Tianchisaurus, also invalidly called Tianchiasaurus and "Jurassosaurus", is a genus of ankylosaurian dinosaur from the Late Jurassic (Oxfordian–Kimmeridgian)-aged Toutunhe Formation of China. If it actually belongs to the family Ankylosauridae as proposed by Dong Zhiming, it would be the second earliest member of that family, being slightly younger than Spicomellus. Unlike other ankylosaurids, it lacked a bony club at the tip of its tail.
Xiaosaurus, is a genus of small herbivorous dinosaur from the middle Jurassic, approximately 169 to 163.5 mya. Xiaosaurus lived in what is now the Sichuan Basin of China.
Asiatosaurus is an extinct genus of herbivorous sauropod dinosaur which lived during the Early Cretaceous in Mongolia and China. The type species is known only from teeth, making it difficult to rely on information until more specimens are found to expand our knowledge, and another species is known, also based on scant remains; both are now classified as nomina dubia.
Sinosaurus is an extinct genus of theropod dinosaur which lived during the Early Jurassic Period. It was a bipedal carnivore approximately 5.5 metres (18 ft) in length and 300 kilograms (660 lb) in body mass. Fossils of the animal were found at the Lufeng Formation, in the Yunnan Province of China.
Eoenantiornis is a genus of enantiornithean birds which lived during the early Cretaceous period. It is known from a single fossil specimen found in the Yixian Formation in Liaoning province, China.
Chinchenia is an extinct genus of a basal pistosauroid known from the Middle Triassic of Guizhou Province, southwestern China. It contains a single species, Chinchenia sungi.
Pachysuchus is a dubious extinct genus of basal sauropodomorph dinosaur from the Early Jurassic of China.
Wanosuchus is an extinct genus of sebecosuchian mesoeucrocodylian known from Paleocene-age rocks of southern Anhui, China. It is based on IVPP V 6262, a nearly complete lower jaw, which is also the only known specimen. The bone lacks an external mandibular fenestra and has thirteen teeth, the longest of which are the fourth and eleventh. It was collected between 1970 and 1972 by Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) personnel; the exact location and rock unit that produced the bone are uncertain. Wanosuchus was named in 1981 by Zhang Fakui of the IVPP. The type species is W. atresus, a reference to the absent fenestra. Zhang classified Wanosuchus under its own family within Sebecosuchia, Wanosuchidae. It shares some characteristics with Doratodon, a crocodyliform from the Late Cretaceous of Europe.
Dromotectum is an extinct genus of bystrowianid reptiliomorph from the Late Permian of China and Early Triassic of Russia. Two species have been named: the type species D. spinosum and the species D. largum. D. spinosum, the first species to be named, comes from Lower Triassic deposits in the Samara Region of European Russia and is known from the holotype PIN 2424/23, which consists of armor scutes, and from PIN 2424/65, 4495/14 and 2252/397. It was found in the Staritskaya Formation of the Rybinskin Horizon and named by I.V. Novikov and M.A. Shishkin in 2000. The generic name means “corridor with hipped vault” + “roof” (tecton), and the specific name means “spinous”. A second species, D. largum, was named by Liu Jun, Xu Li, Jia Song-Hai, Pu Han-Yong, and Liu Xiao-Ling in 2014 from the Shangshihezi Formation near Jiyuan in Henan province, China on the basis of specimen IVPP V 4013.1, a large scute.
Anshunsaurus is a genus of thalattosaurs within the family Askeptosauridae. Fossils have been found from Middle Triassic deposits in Guizhou, China. Three species are known: the type species A. huangguoshuensis, the slightly older species A. wushaensis, and the species A. huangnihensis.
