Oxfordian dinosaurs

Sinraptor () is a genus of metriacanthosaurid theropod dinosaur from the Shishugou Formation China. Sinraptor and its close relatives were among the earliest members of the Jurassic carnosaurian radiation. Sinraptor still remains the best-known member of the family Metriacanthosauridae, with some older sources even using the name "Sinraptoridae" for the family.

Eustreptospondylus ( ;), from (Ancient Greek εὖ (eû), meaning "well", στρεπτός (streptós), meaning "twisted", and σπόνδυλος (spóndulos), meaning "vertebra"), is an extinct genus of megalosaurid theropod dinosaur, from the Callovian and Oxfordian stages of the Jurassic period (some time between 166 and 154 million years ago) in southern England, at a time when Europe was a series of scattered islands (due to tectonic movement at the time which raised the sea-bed and flooded the lowland).

Guanlong () is an extinct genus of proceratosaurid tyrannosauroid dinosaur from the Late Jurassic (Oxfordian) Shishugou Formation of China. It was first described in 2006 by Xu Xing and colleagues, who found it to represent a new taxon related to Tyrannosaurus. Two individuals are currently known, consisting of a partially complete adult and a nearly complete juvenile.

Shunosaurus () is a genus of sauropod dinosaur from Late Jurassic (Oxfordian) beds in Sichuan Province in China, from 161 to 157 Million years ago. The name derives from "Shu", an ancient name for the Sichuan province.

Metriacanthosaurus (meaning "moderately-spined lizard") is a genus of metriacanthosaurid dinosaur from the Oxford Clay Formation of England, dating to the Late Jurassic period, about 160 million years ago (lower Oxfordian). It is the only metriacanthosaurid currently named from outside of Asia.

Aurornis is an extinct genus of anchiornithid theropod dinosaurs from the Jurassic Period of China. The genus Aurornis contains a single known species, Aurornis xui (). Aurornis xui may be the most basal ("primitive") avialan dinosaur known to date, and it is one of the earliest avialans found to date. The fossil evidence for the animal pre-dates that of Archaeopteryx lithographica, often considered the earliest bird species, by about 10 million years.

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.

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.

Limusaurus is a genus of theropod dinosaur that lived in what is now China during the Late Jurassic, around 161 to 157 million years ago. The type and only species Limusaurus inextricabilis was described in 2009 from specimens found in the Upper Shishugou Formation in the Junggar Basin of China. The genus name consists of the Latin words for "mud" and "lizard", and the species name means "impossible to extricate", both referring to these specimens possibly dying after being mired. Limusaurus was a small, slender animal, about in length and in weight, which had a long neck and legs bu

Anchiornis is a genus of small, four-winged paravian dinosaurs, with only one known species, the type species Anchiornis huxleyi, named for its similarity to modern birds. The Latin name Anchiornis derives from a Greek word meaning "near bird", and huxleyi refers to Thomas Henry Huxley, a contemporary of Charles Darwin. Anchiornis fossils have been found only in the Tiaojishan Formation of Liaoning, China, in rocks dated to the Late Jurassic, about 160 million years ago. It is known from hundreds of specimens, and given the exquisite preservation of some of these fossils, it became the first M

Chialingosaurus (meaning "Chialing Lizard") is a genus of herbivorous stegosaurian dinosaur similar to Kentrosaurus from the Upper Shaximiao Formation, Late Jurassic beds in Sichuan Province in China. Its age makes it one of the oldest species of stegosaurs, living about 160 million years ago. Since it was an herbivore, scientists think that Chialingosaurus probably ate ferns and cycads, which were plentiful during the period when Chialingosaurus was alive.

Gigantspinosaurus () is a genus of stegosaurian dinosaur from the Late Jurassic (Oxfordian) Upper Shaximiao Formation of China. The type species is Gigantspinosaurus sichuanensis. It was a moderately sized member of the group, measuring up to in length.

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.

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.

Pedopenna () (meaning "foot feather") is a genus of small, feathered, maniraptoran dinosaur from the Daohugou Beds in China. It is possibly older than Archaeopteryx, though the age of the Daohugou Beds where it was found is debated. A majority of studies suggest that the beds probably date from between the late Middle Jurassic (168 million years ago) and early Late Jurassic Period (164-152 million years ago).

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).

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.

Aorun () (敖闰 pinyin Áo rùn) is a genus of carnivorous theropod dinosaur first discovered in 2006, with its scientific description published in 2013. It is generally considered one of the oldest known coelurosaurian dinosaurs and is estimated to have lived ~161.6 million years ago during the Late Jurassic Period, though some researchers consider it to be a carnosaurian instead.

