Tetanurae

Tetanurae (; meaning "stiff tails") is a clade that includes most theropod dinosaurs, including megalosauroids, allosauroids, and coelurosaurs (which includes tyrannosauroids, ornithomimosaurs, compsognathids and maniraptorans, the latter including living birds). Tetanurans are defined as all theropods more closely related to modern birds than to Ceratosaurus and contain the majority of predatory dinosaur diversity. Tetanurae likely diverged from its sister group, Ceratosauria, during the late Triassic. Tetanurae first appeared in the fossil record by the Early Jurassic about 190 mya and by th

Monolophosaurus ( ; meaning "single-crested lizard") is an extinct genus of tetanuran theropod dinosaur from the Middle Jurassic Shishugou Formation in what is now Xinjiang, China. It was named for the single crest on top of its skull. Monolophosaurus was a mid-sized theropod at about long and weighed .

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

Lourinhanosaurus (meaning "Lourinhã lizard") was a genus of carnivorous theropod dinosaur that lived during the Late Jurassic Period (Kimmeridgian/Tithonian) in Portugal. It is one of many large predators discovered at the Lourinhã Formation and probably competed with coeval Torvosaurus gurneyi, Allosaurus europaeus, and Ceratosaurus.

Zuolong (International Phonetic Alphabet|) is an extinct genus of tetanuran theropod from the Late Jurassic period of China. The type and only species is Z. salleei. The generic name of Zuolong is in honor of General Zuo Zōngtáng (also known as "General Tso") with the Chinese word "long" which means dragon. The specific epithet "salleei" is in honor of Hilmar Sallee, who funded the expedition which led to the specimen's discovery.

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

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.

Cruxicheiros (meaning "cross hand") is a genus of theropod dinosaur which lived in the Middle Jurassic of England. The type species is C. newmanorum, described by Roger Benson and Jonathan Radley in 2010.

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.

Szechuanosaurus ("Szechuan lizard") is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian-?Tithonian (Peng et al., 2005). Its type species is based on several undiagnostic teeth from the Kuangyuan Series. Additional possible specimens of Szechuanosaurus were also reported from the Kalaza Formation, also located in China.

Gualicho (named in reference to the gualichu) is an enigmatic genus of theropod dinosaurs. The type species is Gualicho shinyae. It lived in what is now northern Patagonia, on what was then a South American island continent split off from the supercontinent Gondwana. The fossils were found in the Huincul Formation, dating to the late Cenomanian-early Turonian age of the upper Cretaceous Period, around 91 million years ago.

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.

Dandakosaurus (meaning "Dandakaranya lizard") is a dubious genus of theropod dinosaur from the Kota Formation, Andhra Pradesh, India. It lived 183 to 175 million years ago from the latest Pliensbachian to the late Toarcian stages of the Early Jurassic. Little is known about the genus, and some paleontologists consider it to be a nomen dubium.

Embasaurus (meaning "Emba lizard") is a dubious genus of tetanuran theropod dinosaur from the Early Cretaceous period. It is known from two vertebrae found in the Neocomian Sands of Kazakhstan. As it is known only from fragmentary remains, Embasaurus is considered by some to be a possible nomen dubium. It was named after the Emba River, and it is believed to have lived during the Berriasian stage, around 140 million years ago. According to the Theropod Database, a personal website designed by Mickey Mortimer, further research may suggest that Embasaurus may be a basal tyrannosauroid. George Ol

Kayentavenator (meaning "Kayenta hunter") is a genus of small carnivorous tetanuran dinosaur that lived during the Early Jurassic Period. Fossils were recovered from the Kayenta Formation of northeastern Arizona, and were described in 2010.

Vectaerovenator (meaning "Isle of Wight air-filled hunter" due to the pneumaticity of the vertebrae) is a genus of tetanuran theropod from the Early Cretaceous period of what is now England (Lower Greensand Group; Ferruginous Sands). It contains one species, Vectaerovenator inopinatus; its holotype, consisting of the specimens IWCMS 2020.400, 2020.407, and 2019.84, comprises two anterior dorsal vertebrae, a cervical vertebra and a mid‐caudal vertebra from the late Aptian Ferruginous Sands of the Isle of Wight in southern England, discovered in 2019. Comparative anatomical analysis shows that t

Datanglong is an extinct genus of tetanuran theropod of uncertain taxonomic placement. It existed during Xinlong Formation, Early Cretaceous (Barremian-Albian), in what is now Guangxi China.

Pandoravenator (meaning "Pandora hunter", after the type locality, "Caja de Pandora", i.e. Pandora's box) is a genus of theropod dinosaur from the Late Jurassic (Oxfordian to Tithonian) of central Patagonia (Chubut Province). Fossils in the form of a fragmentally preserved postcranial skeleton of this dinosaur were discovered and scientifically described in 2017 by paleontologists Oliver Rauhut and Diego Pol as the type species P. fernandezorum.

Chienkosaurus ("lizard of Jiange County") is a dubious genus of carnivorous theropod dinosaur from the Late Jurassic Kuangyuan Series of China. It was probably related to Szechuanosaurus.
