Huanghetitan, is a genus of sauropod dinosaur from the early Cretaceous Period. It was a basal titanosauriform which lived in what is now Gansu, China.
The Ziliujing Formation is a geological formation in China, It is Early Jurassic in age. It is part of the stratigraphy of the Sichuan Basin. The dinosaur Gongxianosaurus and indeterminate theropod material are known from the Dongyuemiao Member of the formation, as well as dinosaur footprints, Zizhongosaurus and indeterminate prosauropods from the Da'anzhai Member. The basal sauropod Sanpasaurus is known from the Maanshan Member. An unnamed stegosaur and the pliosauroid plesiosaur Sinopliosaurus are also known from this formation but they were found an indeterminate member. An unnamed teleosaurid known from a complete skull has also been found in the formation, pending a formal description. The deposition environment during the Da'anzhai Member in the lower Toarcian is thought to have been that of a giant freshwater lake encompassing the whole of the Sichuan basin, around 3 times larger than Lake Superior, coeval with the Toarcian Oceanic Anoxic Event around 183 Ma.
Zhongyuansaurus is a monospecific genus of ankylosaurid dinosaur from Henan that lived during the Early Cretaceous in what is now the Haoling Formation. Zhongyuansaurus is possibly a junior synonym of Gobisaurus, a basal ankylosaurid from the Ulansuhai Formation of Inner Mongolia.
Luanchuanraptor is a genus of dromaeosaurid theropod dinosaurs from the Late Cretaceous of China. The genus is based on a partial skeleton from the Qiupa Formation in Luanchuan, Henan. They were medium-sized dromaeosaurids, the first Asian dromaeosaurid taxa described from outside the Gobi Desert or northeastern China.
Ruyangosaurus is a genus of titanosauriform sauropod dinosaur recovered from the Early Cretaceous Haoling Formation of China. The type species is R. giganteus, described in 2009 by Lü Junchang et al.
The Xiaguan Formation is a Turonian to Campanian geologic formation in Henan Province of China. Dinosaur remains are among the fossils that have been recovered from the formation.
The Tangshang Formation is a Late Cretaceous Mesozoic geologic formation in China. Dinosaur and pterosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The formation has been dated around 92.9 million to 81.5 million years ago.
The Gaogou Formation is a fossiliferous geological formation located in the Xixia Basin of China. The formation dates back to the Late Cretaceous (Cenomanian-Coniacian) and fossilized eggs of dinosaurs and turtles are commonly reported from the formation. Dinosaur taxa is also reported from the unit.
Luoyanggia is a genus of oviraptorid dinosaur known from the Early Cretaceous Haoling Formation of the Ruyang Basin in Henan Province, central China. The type species is L. liudianensis. Holtz estimated it at 1.5 meters and around 2.27-9.1 kg. Molina-Pérez and Larramendi gave a similar size of 1.2 meters and 8.5 kg.
Xianshanosaurus is a genus of sauropod dinosaur from the Early Cretaceous (Aptian-Albian) of the Ruyang Basin in Henan Province, China. Its type and only species is Xianshanosaurus shijiagouensis. It was described in 2009 by a team of paleontologists led by Lü Junchang. Xianshanosaurus may be a titanosaur, and Daxiatitan may be its closest relative, but its evolutionary relationships remain controversial.
The Nanxiong Formation is a Late Cretaceous geologic formation in Guangdong Province. Dinosaur remains are among the fossils that have been recovered from the formation.
The Majiacun Formation is a Santonian to Coniacian geologic formation in China. Dinosaur remains are among the fossils that have been recovered from the formation.
Ovaloolithus is an oogenus of dinosaur egg. Eggs of the genus have been found in China, Mongolia and Utah.
Macroelongatoolithus is an oogenus of large theropod dinosaur eggs, representing the eggs of giant caenagnathid oviraptorosaurs. They are known from Asia and from North America. Historically, several oospecies have been assigned to Macroelongatoolithus, however they are all now considered to be a single oospecies: M. carlylensis.
Yulong is an extinct genus of derived oviraptorid theropod dinosaur known from the Late Cretaceous Qiupa Formation of Henan Province, central China. It contains a single species, Yulong mini. It is known from many juvenile specimens that represent some of the smallest known oviraptorids and also a single subadult specimen.
The Qiupa Formation is a Late Cretaceous Maastrichtian geologic formation in Henan Province, central China. It is rich in dinosaur eggs and bones, such as those of carnivorous and herbivorous dinosaurs. The Qiupa Formation is considered to be Late Maastrichtian in age, about 72 million and 66 million years ago.
Yunmenglong is an extinct genus of somphospondylan sauropod known from the late Early Cretaceous of Henan Province, central China. Its remains were discovered in the Haoling Formation of the Ruyang Basin. The type species is Yunmenglong ruyangensis, described in 2013 by Junchang Lü et al. on the basis of an incomplete postcranial skeleton. Yunmenglong shares some characters with Euhelopus, Qiaowanlong and Erketu, and a phylogenetic analysis places it as a sister taxon of Qiaowanlong, both grouped with Erketu in a position more derived than Euhelopus but basal to Titanosauria.
This timeline of oviraptorosaur research is a chronological listing of events in the history of paleontology focused on the oviraptorosaurs, a group of beaked, bird-like theropod dinosaurs. The early history of oviraptorosaur paleontology is characterized by taxonomic confusion due to the unusual characteristics of these dinosaurs. When initially described in 1924 Oviraptor itself was thought to be a member of the Ornithomimidae, popularly known as the "ostrich" dinosaurs, because both taxa share toothless beaks. Early caenagnathid oviraptorosaur discoveries like Caenagnathus itself were also incorrectly classified at the time, having been misidentified as birds.
Qiupanykus is a genus of alvarezsaurid coelurosaur theropod from the Late Cretaceous Qiupa Formation of southern China.
Yubaatar is a genus of multituberculate, an extinct order of rodent-like mammals, which lived in what is now China during the Late Cretaceous. The first specimen was discovered in the Qiupa Formation of Luanchuan County, in the Henan Province. The specimen consists of a partial skeleton with a nearly complete skull, and was made the holotype of the new genus and species Yubaartar zhongyuanensis by the Chinese palaeontologist Li Xu and colleagues in 2015. The generic name consists of the word Yu, which is the pinyin spelling of the Chinese character for the Henan Province, and the Mongolian word baatar, which means "hero", a word commonly used as suffix in the names of Asian multituberculates. The specific name comes from Zhongyuan, an ancient name for the geographic area of the province.
