Rinchen Barsbold
, Rinchyengiin Barsbold, born December 21, 1935 in Ulaanbaatar) is a Mongolian paleontologist and geologist. He works with the Institute of Geology, at Ulaanbaatar, Mongolia. He is an expert in vertebrate paleontology and Mesozoic stratigraphy. Barsbold has been instrumental in the discovery and recovery of one of the largest dinosaur collections in the world. His work has helped to form a more modern understanding of the later stages of dinosaur evolution in Eurasia. Barsbold has had considerable influence on dinosaur paleontology in the Communist world. His scientific work has made him a leading authority on theropods of the Gobi Desert, starting with his doctoral dissertation on these dinosaurs. As early as 1983, he noted that in different lineages of theropods, many features previously only known from birds had evolved in various combinations (Barsbold 1983). He postulated that as a result of this "ornithization", one or several lineages of theropods that happened to acquire th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulaanbaatar
Ulaanbaatar (; mn, Улаанбаатар, , "Red Hero"), previously anglicized as Ulan Bator, is the capital and most populous city of Mongolia. It is the coldest capital city in the world, on average. The municipality is located in north central Mongolia at an elevation of about in a valley on the Tuul River. The city was originally founded in 1639 as a nomadic Buddhist monastic center, changing location 28 times, and was permanently settled at its current location in 1778. During its early years, as Örgöö (anglicized as Urga), it became Mongolia's preeminent religious center and seat of the Jebtsundamba Khutuktu, the spiritual head of the Gelug lineage of Tibetan Buddhism in Mongolia. Following the regulation of Qing-Russian trade by the Treaty of Kyakhta in 1727, a caravan route between Beijing and Kyakhta opened up, along which the city was eventually settled. With the collapse of the Qing Empire in 1911, the city was a focal point for independence efforts, lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallimimus
''Gallimimus'' ( ) is a genus of Theropoda, theropod dinosaur that lived in what is now Mongolia during the Late Cretaceous Period (geology), period, about seventy mya (unit), million years ago (mya). Several fossils in various stages of growth were discovered by Polish-Mongolian expeditions in the Gobi Desert of Mongolia during the 1960s; a large skeleton discovered in this region was made the holotype specimen of the new genus and species ''Gallimimus bullatus'' in 1972. The generic name means "chicken mimic", referring to the similarities between its neck vertebrae and those of the Galliformes. The specific name is derived from ''Bulla (amulet), bulla'', a golden capsule worn by Ancient Rome, Roman youth, in reference to a bulbous structure at the base of the skull of ''Gallimimus''. At the time it was named, the fossils of ''Gallimimus'' represented the most complete and best preserved ornithomimid ("ostrich dinosaur") material yet discovered, and the genus remains one of the ...

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 ...

Conchoraptor
''Conchoraptor'' (meaning "conch plunderer") is a genus of oviraptorid dinosaurs that lived in Asia during the Late Cretaceous epoch, about 70 million years ago. It is known from the Barun Goyot and Nemegt formations of Mongolia. Discovery When first discovered in the Red Beds of Hermiin Tsav of the Early Maastrichtian Nemegt Formation by a Polish-Mongolian expedition in 1971, scientists believed that ''Conchoraptor'' was a juvenile ''Oviraptor'' and that the animal's missing crest would have begun to grow when the animal reached sexual maturity. Further study of multiple skeletons showed that ''Conchoraptor'' belonged in a new genus. The hands of ''Conchoraptor'' were a major reason that scientists decided to split it off from ''Oviraptor''. Anatomically the hands seemed to be an evolutionary intermediate between those of ''Ajancingenia'' and ''Oviraptor'', making it obvious that this animal was not a member of a known species. The type species of this new genus, ''Conchorap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anserimimus
''Anserimimus'' ( ; "goose mimic") is a genus of ornithomimid theropod dinosaur, from the Late Cretaceous Period of what is now Mongolia. It was a lanky, fast-running animal, possibly an omnivore. From what fossils are known, it probably closely resembled other ornithomimids, except for its more powerful forelimbs. Discovery ''Anserimimus'' was found in the Mongolian aimag, or province, of Bayankhongor during a joint Soviet-Mongolian expedition to the Gobi Desert, in the late 1970s. Mongolian paleontologist Rinchen Barsbold named ''Anserimimus'' in 1988, combining the Latin ''anser'' meaning 'goose' with the Greek ''mimos'' meaning 'mimic'. ''Anser'' is the generic name of several species of geese. Although ''Anserimimus'' does not specifically resemble a goose, ornithomimosaurs have traditionally been named after different types of birds, such as ''Struthiomimus'' ('ostrich mimic'), ''Gallimimus'' ('rooster mimic'), and ''Pelecanimimus'' ('pelican mimic'). The one named specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adasaurus
''Adasaurus'' ( ; meaning "Ada lizard") is a genus of dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous period about 70 million years ago. The genus is known from two partial specimens found in the Nemegt Formation of Mongolia that were partially described in 1983 by the paleontologist Rinchen Barsbold. ''Adasaurus'' was a large dromaeosaurid that was about long weighing . Unlike other dromaeosaurids, ''Adasaurus'' developed a rather small and blunt sickle claw that likely had a reduced use, and a recurved lacrimal bone; this latter trait is also shared with ''Austroraptor''. Though reduced, the sickle claw retained the characteristic rounded articulation of most dromaeosaurids. ''Adasaurus'' was originally regarded as a dromaeosaurine by Barsbold, a group that includes robust dromaeosaurs with deep jaws. Revisions made to the specimens have showed that this dromaeosaurid belongs to the Velociraptorinae which is composed of more lightly built animals like ''V ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Teresa Maryańska
Teresa Maryańska (1937 – 3 October 2019) was a Polish paleontologist who specialized in Mongolian dinosaurs, particularly pachycephalosaurians and ankylosaurians. Peter Dodson (1998 p. 9) states that in 1974 Maryanska together with Halszka Osmólska were among the first "women to describe new kinds of dinosaurs". She is considered not only as one of Poland's but also one of the world's leading experts on dinosaurs. A member of the 1964, 1965, 1970, and 1971 Polish–Mongolian expeditions to the Gobi Desert, she has described many finds from these rocks, often with Halszka Osmólska. Among the dinosaurs she has described are: * '' Saichania'' and '' Tarchia'' (1977) * with Osmólska, '' Homalocephale'', '' Prenocephale'', and '' Tylocephale'' (and Pachycephalosauria) (1974), '' Bagaceratops'' (1975), and '' Barsboldia'' (1981) * and with Osmόlska and Altangerel Perle, '' Goyocephale'' (1982).