Diandongosaurus is an extinct genus of eosauropterygian known from the lower Middle Triassic of Yunnan Province, southwestern China. It is known from the holotype IVPP V 17761, a complete and articulated skeleton with skull, which was found in the middle Triassic Lagerstätte of the Guanling Formation. It was first named by Qing-Hua Shang, Xiao-Chun Wu, Cun Li in 2011 and the type species is Diandongosaurus acutidentatus. A referred specimen suggests a total body length of 34 cm (13 in).
Shaanbeikannemeyeria is an extinct genus of dicynodont known from the Early Triassic of China. It contains a single species, S. xilougoensis, which was described in 1980 by Zheng-Wu Cheng from a skull catalogued as IGCAGS V315. The specimen was lost, and a neotype skull IVPP V 11674 was later designated. A second species, S. buergondia, was named by Jin-Lin Li in 1980 from a partial skeleton, but it has since been regarded as a synonym of S. xilougoensis.
Guchengosuchus is an extinct genus of erythrosuchid archosauriform from the Early Triassic of China. It is known from a single holotype skeleton called IVPP V 8808, described in 1991 from the lower Ermaying Formation in Shanxi. The lower Ermaying Formation dates back to the Olenekian stage of the Early Triassic, making Guchengosuchus one of the earliest archosauriforms. IVPP V 8808 is a disarticulated skeleton including a partial skull, lower jaw, some vertebrae, a scapula, and forelimb bones. Like some other erythrosuchids, Guchengosuchus has a tall skull with a notch between the premaxilla and maxilla bones of the upper jaw. The ribs of Guchengosuchus each have three heads, a feature also seen in the Russian erythrosuchid Vjushkovia. When it was first described, Guchengosuchus was placed in the suborder Proterosuchia, a group that included the families Erythrosuchidae, Proterosuchidae, and Proterochampsidae and was thought to be closely related to a primitive group of reptiles called Eosuchia. Proterosuchia is now considered a paraphyletic assemblage of basal archosauriforms representing a series of successive branches of stem group archosaurs.
Xinpusaurus is an extinct genus of thalattosaur from the Late Triassic of Guanling in Guizhou, China. Several species have been named since 2000: the type species X. suni along with the species X. bamaolinensis and X. kohi. A 2013 study proposed that all three species are synonymous with each other, in which case X. suni would be the only valid species, although a 2014 study argued that X. kohi was also valid. A fourth species, X. xingyiensis, was described in 2016.
Meemann Chang also known as Zhang Miman, is a Chinese paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP). She completed her undergraduate studies at Moscow University and completed her PhD thesis entitled 'The braincase of Youngolepis, a Lower Devonian crossopterygian from Yunnan, south-western China' at Stockholm University. She was the first woman to become head of IVPP in 1983. Later in 2011 she also received an honorary degree from the University of Chicago for her many career achievements.
Urtinotherium is an extinct genus of paracerathere mammals. It was a large animal that was closely related to Paraceratherium, and found in rocks dating from the Late Eocene to Early Oligocene period. The remains were first discovered in the Urtyn Obo region in Inner Mongolia, which the name Urtinotherium is based upon. Other referred specimens are from northern China.
Sanchiaosaurus is an extinct genus of a basal nothosauroid known from the Middle Triassic of Guizhou Province, southwestern China. It contains a single species, Sanchiaosaurus dengi.
Kwangsisaurus is an extinct genus of a basal pistosauroid known from the Early or Middle Triassic of Guangxi, southern China. It contains a single species, Kwangsisaurus orientalis.
Phymolepis is an extinct genus of yunnanolepidid placoderm from the Early Devonian of China. The type species, P. cuifengshanensis, was named by Zhang Goroui in 1978 and was re-evaluated in 2018, while a second species, P. guoruii, was named and described in 1996.
Austronaga is an extinct genus of dinocephalosaurid archosauromorph reptile from the Middle Triassic (Anisian) Guanling Formation of China. The genus contains a single species, A. minuta, known from a partial skull, as well as vertebrae from the tail and neck. Austronaga was significantly smaller than the coeval Dinocephalosaurus.