Caihong () is a genus of small paravian theropod dinosaur from China that lived during the Late Jurassic period.

Ambopteryx (meaning "both wing") is a genus of scansoriopterygid dinosaur from the Oxfordian stage of the Late Jurassic of China. It is the second dinosaur to be found with both feathers and bat-like membranous wings. Yi, the first such dinosaur, was described in 2015 and is the sister taxon to Ambopteryx. The holotype specimen is thought to be a sub-adult or adult. The specimen is estimated to have had a body length of and a weight of . The genus includes one species, Ambopteryx longibrachium.

Streptospondylus, (Ancient Greek στρεπτός (streptós), meaning "twisted", and σπόνδυλος (spóndulos), meaning "vertebra",) is a genus of megalosaurid theropod dinosaur known from the Late Jurassic period of France, 161 million years ago. It was a medium-sized predator with an estimated length of 6 meters (19.5 ft) and a weight of 500 kg (1,100 lbs).

Daanosaurus (meaning "Da'an lizard" after Da'an district in Zigong, Sichuan) was a genus of sauropod dinosaur which lived during the Late Jurassic (Oxfordian - Tithonian stage, about 163 - 145 mya). It lived in what is now China (Sichuan Province), and was similar to Bellusaurus. Daanosaurus is known only from a partial skeleton of a juvenile, and it has been debated whether the specimen may be a juvenile mamenchisaurid.

Alocodon is a genus of ornithischian dinosaur known from multiple teeth from the Middle or Late Jurassic Cabaços Formation of Portugal, and also the Forest Marble and Chipping Norton Formations of England. A single species is known, A. kuehnei.

Jiangjunosaurus is an extinct genus of herbivorous stegosaurian dinosaurs from the Oxfordian-age (Upper Jurassic) Shishugou Formation of the Junggar Basin, Xinjiang, China.

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.

Gongbusaurus is a genus of ornithischian, perhaps ornithopod, dinosaur that lived between about 160 and 157 million years ago, in the Late Jurassic period. A small herbivore, it is very poorly known. Two species have been assigned to it, but as the original name is based on teeth, there is no concrete evidence to connect the two species. Its fossils have been found in China.

Serikornis is a genus of small, feathered anchiornithid dinosaur from the Upper Jurassic Tiaojishan Formation of Liaoning, China. It is represented by the type species Serikornis sungei. Some researchers believe it is a junior synonym of Anchiornis.

Hualianceratops is a genus of herbivorous ceratopsian dinosaur that lived about 160 million years ago in the Late Jurassic epoch in what is now western China. The single species, H. wucaiwanensis was described in 2015. Its size has been compared to that of a spaniel.

Cryptosaurus (meaning "hidden lizard") is a dubious genus of dinosaur known from a partial femur from the Late Jurassic of England. The sole species is Cryptosaurus eumerus.

Pulaosaurus (meaning "Pulao lizard") is an extinct genus of neornithischian dinosaur from the mid-Jurassic (Callovian–Oxfordian ages) Tiaojishan Formation of Hebei, China. The genus contains a single species, Pulaosaurus qinglong, known from a nearly complete articulated skeleton including the skull and soft tissue impressions. It is one of the only non-avian dinosaurs known to preserve a larynx (voicebox), suggesting it may have made bird-like vocalizations. Pulaosaurus is the first neornithischian named from the Yanliao Biota, though members of this clade have been known from other fossil be

Shishugounykus (meaning "Shishugou claw") is a genus of basal alvarezsaurian dinosaur from the Shishugou Formation of Xinjiang, China. The type and only species is Shishugounykus inexpectus. The specific name refers to the unexpected discovery of another species of alvarezsaur from the Shishugou Formation (other alvarezsaurs from this formation include Haplocheirus and possibly Aorun). Its affinities to alvarezsaurs have subsequently been questioned.

Vouivria is a genus of herbivorous sauropod dinosaur, belonging to the Brachiosauridae, that lived in the area of present France during the Late Jurassic. The type and only known species is Vouivria damparisensis. It is based on a specimen once commonly referred to as the '"French Bothriospondylus"' in the scientific literature, as the specimen was once identified as Bothriospondylus madagascariensis, a species known from the Middle Jurassic of Madagascar.

Priodontognathus (meaning "saw tooth jaw") is a genus of ankylosaurian dinosaur possibly from the Late Jurassic (Oxfordian-aged) Lower Calcareous Grit of Yorkshire, England. It is a dubious genus based on a maxilla, and has been erroneously mixed up with iguanodonts and stegosaurs.
