WArchaeoceratops, meaning "ancient horned face", is a genus of basal neoceratopsian dinosaur from the Early Cretaceous of north central China. It appears to have been bipedal and quite small with a comparatively large head. Unlike many later ceratopsians it had no horns, possessing only a small bony frill projecting from the back of its head.
WAuroraceratops, meaning "dawn horned face", is a genus of bipedal basal neoceratopsian dinosaur, from the Early Cretaceous of north central China and South Korea. The etymology of the generic name refers to its status as an early ceratopsian and also to Dawn Dodson, wife of Peter Dodson, one of the palaeontologists who described it.
WBaishiya Karst Cave is a Tibetan Buddhist sanctuary and a high-altitude paleoanthropological site located on the northeastern edge of the Tibetan Plateau in Xiahe County, Gansu, China. This karst cave is the site of the discovery of the earliest hominin fossil found on the Tibetan Plateau, the Xiahe mandible. The mandible, by way of palaeoproteomic analysis, is the first confirmed discovery of a Denisovan fossil outside of Denisova Cave. This fossil discovery shows that archaic hominins were present in a high-altitude, low-oxygen environment by around 160,000 years ago.
WBeishanlong is a genus of giant ornithomimosaurian theropod dinosaur from the Early Cretaceous of China.
WChangmaornis is an extinct genus of basal ornithuromorph dinosaur known from the Early Cretaceous Xiagou Formation of Changma Basin, Gansu Province of northwestern China. Changmaornis was first named by Ya-Ming Wang, Jingmai K. O'Connor, Da-Qing Li and Hai-Lu You in 2013 and the type species is Changmaornis houi.
WDaxiatitan is a genus of titanosaur sauropod dinosaur from the Lower Cretaceous of Lanzhou Basin, Gansu Province, northwestern China. It is known from fossils including several neck vertebrae, a shoulder blade, and a thigh bone.
WEquijubus, is a genus of herbivorous hadrosauroid dinosaur from the Early Cretaceous of northwestern China.
WThe Gansu Provincial Museum is a museum in Lanzhou, China. Its collections include over 350,000 artefacts, in two main sections: history and natural science. Since its foundation, the museum has held almost 300 exhibitions, and items from its collections have been exhibited worldwide. The museum was originally only for the history of Gansu itself, but was re-purposed in 1956 to be a natural history museum, after three years of renovations.
WGongpoquansaurus is an extinct genus of basal hadrosauroid dinosaur that was not formally named until 2014, while the name was a nomen nudum for many years previously. It is known from IVPP V.11333, a partial skull and postcranial skeleton. It was collected in 1992 at locality IVPP 9208–21, from the Albian Zhonggou Formation, in Mazongshan, Gansu Province, China. The specimen was first described and named by Lü Junchang in 1997 as the third species of Probactrosaurus, Probactrosaurus mazongshanensis. Following its description, several studies found it to be less derived than the type species of Probactrosaurus in relation to Hadrosauridae. Therefore, "Gongpoquansaurus" had been suggested, yet informally, as a replacement generic name. In 2014, the species was formally redescribed, and the describers erected Gongpoquansaurus.
WHuanghetitan, is a genus of sauropod dinosaur from the early Cretaceous Period. It was a basal titanosauriform which lived in what is now Gansu, China.
WJintasaurus is a genus of hadrosauriform dinosaur described by Hai-Lu You and Da-Qing Li in 2009. The type species is J. meniscus. Jintasaurus lived during the Early Cretaceous of what is now Gansu, northwestern China. The fossils were discovered in Jinta County, Jiuquan, Gansu, China. The discovery supports the theory that hadrosaurs originated in Asia. The holotype and only known specimen includes the postorbital skull, lacking the jugal and quadratojugal.
WJiuquanornis is an extinct genus of basal ornithuromorph dinosaur known from the Early Cretaceous Xiagou Formation of Changma Basin, Gansu Province of northwestern China. Jiuquanornis was first named by Ya-Ming Wang, Jingmai K. O'Connor, Da-Qing Li and Hai-Lu You in 2013 and the type species is Jiuquanornis niui.
WLanzhousaurus is a genus of ornithopod dinosaur. Lanzhousaurus lived in the Gansu region of what is now China during the Early Cretaceous (Barremian). A partial skeleton has been recovered from the Hekou Group. It was described by You, Ji and Li in 2005 and the type and only species is Lanzhousaurus magnidens. It's been estimated to be about 10 meters in length and 6 tonnes in weight.
