Lake Aqqikkol is a saline lake in Xinjiang, China. [1] The lake falls within the borders of Ruoqiang County, and is noted as being a gathering place for local and migratory birds. [2] [3]
Shantungosaurus is a genus of very large saurolophine hadrosaurid dinosaur found in the Late Cretaceous Wangshi Group of the Shandong Peninsula in China, containing a single species, Shantungosaurus giganteus. The stratigraphic interval of Shantungosaurus ranges from the top of the Xingezhuang Formation to the middle of the Hongtuya Formation, middle to late Campanian in age. Shantungosaurus is so far the largest hadrosauroid taxon in the world: the greatest length of its femur is about 1.7 metres (5.6 ft), and the greatest length of its humerus is about 0.97 metres (3.2 ft).
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.
Huaxiapterus is a genus of tapejarid pterodactyloid pterosaur from the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. It is the second genus of tapejarid from this formation, after Sinopterus. Three species are known, though they may not actually form a natural group with each other. It was first named by Lü Junchang and Yuan Chongxi.
Omnivoropterygidae is a family of primitive avialans known exclusively from the Jiufotang Formation of China, though putative omnivoropterygids are known from the Maevarano Formation of the Maastrichtian of Madagascar. They had short skeletal tails and unusual skulls with teeth in the upper, but not lower, jaws. Their unique dentition has led some scientists to suggest an omnivorous diet for them. The family was named by Stephen A. Czerkas & Qiang Ji in 2002, though its junior synonym Sapeornithidae is often used instead, though it was named four years later in 2006. It is the only named family in the order Omnivoropterygiformes.
Eomamenchisaurus is a genus of mamenchisaurid sauropod dinosaur from the Middle Jurassic Zhanghe Formation of Yuanmou, Yunnan, China. The type species is E. yuanmouensis, described by Lü Junchang et al. in 2008.
The Xinlong Formation is an Early Cretaceous geologic formation in Guangxi, southern China.
The Haifanggou Formation is a fossil-bearing rock deposit located near Daohugou village of Ningcheng County, in Inner Mongolia, northeastern China.
Zhenyuanopterus is a genus of boreopterid pterosaur which is known from Lower Cretaceous Yixian Formation of Liaoning, China. It contains one species, Zhenyuanopterus longirostris, which was first described and named by Lü Junchang.
Rhamphorhynchidae is a group of early pterosaurs named after Rhamphorhynchus, that lived in the Late Jurassic. The family Rhamphorhynchidae was named in 1870 by Harry Govier Seeley.
Euctenochasmatia is an extinct group of pterodactyloid pterosaurs. It was named by David Unwin in 2003 as the group that contains the most recent common ancestor of Pterodactylus and Ctenochasma, and all their descendants.
Jianchangopterus is a genus of scaphognathine rhamphorhynchid pterosaur from the Middle Jurassic of western Liaoning, China. Jianchangopterus is known from a nearly complete skeleton with skull preserved. It was collected from the Tiaojishan Formation. It was first named by Lü Junchang and Bo Xue in 2011 and the type species is Jianchangopterus zhaoianus.
Shengjingornis is a genus of enantiornithean bird known from the Early Cretaceous of Jinzhou, western Liaoning, China. Its remains were discovered in Jiufotang Formation deposits, dated to 120 million years ago.
Xinghaiornis is an extinct genus of toothless basal ornithothoracine dinosaur known from the Early Cretaceous Yixian Formation of western Liaoning Province, northeastern China. Xinghaiornis was first named by Xuri Wang, Luis M. Chiappe, Fangfang Teng and Qiang Ji in 2013 and the type species is Xinghaiornis lini. Xinghaiornis was prepared by Maureen Walsh at the Dalian Museum of Prehistory, Dalian, China.
Pangupterus is a genus of pterodactyloid pterosaur from the Early Cretaceous Jiufotang Formation of China. It was first described and named by Lü Junchang et al.
Sinovenatorinae is a subfamily of the extinct bird-like troodontid dinosaurs known exclusively from the Early Cretaceous of China. It includes the genus Sinovenator as well as several related genera.
The Chaochuan Formation is a geologic formation in China. It is made up of purplish red calcarenaceous, muddy siltstone, fine-grained sandstone with interbeds of tuffaceous sandstone and conglomerate or rhyolitic tuff.
Luopterus is an extinct genus of anurognathid pterosaur containing only the holotype species L. mutoudengensis that is known from the Middle Jurassic Tiaojishan Formation of Qinglong, northern Hebei Province, China. It was originally named as a species of Dendrorhynchoides in 2012 but it was moved to the genus Luopterus in 2020. Luopterus was originally thought to be from the Early Cretaceous, with a wingspan that is about 40 centimeters (16 in), making it one of the smallest known pterosaurs.
Grabauornis is an extinct genus of enantiornitheans from the Early Cretaceous of China.
Dinocephalosauridae is an extinct clade of marine and terrestrial archosauromorph reptiles that lived throughout the Triassic period. Like tanystropheids, they are characterized by their long necks, lengthened by either addition of cervical vertebrae or elongation of the individual bones.
Dawazisaurus is an extinct genus of sauropterygian of possible nothosauroid affinities from the Middle Triassic Guanling Formation in China. The type species is D. brevis.
