Segnosaurus
''Segnosaurus'' is a genus of therizinosaurid dinosaur that lived in what is now southeastern Mongolia during the Late Cretaceous, about 102–86 million years ago. Multiple incomplete but well-preserved specimens were discovered in the Gobi Desert in the 1970s, and in 1979 the genus and species ''Segnosaurus galbinensis'' were named. The generic name ''Segnosaurus'' means "slow lizard" and the specific name ''galbinensis'' refers to the Galbin region. The known material of this dinosaur includes the lower jaw, neck and tail vertebrae, the pelvis, shoulder girdle, and limb bones. Parts of the specimens have gone missing or become damaged since they were collected. ''Segnosaurus'' was a large-bodied therizinosaur that is estimated to have been about long and to have weighed about . It would have been bipedal, with the trunk of its body tilted upwards. The head was small with a beak at the tip of the jaws, and the neck was long and slender. The lower jaw was down-turned at t ...

Erlikosaurus
''Erlikosaurus'' (meaning "Erlik's lizard") is a genus of therizinosaurid that lived in Asia during the Late Cretaceous period. The fossils, a skull and some post-cranial fragments, were found in the Bayan Shireh Formation of Mongolia in 1972, dating to around 96 million and 89 million years ago. These remains were later described by Altangerel Perle and Rinchen Barsbold in 1980, naming the new genus and species ''Erlikosaurus andrewsi''. It represents the second therizinosaur taxon from this formation (alongside ''Enigmosaurus'' and ''Segnosaurus'') with the most complete skull among members of this peculiar family of dinosaurs. In contrast to most therizinosaurids, ''Erlikosaurus'' was a small member reaching nearly in length and in mass. It had a well-developed beak at the snout tip and toothed jaws that were used for its herbivorous diet. The feet ended in four toes with the first one articulated to the ankle—in contrast to the vestigial first toe of most theropods. Like o ...

Therizinosaur
Therizinosaurs (once called segnosaurs) were large herbivorous Theropoda, theropod dinosaurs whose fossils have been found across the Early Cretaceous, Early to Late Cretaceous deposits in Asia and North America. Various features of the forelimbs, skull and pelvis unite these finds as both theropods and maniraptorans, close relatives to birds. The name of the representative genus, ''Therizinosaurus'', is derived from the Ancient Greek , Greek (, 'to reap' or 'scythe')Translated paper and (, 'lizard'). The older representative, ''Segnosaurus'', is derived from the Latin ('slow') and the Greek . History of research [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enigmosaurus
''Enigmosaurus'' (meaning "Enigma lizard" or "Enigmatic lizard") is a genus of therizinosauroid that lived in Asia during the Late Cretaceous period. It was a medium-sized, ground-dwelling, bipedal herbivore that represents the third therizinosaur taxon from the Bayan Shireh Formation, although it is known from the lower part. The genus is monotypic, including only the type species ''E. mongoliensis'', known from a well preserved pelvis and other tentative body remains. Discovery and naming The holotype, IGM 100/84, was discovered at the Khara Khutul locality in the Bayan Shireh Formation (sometimes called Baynshire Formation or the Baynshirenskaya Svita), southeastern Mongolia, dating from the Late Cretaceous period, and first reported in 1979 on a pelvic comparison with other theropod dinosaurs. At the time, little was known about therizinosaurs. In 1980, it was mentioned again, this time in the new infraorder created by the Mongolian paleontologists Rinchen Barsbold and Altan ...

Bayan Shireh Formation
The Bayan Shireh Formation (also known as Baynshiree/Baynshire, Baynshirenskaya Svita or Baysheen Shireh) is a geological formation in Mongolia, that dates to the Cretaceous period. It was first described and established by Vasiliev et al. 1959. Description The Bayan Shireh Formation is primarily composed by varicoloured claystones and sandstones with calcareous concretions and characterized by grey mudstones and yellowish-brown medium grained sandstones. Up to thick, the most complete sections are found in the eastern Gobi Desert, consisting of fine-grained, often cross-stratified gray sandstone interbedded with claystone and concretionary, intraformational conglomerates with relatively thick units of red to brown mudstone in the upper part. The Baynshire and Burkhant localities are mainly composed by mudstone, siltstone, sandstone, and conglomerates, with most of their sedimentation being fluvial. The environments that were present on the Bayan Shireh Formation consisted ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beipiaosaurus
''Beipiaosaurus'' is a genus of therizinosauroid theropod dinosaurs that lived in Asia during the Early Cretaceous in the Yixian Formation. The first remains were found in 1996 and formally described in 1999. Before the discovery of ''Yutyrannus'', they were among the heaviest dinosaurs known from direct evidence to be feathered. ''Beipiaosaurus'' is known from three reported specimens preserving numerous impressions of feather structures that allowed to determine the feathering color which turned out to be brownish. They were relatively small-sized therizinosaurs, measuring long and weighing about in contrast to the advanced and giant ''Segnosaurus'' or ''Therizinosaurus''. The necks of ''Beipiaosaurus'' were shorter than in most therizinosaurs, whose are characterized by elongated necks adapted for high-browsing. Also, their feet configuration differs from therizinosaurids, having a generic three-toed pes instead of four as seen in other members. The exact classification of ...

Mongolian Academy Of Sciences
The Mongolian Academy of Sciences (, ''Mongol ulsyn Shinjlekh ukhaany Akademi'') is Mongolia's first centre of modern sciences. It came into being in 1921 when the government of newly independent Mongolia issued a resolution declaring the establishment of "The Institute of Literature and Scripts", which was later upgraded into "The Institute of Sciences" and "The Institute of Sciences and Higher Education". In 1961, it was finally reorganized as "The Mongolian Academy of Sciences" MAS. At present there ar14 research institutesantwo affiliated academiesunder MAS. Status The law "on the Legal Status of the Mongolian Academy of Sciences" ratified by the State Great Hural (Parliament) of Mongolia promulgated the Mongolian Academy of Sciences as the central scientific thinktank, whose aim is to develop science and advanced technology in the country. The Mongolian Academy of Sciences is a civil self-governed non-commercial organization. Organization General Assembly of MAS, the Presid ...

Holotype Specimen
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paratype Specimens
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material by the author (th ...
