Wulatelong
''Wulatelong'' is an extinct genus of basal oviraptorid dinosaur known from the Late Cretaceous Wulansuhai Formation (Campanian stage) of Bayan Mandahu, Linhe District of Inner Mongolia, northern China. It contains a single species, ''Wulatelong gobiensis''. History The fossils of ''Wulatelong'', representing a single nearly-complete skeleton, now cataloged IVPP V 18409, were discovered in 2009 in the Bayan Mandahu area of Wulatehouqi, Inner Mongolia, a fossil-rich area which has yielded many recent dinosaur discoveries. The authors of the paper describing ''Wulatelong'' had previously described the dromaeosaurid ''Linheraptor'' (2010), the alvarezsaurid ''Linhenykus'' (2011), and the troodontid ''Linhevenator'' (2011). ''Wulatelong'' was described by Xu ''et al.'' in 2013. The generic name derives from ''Wulate'', where the fossils were discovered, and ''long'', the Chinese word for "dragon". The specific name, ''gobiensis'', refers to the Gobi Desert. Classification ''Wulatel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bayan Mandahu
The Bayan Mandahu Formation (also known as Wulansuhai Formation or Wuliangsuhai Formation) is a geological unit of "redbeds" located near the village of Bayan Mandahu in Inner Mongolia, China Asia ( Gobi Desert) and dates from the late Cretaceous Period. Laid down in the Campanian, it is dated somewhat uncertainly to between 75 and 71 mya (million years ago). Description The paleoenvironment it preserves was semi-arid and characterized by alluvial (stream-deposited) and eolian (wind-deposited) sediments. The formation is known for its vertebrate fossils, most of which are preserved in unstructured sandstone, indicating burial by wind-blown sandstorms. Paleofauna of the Bayan Mandahu Formation The fauna of the Bayan Mandahu is very similar in composition to the nearby Djadochta Formation, and the two may have been deposited at roughly the same time. These two formations share many of the same genera, but differ in the makeup of species. For example, the most common mammal in ...

Oviraptoridae
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 eye, ...

Citipati Osmolskae
''Citipati'' (; meaning "funeral pyre lord") is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period, about 75 million to 71 million years ago. It is mainly known from the Ukhaa Tolgod locality at the Djadokhta Formation, where the first remains were collected during the 1990s. The genus and type species ''Citipati osmolskae'' were named and described in 2001. A second species from the adjacent Zamyn Khondt locality may also exist. ''Citipati'' is one of the best-known oviraptorids thanks to a number of well-preserved specimens, including individuals found in brooding positions atop nests of eggs, though most of them were initially referred to the related ''Oviraptor''. These nesting specimens have helped to solidify the link between non-avian dinosaurs and birds. ''Citipati'' was among the largest oviraptorids; it is estimated to have been around in length and to have weighed . Its skull was highly pneumatized, short, and had a characteristic c ...

Nankangia Jiangxiensis
''Nankangia'' is an extinct genus of caenagnathoid oviraptorosaurian dinosaur known from the Upper Cretaceous Nanxiong Formation of Nankang County, Ganzhou City of Jiangxi Province, southeastern China. It contains a single species, ''Nankangia jiangxiensis''. ''N. jiangxiensis'' coexisted with at least four other caenagnathoids, including but not limited to ''Corythoraptor'', '' Banji long'', ''Ganzhousaurus nankangensis'' and ''Jiangxisaurus ganzhouensis''. The relatively short dentary and non-downturned mandibular symphysis of ''Nankangia'' suggest that it may have been more herbivorous than carnivorous. Its diet consisted of leaves and seeds. Discovery ''Nankangia'' was first described and named by Lü Junchang, Yi Laiping, Zhong Hui and Wei Xuefang in 2013 and the type species is ''Nankangia jiangxiensis''. The generic name honors the Chinese administrative unit Nankang County in Jiangxi Province, and the specific name honors the province where the holotype site in Nankan ...

