Doratodon
''Doratodon'' is an extinct genus of Late Cretaceous ziphodont crocodylomorph that was once believed to be a dinosaur,Company, J., Suberbiola, X.P., Ruiz-Omeñaca, J.I. & Buscalioni, A.D. (2005). A new species of ''Doratodon'' (Crocodyliformes: Ziphosuchia) from the Late Cretaceous of Spain. ''Journal of Vertebrate Paleontology'' 25(2): 343–353 that could be a sebecosuchian mesoeucrocodylian. Two species of ''Doratodon'' are known to science: ''D. carcharidens'' from Austria (Grünbach Formation) and Hungary (Csehbánya Formation), the type species; and ''D. ibericus'' from Spain (Sierra Perenchiza Formation). The holotype of ''D. carcharidens'' consists of a denture and a mandible.Zoltan Csiki-Sava, Eric Buffetaut, Attila Ősi, Xabier Pereda-Suberbiola, Stephen L.

Emanuel Bunzel
Emanuel Bunzel (1828–1895), was an Austrian paleontologist. Biography Emanuel Bunzel was born in Prague, Kingdom of Bohemia (today the Czech Republic), in 1828. In 1871, he described a skull fragment found in an Austrian coal mine in 1859 by colleagues Ferdinand Stoliczka and Eduard Suess as the type specimen for the dinosaur genus '' Struthiosaurus'', the first discovered in the region. Another dinosaur he described initially as a species of ''Iguanodon'' (''I. suessii'') has since been reassigned to the genus ''Mochlodon'', also found in 1859 alongside ''Struthiosaurus''. Also in 1871, he named the crocodylomorph '' Crocodilus carcharidens'' (now ''Doratodon''), the pterosaur ''"Ornithocheirus''" '' buenzeli'' and the theropod dinosaur ''Megalosaurus schnaitheimi'', now believed to have been based upon remains referable to the metriorhynchid crocodylomorph ''Dakosaurus maximus ''Dakosaurus'' is an extinct genus of crocodylomorph within the family Metriorhynchidae that l ...

Ziphosuchia
Ziphosuchia is a clade of mesoeucrocodylian crocodyliforms that includes notosuchians and sebecosuchians. Systematics First constructed in 2000, it was considered to include ''Notosuchus'', ''Libycosuchus'', and Sebecosuchia. In a 2004 phylogenetic study, it was defined as the most recent common ancestor of ''Notosuchus'', ''Libycosuchus'', and Baurusuchoidea and all of its descendants. Ziphosuchia is often considered to be the sister group of Neosuchia, a clade that includes modern crocodilians. ''Razanandrongobe ''Razanandrongobe'' (meaning "ancestor f thelarge lizard" in Malagasy) is a genus of carnivorous ziphosuchian crocodyliform from the Middle Jurassic of Madagascar.

Sebecosuchia
Sebecosuchia is an extinct group of mesoeucrocodylian crocodyliforms that includes the families Sebecidae and Baurusuchidae. The group was long thought to have first appeared in the Late Cretaceous with the baurusuchids and become extinct in the Miocene with the last sebecids, but ''Razanandrongobe'' pushes the origin of Sebecosuchia to the Middle Jurassic. Fossils have been found primarily from South America but have also been found in Europe, North Africa, Madagascar, and the Indian subcontinent. History and phylogeny Sebecosuchia was first constructed in 1937 by George Gaylord Simpson.Simpson, G.G. 1937. "New reptiles from the Eocene of South America". ''American Museum Novitates'' 967: 1-20 In 1946 the concept was again used by American paleontologist Edwin Colbert to include ''Sebecus'' and Baurusuchidae. ''Sebecus'', which had been known from South America since 1937, was an unusual crocodyliform with a deep snout and teeth that were ziphodont, or serrated and laterally comp ...

Grünbach Formation
The Grünbach Formation is an Austrian geological formation that dates to the lower Campanian age of the Late Cretaceous. it forms part of the Gosau Group, and represents a marine regression event, representing a coastal/brackish environment, being underlain by the marine carbonate Maiersdorf Formation and overlain by the deep marine siliciclastic Piesting Formation. The main lithology is clay, marl, siltstone and sandstone, with a minor conglomerate component. Coal seams have also been noted. It is notable for its fossils including those of dinosaurs and plants. Vertebrate paleofauna All remains have been found at a single locality, which is a thin marl seam in the Konstantin mining tunnel, within the Felbering Mine in the Neue Welt area north west of Muthmannsdorf in Lower Austria. The initial remains were discovered in 1859 after an ornithopod tooth was found in a piece of coal in a dump outside the mine by Professor Ferdinand Stoliczka, and the productive seam discovered ...

