Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob ...

Town (China)
When referring to political divisions of China, town is the standard English translation of the Chinese (traditional: ; ). The Constitution of the People's Republic of China classifies towns as third-level administrative units, along with for example townships (). A township is typically smaller in population and more remote than a town. Similarly to a higher-level administrative units, the borders of a town would typically include an urban core (a small town with the population on the order of 10,000 people), as well as rural area with some villages (, or ). Map representation A typical provincial map would merely show a town as a circle centered at its urban area and labeled with its name, while a more detailed one (e.g., a map of a single county-level division) would also show the borders dividing the county or county-level city into towns () and/or township () and subdistrict (街道) units. The town in which the county level government, and usually the division's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dsungaripterus
''Dsungaripterus'' is a genus of dsungaripterid pterosaur with an average wingspan of . ''Dsungaripterus'' lived during the Early Cretaceous in what is now China, and its first fossil was found in the Junggar Basin. Description ''Dsungaripterus weii'' had a wing span of . Like most dsungaripteroids it had a rather robust skeleton with thick walls and stouty bodily proportions, suggesting a mostly terrestrial lifestyle. The flight style of these animals is unclear, but it was probably punctuated by abrupt landings and extensive flapping. The skull of ''Dsungaripterus'', long, bore a low bone crest that ran down from the base of the skull to halfway to the beak. ''Dsungaripteruss head and neck were together almost long. Its most notable feature are its long, narrow, upcurved jaws with a pointed tip. It had no teeth in the front part of its jaws, which were probably used to remove prey from cracks in rocks and/or the sandy, muddy inland environments it inhabited. It had knobbl ...

Lonchognathosaurus
''Lonchognathosaurus'' is a genus of dsungaripterid pterodactyloid pterosaur from the Albian-age Lower Cretaceous Lianmuqin Formation of Xinjiang, China. The genus was named in 2004 by Michael Maisch, Andreas Matzke and Sun Ge. The type species is ''Lonchognathosaurus acutirostris''. The genus name is derived from Greek , "lance", , "jaw" and , "lizard", in reference to the fact that it is a reptile with pointed jaws. The specific name means "needle snout" in Latin. ''Lonchognathosaurus'' is based on holotype SGP 2001/19, found near Urumqi in the southern Junggar Basin, the front portion of a skull and lower jaws that came from a large individual; the estimated length of the complete skull was about 400 mm (15.75 in). The point of the upper jaw, composed of the premaxilla bones, was slender and had a needle-like tip. The teeth of the upper jaw appeared far back of the tip, and were well-spaced, diminishing in size from front to back; they ended again in front of t ...

Dsungaripteridae
Dsungaripteridae is a group of pterosaurs within the suborder Pterodactyloidea. They were robust pterosaurs with good terrestrial abilities and flight honed for inland settings. Classification In 1964 Young created a family to place the recently found Chinese genus '' Dsungaripterus''. Later on, also '' Noripterus'' (then now with the name " Phobetor" which was already occupied, therefore the quotation marks) were assigned to the family. In 2003, Alexander Kellner gave the exact definition as a clade:Kellner, A.W.A., 2003. Pterosaur phylogeny and comments on the evolutionary history of the AN group. In: Buffetaut, E., Mazin, J.M. (Eds.), ''Evolution and Palaeobiology of Pterosaurs. Geological Society, London, Special Publication'' 217, 105–137. the group was composed out of the latest common ancestor of ''Dsungaripterus'', ''Noripterus'' and “Phobetor”, and all its descendants. As synapomorphies he gave the next six characteristics: a relatively small eye-socket, which is p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wuerhosaurus Sketch2
''Wuerhosaurus'' is a genus of stegosaurid dinosaur from the Early Cretaceous Period of western China and Inner Mongolia. As such, it was one of the last genera of stegosaurians known to have existed, since most others lived in the late Jurassic. Discovery and species ''Wuerhosaurus homheni'' is the type species, described by Dong Zhiming in 1973 from the Tugulu Group in Xinjiang, western China. The generic name is derived from the city of Wuerho. Three separate localities in the Wuerho Valley were discovered to contain material from the new stegosaur: , 64043 and 64045. The remains consisted of the holotype, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) V.4006, a skull-less fragmentary skeleton, and the paratype IVPP V.4007. Holotype material includes a mostly complete pelvis and sacrum lacking the ischium, the first caudal vertebrae, two dorsal vertebrae, a scapulocoracoid, humerus and phalanx, as well as two dermal plates. Three posterior caudal vertebra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tugulusaurus
''Tugulusaurus'' (meaning "Tugulu lizard") is a genus of coelurosaurian theropod dinosaur that belongs to the Alvarezsauroidea. It is known from the Early Cretaceous Tugulu Group in the Urhe area of the People's Republic of China. It was one of the first members of Alvarezsauria ever discovered. Discovery From 1964 dinosaur fossils were excavated in the Junggar Basin of Xinjiang. In 1973 a number of these were described by paleontologist Dong Zhiming, among them the bones of a small theropod which he named ''Tugulusaurus faciles''. The generic name refers to the Tugulu Group. The specific name is derived from Latin ''facilis'', here with the meaning of "easily moving", referring to the agility of the animal as indicated by its "delicate bones". The holotype, IVPP V4025, was found in layers of the Lianmuqin Formation dating from the Barremian–Albian. It consists of a partial skeleton including four partial tail vertebrae, much of the left leg and part of the right, the first ...

