Group (stratigraphy)
In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology, but all were deposited in the same vast ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...

Sinoceratops
''Sinoceratops'' is an extinct genus of ceratopsian dinosaur that lived approximately 73 million years ago during the latter part of the Cretaceous Period in what is now Shandong province in China. It was named in 2010 by Xu Xing ''et al.'' for three skulls from Zhucheng, China. The name of its type species ''Sinoceratops zhuchengensis'' means "Chinese horned face from Zhucheng", after the location of its discovery. ''Sinoceratops'' was a medium-sized, averagely-built, ground-dwelling, quadrupedal herbivore. It could grow up to an estimated in length and weigh up to . It was the first ceratopsid dinosaur discovered in China, and the only ceratopsid known from Asia. All other centrosaurines, and all chasmosaurines, are known from fossils discovered in North America, except for possibly ''Turanoceratops''. ''Sinoceratops'' is also significant because it is one of the largest known centrosaurines, and is much larger than any other known basal members of this group. ''Sinocerato ...

Shantungosaurus Life
''Shantungosaurus'' (meaning "''Shandong Lizard''") is a genus of very large saurolophine hadrosaurid dinosaur found in the Late Cretaceous Wangshi Group of the Shandong Peninsula in China, containing a single species, ''Shantungosaurus giganteus''. The stratigraphic interval of ''Shantungosaurus'' ranges from the top of the Xingezhuang Formation to the middle of the Hongtuya Formation, middle to late Campanian in age. ''Shantungosaurus'' is so far the largest hadrosauroid taxon in the world, reaching between to in length and to in body mass. History of discovery First described in 1973, ''Shantungosaurus'' is known from over five incomplete skeletons. Chinese scientist Xing Xu and his colleagues indicate that ''Shantungosaurus'' is very similar to and shares many unique characters with ''Edmontosaurus'', forming a node of an ''Edmontosaurus''–''Shantungosaurus'' clade between North America and Asia, based on the new materials recovered in Shandong.

Pinacosaurus Jack Wood 2017
''Pinacosaurus'' (meaning "Plank lizard") is a genus of ankylosaurid thyreophoran dinosaur that lived in Asia during the Late Cretaceous (Santonian-Campanian, roughly 75 million to 71 million years ago), mainly in Mongolia and China. The first remains of the genus were found in 1923, and the type species ''Pinacosaurus grangeri'' was named in 1933. ''Pinacosaurus mephistocephalus'' named in 1999, is a second possibly valid species differing from the type species in details of the skull armour. Of ''Pinacosaurus grangeri'' many skeletons have been found, more than of any other ankylosaur. These predominantly consist of juveniles that perhaps lived in herds roaming the desert landscape of their habitat. ''Pinacosaurus'' was a medium-sized ankylosaurine, about five metres long and weighed up to two tonnes. Its body was flat and low-slung but not as heavily built as in some other members of the Ankylosaurinae. The head was protected by bone tiles, hence its name. Each nostril was for ...

Laiyangosaurus
''Laiyangosaurus'' ("Laiyang lizard") is a genus of saurolophine hadrosaurid from the Late Cretaceous of China. It is known from one species, ''L.youngi'', found in the Laiyang Basin within the province of Shandong. Classification ''Laiyangosaurus'' is a member of the saurolophine tribe Edmontosaurini. A number of specimens referred to ''Laiyangosaurus'' (IVPP V23405.1, V23403.1, V23402.1, V23404, V23402.7) apparently belong to kritosaurin and lambeosaurine hadrosaurids.Zhang, Yu-Guang; Wang, Ke-Bai; Chen, Shu-Qing; Liu, Di; Xing, Hai (2019).

Ischioceratops
''Ischioceratops'' () is an extinct genus of small herbivorous ceratopsian dinosaur that lived approximately 69 million years ago during the latter part of the Cretaceous Period in what is now China. ''Ischioceratops'' was a small sized, moderately-built, ground-dwelling, quadrupedal herbivore, whose total body length has been estimated to be about . The ceratopsians were a group of dinosaurs with parrot-like beaks which fed on vegetation and thrived in North America and Asia during the Cretaceous Period, which ended approximately 66 million years ago, at which point they all became extinct. Its name means "ischium horned face", referring to the peculiar shape of the ischiatic bones. ''Ischioceratops'' existed in the Wangshi Group during the late Cretaceous. It lived alongside centrosaurines, saurolophines, and tyrannosaurines. The most common creatures in the formation were ''Sinoceratops'' and ''Zhuchengtyrannus''.

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ...

Chingkankousaurus
''Chingkankousaurus'' (named for Ch'ing-kang-kou, ''sic'' for Wade–Giles ''Chin''1''-kang''1''-k'ou''3, pinyin ''Jin-gang-kou'' 'diamond port' village) is a genus of theropod dinosaur containing the single species ''Chingkankousaurus fragilis''. ''C. fragilis'' is known only from a single fossilized bone fragment (specimen number IVPP V636) from the late Cretaceous Period Wangshi Series of Shandong province in eastern China. Description ''Chingkankousaurus'' was identified by Yang Zhongjian (C.C. Young) in 1958 from a single "scapula", which he said "basically resembles that of ''Allosaurus'' but is smaller." It had been proposed that the scapula was a rib or gastralia fragment, but this was considered unlikely in a 2013 study. Molnar et al. (1990) thought the scapula may have belonged to a tyrannosaurid. Chure (2001) assigned it to the Coelurosauria, and more recent research has supported the initial identification as a type of tyrannosauroid, with some even arguing it to be a ...