Csehbánya Formation
The Csehbánya Formation is a Formation (geology), geological formation in the Transdanubian Mountains of Veszprém County, Hungary. The formation dates to the Late Santonian (around 85-84 million years ago) of the Late Cretaceous. It represents a floodplain environment as opposed to the swampy lacustrine environment of the simultaneous Ajka Coal Formation, though there is complete overlap in terms of fauna. It underlies the Jákó Marl Formation, and laterally transitions to the Ajka Coal Formation. Geology The lithology of the unit is a cyclic variation of conglomerate, sandstone, variegated siltstone, clay and marl layers with some sporadic thin coal seams. It is unconformably overlies the Late Triassic Main Dolomite Formation, which has deposits of the Late Cretaceous, Upper Cretaceous Nagytárkány Bauxite Formation within deep karstic sinkholes in the formation. There is a basal conglomerate of dolomite clasts at the base of the Csehbánya formation. The main exposed port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhadinosaurus
''Rhadinosaurus'' (meaning "slender lizard") is a genus of nodosaurid ankylosaur first described in 1881 by Harry Govier Seeley, based on remains uncovered in Austria sometime between 1859 and 1870 by Edward Suess and Pawlowitsch. It was a herbivore that lived around 84.9 to 70.6 million years ago (during the Late Cretaceous period). The type species is ''R. alcimus''. Fossils The ''Rhadinosaurus'' hypodigm (holotype) consists of one tibia fragment, one limb fragment, two fibulae, and two dorsal vertebrae. The fibulae (PIUW 2349/34), which are clearly ankylosaurian, were originally identified as femora in the original description, but were eventually re-identified in a 2001 review of ankylosaur specimens from the Grünbach Formation.X.

Holotype
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 "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theropod
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago ( Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a characteri ...

Ankylosauria
Ankylosauria is a group of herbivorous dinosaurs of the order Ornithischia. It includes the great majority of dinosaurs with armor in the form of bony osteoderms, similar to turtles. Ankylosaurs were bulky quadrupeds, with short, powerful limbs. They are known to have first appeared in the Middle Jurassic, and persisted until the end of the Cretaceous Period. The two main families of Ankylosaurs, Nodosauridae and Ankylosauridae are primarily known from the Northern Hemisphere, but the more basal Parankylosauria are known from southern Gondwana during the Cretaceous. Ankylosauria was first named by Henry Fairfield Osborn in 1923.Osborn, H. F. (1923). "Two Lower Cretaceous dinosaurs of Mongolia." ''American Museum Novitates'', 95: 1–1/ref> In the Linnaean classification system, the group is usually considered either a suborder or an infraorder. It is contained within the group Thyreophora, which also includes the stegosaurs, armored dinosaurs known for their combination of plate ...

Gosau Formation
The Gosau Group (German: ''Gosau-Gruppe'') is a geological stratigraphic group in Austria, Germany and western Slovakia whose strata date back to the Late Cretaceous to Eocene.Höfling, 1985McCann, 2008 It is exposed in numerous sporadic isolated basins within the Northern Calcareous Alps. It is divided into two subgroups, the Lower Gosau Subgroup which dates from the Turonian to Campanian, approximately 90 to 75 Ma and the Upper Gosau Subgroup which dates to the Santonian to Eocene, about 83.5 to 50 Ma. The formations within each subunit vary significantly between basins. The sequence is largely marine, but the Grünbach Formation represents a terrestrial deposit. Many of the units of the group are fossiliferous, typically providing marine fossils such as ammonites, though terrestrial remains including those of dinosaurs are known from the Grünbach Formation and Schönleiten Formation. Fossil content Among others, the following fossils have been described from the Gosau Group: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry Govier Seeley
Harry Govier Seeley (18 February 1839 – 8 January 1909) was a British paleontologist. Early life Seeley was born in London on 18 February 1839, the second son of Richard Hovill Seeley, a goldsmith, and his second wife Mary Govier. When his father was declared bankrupt, Seeley was sent to live with a family of piano makers. Between the ages of eleven and fourteen, he went to a day school and then spent the next two years learning to make pianos. He also attended lectures at the Royal School of Mines by Thomas Henry Huxley, Edward Forbes, and other notable scientists. In 1855, with the support of his uncle, Seeley began to study law but shortly gave it up to pursue a career as an actuary. In the late 1850s, he studied English and mathematics at the Working Men's College and served as a secretary for the college's museum. He also worked in the library of the British Museum, where Samuel Pickworth Woodward encouraged him to study geology. In 1859, Seeley began studies at Sidney S ...