Gobi Desert
The Gobi Desert (Chinese: 戈壁 (沙漠), Mongolian: Говь (ᠭᠣᠪᠢ)) () is a large desert or brushland region in East Asia, and is the sixth largest desert in the world. Geography The Gobi measures from southwest to northeast and from north to south. The desert is widest in the west, along the line joining the Lake Bosten and the Lop Nor (87°–89° east). In 2007, it occupied an arc of land in area. In its broadest definition, the Gobi includes the long stretch of desert extending from the foot of the Pamirs (77° east) to the Greater Khingan Mountains, 116–118° east, on the border of Manchuria; and from the foothills of the Altay, Sayan, and Yablonoi mountain ranges on the north to the Kunlun, Altyn-Tagh, and Qilian mountain ranges, which form the northern edges of the Tibetan Plateau, on the south. A relatively large area on the east side of the Greater Khingan range, between the upper waters of the Songhua (Sungari) and the upper waters of the Liao-h ...

Yulong Mini
''Yulong'' is an extinct genus of derived oviraptorid theropod dinosaur known from the Late Cretaceous Qiupa Formation of Henan Province, central China. It contains a single species, ''Yulong mini''. It is known from many juvenile specimens that represent some of the smallest known oviraptorids and also a single subadult specimen. Discovery and naming Specimens of ''Yulong'' were collected near Qiupa Town in Luanchuan County, Henan Province, from the Qiupa Formation. The exact geological age of the Qiupa Formation is unknown, but it probably dates to the Late Cretaceous based on the presence of oviraptorids (''Yulong''), dromaeosaurids (''Luanchuanraptor''), ornithomimids (''Qiupalong''), alvarezsaurs (''Qiupanykus'') and other, undescribed, derived dinosaur specimens. ''Yulong'' was first described and named by Junchang Lü, Philip J. Currie, Li Xu, Xingliao Zhang, Hanyong Pu and Songhai Jia in 2013 and the type species is ''Yulong mini''. The generic name is derived fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caenagnathidae
Caenagnathidae is a family of bird-like maniraptoran theropod dinosaurs from the Cretaceous of North America and Asia. They are a member of the Oviraptorosauria, and close relatives of the Oviraptoridae. Like other oviraptorosaurs, caenagnathids had specialized beaks, long necks, and short tails, and would have been covered in feathers. The relationships of caenagnathids were long a puzzle. The family was originally named by Raymond Martin Sternberg in 1940 as a family of flightless birds. The discovery of skeletons of the related oviraptorids revealed that they were in fact non-avian theropods, and the discovery of more complete caenagnathid remains revealed that ''Chirostenotes pergracilis'', originally named on the basis of a pair of hands, and ''Citipes elegans'', originally thought to be an ornithomimid, named from a foot, were caenagnathids as well. Anatomy Overall, the anatomy of the caenagnathids is similar to that of the closely related Oviraptoridae, but there are a n ...

Caenagnathoidea
Caenagnathoidea ("recent jaw forms") is a group of advanced oviraptorosaurian dinosaurs from the Cretaceous Period (geology), Period of what are now Asia and North America. They are distinct for their characteristically short, beaked, parrot-like skulls, often with bony crests atop the head. They ranged in size from ''Caudipteryx'', which was the size of a turkey, to the 8 meter long, 1.4 ton ''Gigantoraptor''.Xu, X., Tan, Q., Wang, J., Zhao, X., and Tan, L. (2007). "A gigantic bird-like dinosaur from the Late Cretaceous of China." ''Nature'', 447: 844-847. The group (along with all maniraptoran dinosaurs) is close to the ancestry of birds. The most complete specimens have been found in Asia, representing members of the sub-group Oviraptorinae. Notable but fragmentary remains are also known from North America, almost all of which belong to the subgroup Elmisaurinae.Varricchio, D. J. 2001.
