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 ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eusuchia
Eusuchia is a clade of crocodylomorphs that first appeared in the Early Cretaceous with ''Hylaeochampsa''. Along with Dyrosauridae and Sebecosuchia, they were the only crocodyliformes who survived the K-T extinction. Since the other two clades died out 47 and 11 million years ago respectively, all living crocodilian species are eusuchians, as are many extinct forms. Definition Eusuchia was originally defined by Thomas Henry Huxley in 1875 as an apomorphy-based group, meaning that it was defined by shared characteristics rather than relations. These characteristics include pterygoid-bounded choanae and vertebrae which are procoelous (concave from the front and convex from the back). The possibility that these traits may have been convergently evolved in different groups of neosuchians rather than one lineage spurred some modern paleontologists to revise the group's definition to make it defined solely by relations. In 1999, Christopher Brochu redefined Eusuchia as "the last common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Crocodyliformes
Crocodyliformes is a clade of crurotarsan archosaurs, the group often traditionally referred to as "crocodilians". They are the first members of Crocodylomorpha to possess many of the features that define later relatives. They are the only pseudosuchians to survive the K-Pg extinction event. In 1988, Michael J. Benton and James M. Clark argued that all traditional names for well-known groups of animals should be restricted to their crown clades, that is, used only for natural groups comprising all living members of any given lineage. This posed a problem for the crocodilians, because the name Crocodylia, while used in various ways by various scientists, had always included not only living crocodilians but many of their extinct ancestors known only from the fossil record.Benton, M.J. and Clark, J.M.

Squamata
Squamata (, Latin ''squamatus'', 'scaly, having scales') is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the dwarf gecko (''Sphaerodactylus ariasae'') to the Reticulated python (''Malayopython reticulatus'') and the now-extinct mosasaurs, which reached lengths over . Among other reptiles, squamates are most close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry 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 Su ...

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 ...

Ferdinand Stoliczka
Ferdinand Stoliczka (Czech written Stolička, 7 June 1838 – 19 June 1874) was a Moravian palaeontologist who worked in India on paleontology, geology and various aspects of zoology, including ornithology, malacology, and herpetology. He died of high altitude sickness in Murgo during an expedition across the Himalayas. Early life Stoliczka was born at the lodge ''Zámeček'' near Kroměříž in Moravia. Stoliczka, whose father was a forester who took care of the estate of the Archbishop of Olomouc, studied at a German Secondary school in Kroměříž. Although Stoliczka published 79 articles from 1859–1875, he never wrote anything in Czech. It is believed that he spoke German at home. In his Calcutta years he was an important figure in the German-speaking community there. Stoliczka studied geology and palaeontology at Prague and the University of Vienna under Professor Eduard Suess and Dr Rudolf Hoernes. He graduated with a Ph D from the University of Tübingen on 14 November ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winzendorf-Muthmannsdorf
The market town of Winzendorf-Muthmannsdorf is an Austrian municipality in the district of Wiener Neustadt-Land in Lower Austria. It is situated some 64 km south of Vienna at the edge of the Southern Viennese Basin. Geography Winzendorf-Muthmannsdorf is situated in Lower Austria's industrial zone (Industrieviertel) on the edge of the Steinfeld, also called the Dry Plain, the southern region of the Vienna Basin. The area of the market town covers 16.16 square kilometres. 53.93 percent of the area is forested. The Fischauer Vorberge with an altitude of up to about 600 m run through the municipal area. Characteristic of these hills are the pine forests with black pine the typical ''Wienerwald-Schwarzföhren'' (the ''austriaca'' form of the European Black Pine, ''Pinus nigra''). The southern part of the municipality, the cadastral municipality of Winzendorf is situated on the Steinfeld, the northern part, Muthmannsdorf, in a valley basin called "Neue Welt" (New World).

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