WPsittacosaurus is a genus of extinct ceratopsian dinosaur from the Early Cretaceous of what is now Asia, existing between 126 and 101 million years ago. It is notable for being the most species-rich dinosaur genus. Up to 12 species are known, from across China, Mongolia, Siberia, and possibly Thailand and Laos. The species of Psittacosaurus were obligate bipeds at adulthood, with a high skull and a robust beak. One individual was found preserved with long filaments on the tail, similar to those of Tianyulong, and scales across the rest of the animal. Psittacosaurus probably had complex behaviours, based on the proportions and relative size of the brain. It may have been active for short periods of time during the day and night, and had well-developed senses of smell and vision.
WQiaowanlong is a genus of sauropod dinosaur. Fossils belonging to the genus were found in 2007 from the Yujinzi Basin of Gansu, China, and were described in 2009 in the Proceedings of the Royal Society B. The remains come from a geological formation called the Xinminpu Group, dating to the Early Cretaceous about 100 Ma. The only known specimen consists of articulated cervical (neck) vertebrae and a right pelvic girdle, as well as several unidentified bone fragments. Qiaowanlong was initially reported as the first brachiosaurid to have been found from China. However, later analysis found that it was more closely related to titanosauriformes like Euhelopus and Erketu. It is estimated to have had a length of around 12 metres (39 ft) and would have weighed around 6 tonnes. The type species is Q. kangxii.
WSuzhousaurus is a genus of large therizinosauroid dinosaur from the Early Cretaceous of China. The genus is known from two specimens discovered on the Xiagou Formation and Zhonggou Formation—which are situated in the Xinminbao Group. These findings were made during field-works in 1999 and 2004. Though Suzhousaurus is known from these two specimens, an earlier named and described therizinosauroid from the adjacent basin, "Nanshiungosaurus" bohlini, may be synonymous with the former. However, Suzhousaurus can not be compared to this species due to non-overlapping material and the loss of the same. Moreover, this synonymy will result in Suzhousaurus bohlini with "N". bohlini having priority.
WThe Xiagou Formation is the middle strata of the Xinminbao Group. It is named for its type site in Xiagou, in the Changma Basin of Gansu Province, northwestern China and is considered Early Cretaceous in age. It is known outside the specialized world of Chinese geology as the site of a Lagerstätte in which the fossils were preserved of Gansus yumenensis, the earliest true modern bird.
WThe Xiahe mandible is a hominin fossil jaw (mandible) discovered in Baishiya Karst Cave, located on the northeastern edge of the Tibetan Plateau in Xiahe County, Gansu, China. By the use of palaeoproteomic analysis, it is the first confirmed discovery of a Denisovan fossil outside of Denisova Cave, and the most complete known Denisovan fossil. This fossil discovery shows that archaic hominins were present in a high-altitude, low-oxygen environment by around 160,000 years ago. Discover, Science News and Nova all named the discovery of the mandible in their lists of Top Science Stories of 2019.
WXiongguanlong is a genus of tyrannosauroid dinosaur that lived in the Early Cretaceous of what is now China. The type species is X. baimoensis, described online in 2009 by a group of researchers from China and the United States, and formally published in January 2009. The genus name refers to the city of Jiayuguan, a city in northwestern China. The specific name is derived from bai mo, "white ghost", after the "white ghost castle", a rock formation near the fossil site. The fossils include a skull, vertebrae, a right ilium and the right femur. The rocks it was found in are from the Aptian to Albian stages of the Cretaceous, between 125 and 100 million years ago.
WXuwulong is a genus of hadrosauroid dinosaur from the Early Cretaceous period. It lived during the early Cretaceous period in what is now Yujingzi Basin in the Jiuquan area, Gansu Province of northwestern China. It is known from the holotype – GSGM F00001, an articulated specimen including a complete cranium, almost complete axial skeleton, and complete left pelvic girdle from Xinminpu Group. Xuwulong was named by You Hailu, Li Daqing and Liu Weichang in 2011 and the type species is Xuwulong yueluni; the binomial name as a whole refers to Professor Wang Yue-lun; "Xu-wu" is his courtesy name.
