Xu Xing (paleontologist)
Xu Xing (; born July 1969) is a Chinese paleontologist who has named more dinosaurs than any other living paleontologist. Such dinosaurs include the Jurassic ceratopsian ''Yinlong'', the Jurassic tyrannosauroid ''Guanlong'', the large oviraptorosaur ''Gigantoraptor'', and the troodontid '' Mei''. Biography Xing was born in Xinjiang, China, in 1969. A graduate from the department of geology of Peking University, he is currently a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences in Beijing. He had originally planned to become an economist. However, he was assigned to the department of geology by the Chinese authorities. He graduated in 1995, and claims inspiration from Roy Chapman Andrews. Among Xu's paleontological contributions have been discovery and analysis of dinosaur fossils with avian characteristics, and development of theories in regarding the evolution of feather Feathers are epidermal growths that for ...

Paleontology
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, ( gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeovolans
''Yanornis'' () is an extinct genus of fish-eating Early Cretaceous birds. Two species have been described, both from Liaoning province, China: ''Yanornis martini'', based on several fossils found in the 120-million-year-old Jiufotang Formation at Chaoyang, and ''Yanornis guozhangi'', from the 124-million-year-old Yixian Formation. Description ''Y. martini'' was the size of a chicken,Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> had a long skull with about 10 teeth in the upper jaw and 20 teeth in the lower jaw, and was both able to fly and walk well, having a well-developed U-shaped furcula (wishbone). The absence of the prefrontal bone and the non-diapsid skull allows ''Yanornis'' to be classified as an ornithuromorph, a member of a group of stem-birds which also includes the common ancestor of living birds. Similarly, its scapula and coracoid had evolved the basic shape and layo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dilong (dinosaur)
''Dilong'' (帝龍, which means 'emperor dragon') is a genus of basal tyrannosauroid dinosaur. The only species is ''Dilong paradoxus''. It is from the Lower Cretaceous Yixian Formation near Lujiatun, Beipiao, in the western Liaoning province of China. It lived about 126 million years ago. Discovery ''Dilong'' was described by Xu Xing and colleagues in 2004. The name is derived from the Chinese 帝 ''dì'' meaning 'emperor' and 龙 / 龍 ''lóng'' meaning 'dragon'. "Di", "emperor", refers to the relationship of this animal to ''Tyrannosaurus rex'', the "king" tyrannosaurid. "Long" is used to name Chinese dinosaurs in much the same way that the Latin ''-saur'' is in the West. The specific name, ''paradoxus'', is a Latinisation of the Ancient Greek παράδοξον meaning 'against received wisdom'. Description The type specimen is IVPP 14243 (Institute of Vertebrate Paleontology and Paleoanthropology in Beijing), a nearly complete, semi-articulated, skull and skeleton. Referr ...

Chaoyangsaurus BW
''Chaoyangsaurus'' (" Chaoyang lizard") is a marginocephalian dinosaur from the Late Jurassic of China. It has been dated to between 150.8 and 145.5 million years ago. ''Chaoyangsaurus'' belonged to the Ceratopsia (Greek for "horned faces"). ''Chaoyangsaurus'', like all ceratopsians, was primarily a herbivore. Discovery and naming In 1976, the remains of ''Chaoyangsaurus'' were found by Cheng Zhengwu at Ershijiazi, in the Chaoyang area of Liaoning Province in northeastern China. The fossil was added to a travelling exhibition. Unlike many other dinosaurs, ''Chaoyangsaurus'' had been discussed in a number of sources before its official publication. As a result of this, several different spellings of its name have come and gone as invalid ''nomina nuda'' ("naked names", names with no formal description behind them). The first name to see print was ''Chaoyoungosaurus'', which appeared in the guidebook to a Japanese museum exhibit, and was the result of an incorrect translitera ...

Zhao Xijin
Zhao Xijin (赵喜进; born c. 1935 died July 21, 2012) was a Chinese paleontologist notable for having named numerous dinosaurs. He was a professor at Beijing's Institute of Vertebrate Paleontology and Paleoanthropology. Biography Zhao Xijin was born ''c.''1935 in China. Career Paul Sereno and Zhao went on a dinosaur fossil hunt in 2005 to Tibet to look for a site that Zhao had found 27 years prior. Before this hunt, in 2001, they had been engaged in a dig in the Gobi Desert. This involved a rock quarry that led them to finding 25 skeletons of the species '' Sinornithomimus dongi''. In 2008, Zhao was involved in and in charge of a dig in Zhucheng that consisted of digging out a "980 ft-long pit". The site has unearthed more than 7,600 fossils through Xijin's work. It is believed to be the largest such site in the world. The majority of the fossils found appeared to be from the Late Cretaceous period. He died in 2012 at the age of 77.

Beipiaosaurus Restoration
''Beipiaosaurus'' is a genus of therizinosauroid theropod dinosaurs that lived in Asia during the Early Cretaceous in the Yixian Formation. The first remains were found in 1996 and formally described in 1999. Before the discovery of ''Yutyrannus'', they were among the heaviest dinosaurs known from direct evidence to be feathered. ''Beipiaosaurus'' is known from three reported specimens preserving numerous impressions of feather structures that allowed to determine the feathering color which turned out to be brownish. They were relatively small-sized therizinosaurs, measuring long and weighing about in contrast to the advanced and giant ''Segnosaurus'' or ''Therizinosaurus''. The necks of ''Beipiaosaurus'' were shorter than in most therizinosaurs, whose are characterized by elongated necks adapted for high-browsing. Also, their feet configuration differs from therizinosaurids, having a generic three-toed pes instead of four as seen in other members. The exact classification of ...
