Barsboldia Sicinskii (2)
''Barsboldia'' (meaning "of Barsbold", a well-known Mongolian paleontologist) is a genus of large hadrosaurid dinosaur from the early Maastrichtian Nemegt Formation of Ömnogöv', Mongolia. It is known from a partial vertebral column, partial pelvis, and some ribs. Discovery In 1970, a Polish-Mongolian expedition near the Nemegt found the skeleton of an ornithopod and first assigned it to '' Saurolophus angustirostris''. However, two Polish paleontologists, Teresa Maryańska and Halszka Osmólska, came to the conclusion that it was a lambeosaurine that had to represent a separate species. They named and described ''Barsboldia sicinskii'' based on the holotype specimen ZPAL MgD-1/110. The genus name honors the Mongolian paleontologist Rinchen Barsbold, while the species name honors Wojciech Siciński, the technician at the Warsaw Paleobiological Institute who prepared the skeleton. The holotype specimen, found in a layer of the Nemegt Formation dating to the early Maastrich ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.

Honghesaurus
''Honghesaurus'' is an extinct genus of pachypleurosaur from the Anisian-age Guanling Formation of China. The type specimen measures about in total body length. Classification The cladogram below follows Xu and colleagues (2022), when they used ''Youngina'' as a reference point for rooting the tree. Using a selection of placodont Placodonts (" Tablet teeth") are an extinct order of marine reptiles that lived during the Triassic period, becoming extinct at the end of the period. They were part of Sauropterygia, the group that includes plesiosaurs. Placodonts were genera ...s resulted in a less resolved topology.

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] |
Garudimimus
''Garudimimus'' (meaning "Garuda mimic") is a genus of ornithomimosaur that lived in Asia during the Late Cretaceous. The genus is known from a single specimen found in 1981 by a Soviet-Mongolian paleontological expedition in the Bayan Shireh Formation and formally described in the same year by Rinchen Barsbold; the only species is ''Garudimimus brevipes''. Several interpretations about the anatomical traits of ''Garudimimus'' were made in posterior examinations of the specimen, but most of them were criticized during its comprehensive redescription in 2005. Extensive undescribed ornithomimosaur remains at the type locality of ''Garudimimus'' may represent additional specimens of the genus. The only known specimen of ''Garudimimus'' was a medium-sized animal measuring nearly in length and weighing about . It was an ornithomimosaur with a mix of basal and derived features; unlike primitive ornithomimosaurs, both upper and lower jaws were toothless, a trait that is often reporte ...

Lambeosaurinae
Lambeosaurinae is a group of crested hadrosaurid dinosaurs. Classification Lambeosaurines have been traditionally split into the tribes or clades Parasaurolophini (''Parasaurolophus'', ''Charonosaurus'', others (?).) and Lambeosaurini (''Corythosaurus'', ''Hypacrosaurus'', ''Lambeosaurus'', others.). Corythosaurini (synonym of Lambeosaurini, see below) and Parasaurolophini as terms entered the formal literature in Evans and Reisz's 2007 redescription of ''Lambeosaurus magnicristatus''. Corythosaurini was defined as all taxa more closely related to ''Corythosaurus casuarius'' than to ''Parasaurolophus walkeri'', and Parasaurolophini as all those taxa closer to ''P. walkeri'' than to ''C. casuarius''. In this study, ''Charonosaurus'' and ''Parasaurolophus'' are parasaurolophins, and ''Corythosaurus'', ''Hypacrosaurus'', ''Lambeosaurus'', ''Nipponosaurus'', and ''Olorotitan'' are corythosaurins. However, later researchers pointed out that due to the rules of priority set forth b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halszka Osmólska
Halszka Osmólska (September 15, 1930 – March 31, 2008) was a Polish paleontologist who had specialized in Mongolian dinosaurs. Biography She was born in 1930 in Poznań. In 1949, she began to study biology at Faculty of Biology and Earth Sciences of the University of Poznań before moving to Warsaw and studying at the Warsaw University, which she graduated from in 1955. Since then she worked at the Institute of Paleobiology of the Polish Academy of Sciences (PAN). Between 1983–1988, she served as the institute's director. She was a member of the Polish–Mongolian expeditions to the Gobi Desert (1963–1965 and 1967–1971) and she described many finds from these rocks, often with Teresa Maryańska. Among the dinosaurs she described are: * ''Elmisaurus'' (and Elmisauridae) (1981), ''Hulsanpes'' (1982), '' Borogovia'' (1987), and ''Bagaraatan'' (1996) * with Maryańska, ''Homalocephale'', ''Prenocephale'', and ''Tylocephale'' (and Pachycephalosauria)(1974), ''Bagaceratops'' ...

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).

Muttaburrasaurus NT
''Muttaburrasaurus'' was a genus of herbivorous iguanodontian ornithopod dinosaur, which lived in what is now northeastern Australia sometime between 110 and 103 million years agoHoltz, Thomas R. Jr. (2012) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2011 Appendix./ref> during the early Cretaceous period. It has been recovered in some analyses as a member of the iguanodontian clade Rhabdodontomorpha. After ''Kunbarrasaurus'', it is Australia's most completely known dinosaur from skeletal remains. It was named after Muttaburra, the site in Queensland, Australia, where it was found. Description ''Muttaburrasaurus'' was about and weighed around . The femur of the holotype has a length of . Whether ''Muttaburrasaurus'' is capable of quadrupedal movement has been debated; it was originally thought to be an "iguanodontid"; thought recent studies indicate a rhabdodont position.
