike Formation of Patagonian Lake Viedma, in the Austral Basin of Santa Cruz, Argentina.

Holtz gave a length of 25 meters (82 ft). left|thumb|Size comparison thumb|Life restoration with a human for scale

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.

thumb|left|Size compared to a human; anatomical details are speculative Ligabueino (meaning "Ligabue's little one") is a genus of abelisauroid theropod dinosaur named after its discoverer, Italian doctor Giancarlo Ligabue. It is known only from an extremely fragmentary specimen, measuring 79 cm (2.6 ft) long, found in the La Amarga Formation. In spite of initial reports that it was an adult, the unfused vertebrae indicate that the specimen was a juvenile. It was a theropod and lived during the Early Cretaceous Period (Barremian to early Aptian), in what is now Patagonia. Contrary to

Kaatedocus is a genus of flagellicaudatan sauropod known from the middle Late Jurassic (Kimmeridgian stage) of northern Wyoming, United States.

It is known from a single, incomplete postcranial skeleton consisting of a partial hindlimb, ischium, and two vertebrae. These remains were unearthed by Argentine paleontologist José Bonaparte in 1983 during an expedition by the Museo Argentino de Ciencias Naturales and later described as a new genus and species, Amargatitanis macni by Sebastián Apesteguía. The g

Lokiceratops (meaning "Loki horned face") is an extinct genus of centrosaurine ceratopsian dinosaurs from the Late Cretaceous (Campanian) Judith River Formation of Montana, United States. The genus contains a single species, L. rangiformis, known from most of the skull and a partial skeleton. Four other ceratopsians are known from the same stratigraphic interval as Lokiceratops—more than in any other locality—suggesting that this clade was very diverse during the Late Cretaceous of northern Laramidia.

Betasuchus is a genus of probable abelisaurid theropod dinosaur which lived during the Late Cretaceous Period. Betasuchus is, besides Orthomerus and birds such as Enantiornithines, the only dinosaur genus named from remains found in the Netherlands and the only non-avian theropod found in the Maastrichtian Beds.

Baurutitan is a genus of sauropod dinosaur that lived during the Late Cretaceous in what is now Brazil. The type species, Baurutitan britoi, was described in 2005 by Kellner and colleagues, although the fossil remains had already been discovered in 1957. Baurutitan is classified as a lithostrotian titanosaur, and is distinguished from related genera based on its distinctive caudal vertebrae. This South American dinosaur was found in the Serra da Galga Formation near Uberaba, in the Brazilian state of Minas Gerais.

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.

Efraasia (pronounced "E-FRAHS-ee-A") is a genus of basal sauropodomorph dinosaur. It was a herbivore which lived during the middle Norian stage of the Late Triassic, around 210 million years ago, in what is now Germany. It was named in 1973 after Eberhard Fraas, who during the early twentieth century collected what were the original type specimens. The specimens were at first assigned to three already existing genera and so became divided among three separate species: Teratosaurus minor, Sellosaurus fraasi and Paleosaurus diagnosticus. In 2003, these were combined into a single valid spec
