Udanoceratops
''Udanoceratops'' (meaning "Udan's horned face") is a genus of large leptoceratopsid dinosaur that lived during the Late Cretaceous period of Mongolia, in what is now the Djadokhta Formation. Discovery ''Udanoceratops'' was first named and described by Russian paleontologist Sergei Kurzanov in 1992 and the type species is ''Udanoceratops tschizhovi''. The holotype (PIN 3907/11) was collected during the 1980s at the Udan Sayr (also spelled Udyn Sayr or Üüden Sair) locality of the Djadokhta Formation in Ömnögovi Province, dating to the Campanian stage of the Late Cretaceous period. The generic name is derived from the name of the locality in which the holotype was found (Udan Sayr) and Greek ''ceras/κέρας'' meaning "horn" and ''-ops/ωψ'' meaning "face". ''Udanoceratops'' is best known from the holotype specimen, which represents a large individual comprising a large, relatively well-preserved and almost complete skull, and sparse body remains including vertebrae.

1992 In Paleontology
Plants Cycads Conifers Angiosperms Arthropods Insects Archosauromorphs * During the 1992 field season a concerted effort was undertaken by the Royal Tyrell Museum to recover the remains of young hadrosaurs. The researchers describe the acquisition that season of 43 specimens as being a success. Most of the recovered fossils were of dentaries missing their teeth, bones from limbs and feet, as well as vertebral centra. * Jack Horner speculated that transitional species evolved in the uppermost part of the Two Medicine Formation during the Bearpaw Transgression. This was during a half-million year span as the transgression inundated the Judith River Formation and, later, the Two Medicine area, gradually destroying the local dinosaurs' preferred habitats. Horner cited certain ceratopsid and pachycephalosaurid species as possible evidence for his hypothesis. Newly named non-avian dinosaurs Data courtesy of George Olshevsky's dinosaur genera list.

Djadokhta Formation
The Djadochta Formation (sometimes transcribed and also known as Djadokhta, Djadokata, or Dzhadokhtskaya) is a highly fossiliferous geological formation situated in Central Asia, Gobi Desert, dating from the Late Cretaceous period, about 75 million to 71 million years ago. The type locality is the Bayn Dzak locality, famously known as the Flaming Cliffs. Dinosaur, mammal, and other reptile remains are among the fossils that have been recovered from the formation. Excavation history The Djadochta Formation was first documented and explored—though only a single locality—during paleontological expeditions of the American Museum of Natural History in 1922–1925, which were part of the Central Asiatic Expeditions. The expeditions were led by Roy Chapman Andrews, in company of Walter Willis Granger as chief paleontologist and field team. The team did extensive exploration at the Bayn Dzak (formerly Shabarakh Usu) region, which they nicknamed Flaming Cliffs given that at sunset th ...

Leptoceratopsid
Leptoceratopsidae is an extinct family of neoceratopsian dinosaurs from Asia, North America and Europe. Leptoceratopsids resembled, and were closely related to, other neoceratopsians, such as the families Protoceratopsidae and Ceratopsidae, but they were more primitive and generally smaller. Phylogeny Leptoceratopsidae was originally named by Franz Nopcsa von Felső-Szilvás in 1923 as a subfamily Leptoceratopsinae, and its type species is ''Leptoceratops gracilis''. Mackovicky, in 2001, defined it as a stem-based taxon and a family consisting of ''Leptoceratops gracilis'' and all species closer to ''Leptoceratops'' than to ''Triceratops horridus''.Makovicky, P.J. 2001.

Barun Goyot Formation
The Barun Goyot Formation (also known as Baruungoyot Formation or West Goyot Formation) 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 Barun Goyot 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 Barun Goyot 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 Barun Goyot Formation. It is approximately in thickness,Gradzinski, R.; & Jerzykiewicz, T. (1974).

Bayan Mandahu Formation
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 ...

Protoceratops Hellenikorhinus
''Protoceratops'' (; ) is a genus of small protoceratopsid dinosaurs that lived in Asia during the Late Cretaceous, around 75 to 71 million years ago. The genus ''Protoceratops'' includes two species: ''P. andrewsi'' and the larger ''P. hellenikorhinus''. The former was described in 1923 with fossils from the Mongolian Djadokhta Formation, and the latter in 2001 with fossils from the Chinese Bayan Mandahu Formation. ''Protoceratops'' was initially believed to be an ancestor of ankylosaurians and larger ceratopsians, such as ''Triceratops'' and relatives, until the discoveries of other protoceratopsids. Populations of ''P. andrewsi'' may have evolved into '' Bagaceratops'' through anagenesis. ''Protoceratops'' were small ceratopsians, about long and in body mass. While adults were largely quadrupedal, juveniles had the capacity to walk around bipedally if necessary. They were characterized by a proportionally large skull, short and stiff neck, and neck frill. The frill was lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
