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.

Paleontologist
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] |
Chaoyangsaurus
''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 transliteration ...

Sinraptor
''Sinraptor'' is a genus of metriacanthosaurid theropod dinosaur from the Late Jurassic. The name ''Sinraptor'' comes from the Latin prefix "Sino", meaning Chinese, and "raptor" meaning robber. The specific name ''dongi'' honours Dong Zhiming. Despite its name, ''Sinraptor'' is not related to dromaeosaurids (often nicknamed "raptors") like ''Velociraptor''. Instead, it was a carnosaur distantly related to ''Allosaurus''. ''Sinraptor'' and its close relatives were among the earliest members of the Jurassic carnosaurian radiation. ''Sinraptor'' still remains the best-known member of the family Metriacanthosauridae, with some older sources even using the name "Sinraptoridae" for the family. Discovery The holotype specimen of ''Sinraptor'' was uncovered from the Shishugou Formation during a joint Chinese/Canadian expedition to the northwestern Chinese desert in 1987, and described by Philip J. Currie and Zhao Xijin in 1993. Standing nearly tall and measuring roughly in length, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sangonghesaurus
''Tianchisaurus'' (meaning "heavenly pool lizard"), 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. Discovery and naming The holotype (IVPP V. 10614), discovered in 1974, consists of skull fragments, five cervicals, six dorsals, seven sacrals, and three caudals, limb fragments, scutes and some unidentifiable fragments. The type specimen was informally referred to as "Jurassosaurus" after the 1993 film ''Jurassic Park'', and the species epithet ''nedegoapeferima'' is formed from the surnames of the film's main stars: Sam Neill, Laura Dern, Jeff Goldblum, Richard Attenborough, Bob Peck, Marti ...

This list of informally named dinosaurs is a listing of dinosaurs (excluding Aves; birds and their extinct relatives) that have never been given formally published scientific names. This list only includes names that were not properly published (" unavailable names") and have not since been published under a valid name (see list of dinosaur genera for valid names). The following types of names are present on this list: * ''Nomen nudum'', Latin for "naked name": A name that has appeared in print but has not yet been formally published by the standards of the International Commission on Zoological Nomenclature. ''Nomina nuda'' (the plural form) are invalid, and are therefore not italicized as a proper generic name would be. * '' Nomen manuscriptum'', Latin for "manuscript name": A name that appears in manuscript but was not formally published.

Monolophosaurus
''Monolophosaurus'' ( ; meaning "single-crested lizard") is an extinct genus of tetanuran theropod dinosaur from the Middle Jurassic Shishugou Formation in what is now Xinjiang, China.Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> It was named for the single crest on top of its skull. ''Monolophosaurus'' was a mid-sized theropod at about long or more. Discovery and naming A nearly complete skeleton of a theropod new to science was discovered by Dong Zhiming in 1981, during stratigraphic exploration for the benefit of the oil industry. The fossil was not unearthed until 1984. In 1987, before description in the scientific literature, it was referred to in the press as ''Jiangjunmiaosaurus'', an invalid '' nomen nudum''. In 1992 it was mentioned by Dong Zhiming as ''Monolophosaurus jiangjunmiaoi'', and in 1993 by Wayne Grady as ''Monolophosaurus dongi''. These latter names also lacked a ...

Monkonosaurus
''Monkonosaurus'' (meaning " Monkon lizard") is a dubious genus of herbivorous stegosaurian dinosaur from the Late Jurassic/Early Cretaceous-aged Loe-ein Formation of Tibet (or the Early Cretaceous Lura Formation of China). Some sources place it as alive during the Oxfordian - Albian stages, around 163 - 100 million years ago, although ''Monkonosaurus'' was probably only alive during the Late Jurassic (163 – 152.1 ± 0.9 million years ago), making it among the earliest known stegosaurs along with ''Chungkingosaurus'' and '' Bashanosaurus''. Discovery and naming The genus was formalized by Zhao Xijin in 1986.X. Zhao. 1986. eptilia ''Ching-kuo Ti Pao o Hsi'' 'The Cretaceous System of China.