Psittacosaurus
''Psittacosaurus'' ( ; "parrot lizard") is a genus of extinct ceratopsian dinosaur from the Early Cretaceous of what is now Asia, existing between 126 and 101 million years ago. It is notable for being the most species-rich non-avian dinosaur genus. Up to 12 species are known, from across China, Mongolia, Russia, and Thailand. The species of ''Psittacosaurus'' were obligate bipeds at adulthood, with a high skull and a robust beak. One individual was found preserved with long filaments on the tail, similar to those of ''Tianyulong''. ''Psittacosaurus'' probably had complex behaviours, based on the proportions and relative size of the brain. It may have been active for short periods of time during the day and night, and had well-developed senses of smell and vision. ''Psittacosaurus'' was one of the earliest ceratopsians, but closer to ''Triceratops'' than ''Yinlong''. Once in its own family, Psittacosauridae, with other genera like ''Hongshanosaurus'', it is now considered to be s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phaedrolosaurus
''Phaedrolosaurus'' is a genus of theropod dinosaur, based on a single tooth possibly from the Valanginian-Albian-age Lower Cretaceous Lianmugin Formation of Wuerho, Xinjiang, People's Republic of China, China. Discovery and naming The first known remains of ''Phaedrolosaurus'' were discovered in China during an Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) expedition to China's Wuerho area in 1964. The tooth, IVPP V , was in 1973 described and named by Dong Zhiming as a new genus and species. The type species is ''Phaedrolosaurus ilikensis''. The generic name is derived from the Greek φαιδρός, ''phaidros'', "elated", referring to the agility of the animal. The specific name (zoology), specific name refers to the Ilike Formation. Dong stated the thirty-one millimetre long tooth was like those of ''Deinonychus'', albeit thicker, shorter, and more solid. He regarded the new genus as a possible dromaeosauridae, dromaeosaurid.Z.-M. Dong. (1973). [Dinosaurs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xinjiangovenator
''Xinjiangovenator'' (meaning "Xinjiang hunter") is a genus of coelurosaurian dinosaur, dinosaurs, possibly part of the group Maniraptora, which lived during the Early Cretaceous Period (geology), period, sometime between the Valanginian and Albian stages. The remains of ''Xinjiangovenator'' were found in the Lianmuqin Formation of Wuerho, Xinjiang, China, and were first described by Dong Zhiming in 1973. The genus is based on a single specimen, an articulated partial right lower leg, containing the tibia, three pieces of the fibula, the calcaneum and the astragalus. This specimen, Institute of Vertebrate Paleontology and Paleoanthropology, IVPP V4024-2, is the holotype of the genus. The holotype was originally thought to be another specimen of ''Phaedrolosaurus''. However, ''Phaedrolosaurus'' is based only on a non-diagnostic tooth, so the hindlimb bones were given their own genus by Oliver Rauhut and Xu Xing (paleontologist), Xu Xing in 2005.
