Heyuannia
''Heyuannia'' ("from Heyuan") is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous epoch, in what is now China and Mongolia. It was the first oviraptorid found in China; most others were found in neighbouring Mongolia. Two species are known: ''H. huangi'', named by Lü Junchang in 2002 from the Dalangshan Formation; and ''H. yanshini'', originally named as a separate genus ''Ingenia'' from the Barun Goyot Formation by Rinchen Barsbold in 1981, and later renamed to ''Ajancingenia'' in 2013 due to the preoccupation of ''Ingenia''. The latter name was eventually discarded due to various ethical issues surrounding the author. Discovery and naming ''H. huangi'' The type species, ''Heyuannia huangi'', was named and described by Lü Junchang in 2002. The generic name refers to the city of Heyuan. The specific name (zoology), specific name honours Huang Dong, the director of the Heyuan Museum. The holotype, HYMV1-1, was discovered in Guangdong near Huangsha i ...

Oviraptorid
Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs. Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests. They were generally small, measuring between one and two metres long in most cases, though some possible oviraptorids were enormous. Oviraptorids are currently known only from the Late Cretaceous of Asia, with the most well-known species and complete specimens found only in the Gobi Desert of Mongolia and northwestern China. Description The most characteristic feature of this group is the skull structure. Oviraptorids had short snouts and very deep mandibles. Some taxa (such as ''Citipati'', '' Corythoraptor'', ''Rinchenia'') had a midline crest on top of the skull, resembling that of a cassowary. Other distinguishing characteristics include a bony spike intruding on the mandibular fenestra, nostrils placed very high and far back on the snout, an extremely thin bony bar beneath the e ...

Rinchen Barsbold
Rinchen Barsbold (, Rinchyengiin Barsbold, born December 21, 1935, in Ulaanbaatar) is a Mongolian paleontologist and geologist. He works with the Institute of Geology, at Ulaanbaatar, Mongolia. He is an expert in vertebrate paleontology and Mesozoic stratigraphy. Barsbold has been instrumental in the discovery and recovery of one of the largest dinosaur collections in the world. His work has helped to form a more modern understanding of the later stages of dinosaur evolution in Eurasia. Barsbold has had considerable influence on dinosaur paleontology in the Communist world. His scientific work has made him a leading authority on theropods of the Gobi Desert, starting with his doctoral dissertation on these dinosaurs. As early as 1983, he noted that in different lineages of theropods, many features previously only known from birds had evolved in various combinations (Barsbold 1983). He postulated that as a result of this "ornithization", one or several lineages of theropods that h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lü Junchang
Lü Junchang (; 1965 – 9 October 2018) was a Chinese palaeontologist and professor at the Institute of Geology, Chinese Academy of Geological Sciences. An expert on Mesozoic reptiles, he described and named dozens of dinosaur and pterosaur taxa including '' Tongtianlong'', '' Qianzhousaurus'', '' Heyuannia'', '' Gannansaurus'', '' Yunnanosaurus youngi'', and ''Darwinopterus.'' Biography Lü was born in 1965. He graduated from Lanzhou University in 1989 with a bachelor's degree in geology. He studied at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences from 1997 to 2000 and earned his master's degree. He subsequently went to the United States to study at the Department of Earth Sciences at the Southern Methodist University, earning his Ph.D. in 2004. Lü began working for the Chinese Academy of Geological Sciences in July 2004, initially as a postdoctoral researcher, then as associate professor and eventually as professor ...

Conchoraptor
''Conchoraptor'' (meaning "conch plunderer") is a genus of oviraptorid dinosaurs that lived in Asia during the Late Cretaceous epoch, about 70 million years ago. It is known from the Barun Goyot and Nemegt Formation, Nemegt formations of Mongolia. Discovery When first discovered in the Red Beds of Hermiin Tsav of the Early Maastrichtian Nemegt Formation by a Polish-Mongolian expedition in 1971, scientists believed that ''Conchoraptor'' was a juvenile ''Oviraptor'' and that the animal's missing crest would have begun to grow when the animal reached sexual maturity. Further study of multiple skeletons showed that ''Conchoraptor'' belonged to a new genus. The hands of ''Conchoraptor'' were a major reason scientists decided to split it off from ''Oviraptor''. Anatomically the hands seemed to be an evolutionary intermediate between those of ''Ajancingenia'' and ''Oviraptor'', making it obvious that this animal was not a member of a known species. The type species of this new genus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barun Goyot Formation
The Baruungoyot Formation (also known as Barun Goyot) is a geological formation dating to the Late Cretaceous Period. It is located within and is widely represented in the Gobi Desert Basin, in the Ömnögovi Province of Mongolia. Description It was previously known as the Lower Nemegt Beds occurring beneath the Nemegt Formation and above the Djadokhta Formation. It has been suggested that the Djadokhta and Baruungoyot Formations are lower and upper parts, respectively, of the same lithological unit and the boundary between the two does not exist. The stratotype of the Baruungoyot Formation is the Khulsan locality, east of Nemegt. At Nemegt, only the uppermost barungoyotian beds are visible. The ''Red Beds of Khermeen Tsav'' are also considered part of the Baruungoyot Formation. It is approximately in thickness,Gradzinski, R.; & Jerzykiewicz, T. (1974).
