Burianosaurus
''Burianosaurus'' is an extinct genus of ornithopod dinosaur that lived in what is now the Czech Republic (it was found in 2003 near the city of Kutná Hora), being the first validly named dinosaur from that country. The type species, ''B. augustai'', was named in 2017; the genus name honours the Czech palaeoartist Zdeněk Burian, and the species name honours the Czech palaeontologist Josef Augusta. The holotype specimen is a femur discovered in sediments belonging to the Peruc-Korycany Formation in 2003, which was described as possibly belonging to an iguanodont in 2005. Classification When the fossil was first described in 2005, it was said to be most morphologically similar to Early Cretaceous members of Iguanodontidae, as opposed to later taxa such as ''Rhabdodon''. Madzia ''et al.'' (2017), the study which named the genus, ran two phylogenetic analyses to test the relationships of the taxon. The first, based on the matrix of MacDonald ''et al.'' (2012), found it within th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeoartist
Paleoart (also spelled palaeoart, paleo-art, or paleo art) is any original artistic work that attempts to depict prehistoric life according to scientific evidence. Works of paleoart may be representations of fossil remains or imagined depictions of the living creatures and their ecosystems. While paleoart is typically defined as being scientifically informed, it is often the basis of depictions of prehistoric animals in popular culture, which in turn influences public perception of and fuels interest in these animals. The word paleoart is also used in other informal sense, as a name for prehistoric art, most often cave paintings. Alternative concept of this term is the domain of archeological society. The term "paleoart"–which is a portmanteau of ''paleo'', the Ancient Greek word for "old", and "art"–was introduced in the late 1980s by Mark Hallett for art that depicts subjects related to paleontology, but is considered to have originated as a visual tradition in early 180 ...

Gideonmantellia
''Gideonmantellia'' is an extinct genus of basal ornithopod dinosaur known from the Early Cretaceous (Barremian stage) Camarillas Formation of Galve, Province of Teruel, Spain. It contains a single species, ''Gideonmantellia amosanjuanae''. Discovery and naming In 1982, amateur palaeontologist José María Herrero Marzo together with his son Jesús uncovered in a loam pit near Galve, the ''Poyales Barranco Canales'' site, the remains of a small euornithopod. In 1987 from this material by José Luis Sanz a left femur and ilium were described, which he referred to ''Hypsilophodon foxii''. In 1995 José Ignacio Ruiz-Omeñaca realised the find represented a separate taxon, after he had further prepared the bones in 1994 and 1995. Ruiz-Omeñaca continued his studies from 1996, as part of his thesis. In 2001 he published a more detailed and complete description, in 2004 reaffirming that a new species had been discovered. In 2006, in his doctoral thesis he named this ''Gideonmantell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithopoda
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (), that started out as small, bipedal running grazers and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, dominating the North American land. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non-avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Cope a year earlier) as one of his three families of dinosaurs ( ...

Iguanodont
Iguanodontia (the iguanodonts) is a clade of herbivorous dinosaurs that lived from the Middle Jurassic to Late Cretaceous. Some members include ''Camptosaurus'', ''Dryosaurus'', ''Iguanodon'', ''Tenontosaurus'', and the hadrosaurids or "duck-billed dinosaurs". Iguanodontians were one of the first groups of dinosaurs to be found. They are among the best known of the dinosaurs, and were among the most diverse and widespread herbivorous dinosaur groups of the Cretaceous period. Classification Iguanodontia is often listed as an infraorder within a suborder Ornithopoda, though Benton (2004) lists Ornithopoda as an infraorder and does not rank Iguanodontia. Traditionally, iguanodontians were grouped into the superfamily Iguanodontoidea and family Iguanodontidae. However, phylogenetic studies show that the traditional "iguanodontids" are a paraphyletic grade leading up to the hadrosaurs (duck-billed dinosaurs). Groups like Iguanodontoidea are sometimes still used as unranked clades in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zdeněk Burian
Zdeněk Michael František Burian (11 February 1905 in Kopřivnice, Moravia, Austria-Hungary – 1 July 1981 in Prague, Czechoslovakia) was a Czech painter, book illustrator and palaeoartist whose work played a central role in the development of palaeontological reconstruction. Originally recognised only in his native Czechoslovakia, Burian's fame later spread to an international audience during a remarkable career spanning six decades (1930s to 1980s). He is regarded by many as one of the most influential palaeoartists of the modern era, and a number of subsequent artists have attempted to emulate his style. Introduction Burian was an extremely prolific artist whose works are estimated to number fifteen thousand paintings and drawings (ink pen and pencil). He illustrated many books (including natural history subjects and numerous classic novels such as ''Robinson Crusoe'', ''Tarzan of the Apes'', '' Plutonia'') and book covers, but it is within the fields of palaeontology and pal ...

Josef Augusta (paleontologist)
Josef Augusta (17 March 1903, Boskovice, Moravia – 4 February 1968, Prague) was a Czech paleontologist, geologist, and science popularizer. From 1921 to 1925 Augusta studied at the Masaryk University in Brno. Between 1933 and 1968 he held posts at the Charles University in Prague as lecturer, professor, and dean of the faculty. In addition to his scientific work (about 120 publications), Augusta wrote about twenty books popularizing his profession, mostly targeted to the youth. He is best known for his reconstructions of fossil flora and fauna, together with the painter Zdeněk Burian (1905–1981). He participated as a science adviser in the movie ''Journey to the Beginning of Time'' (1954). The dinosaur '' Burianosaurus augustai'' was named after him in 2017.

Hypsilophodon
''Hypsilophodon'' (; meaning "''Hypsilophus''-tooth") is a neornithischian dinosaur genus from the Early Cretaceous period of England. It has traditionally been considered an early member of the group Ornithopoda, but recent research has put this into question. The first remains of ''Hypsilophodon'' were found in 1849; the type species, ''Hypsilophodon foxii'', was named in 1869. Abundant fossil discoveries were made on the Isle of Wight, giving a good impression of the build of the species. It was a small, agile bipedal animal with an herbivorous or possibly omnivorous diet, measuring long and weighing . It had a pointed head equipped with a sharp beak used to bite off plant material, much like modern day parrots. Older studies have given rise to a number of misconceptions about ''Hypsilophodon'' that it was an armored, arboreal animal and that it could be found in areas outside of Wight. During the past decades, new researches have gradually shown this to be incorrect. Discov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankylopollexia
Ankylopollexia is an extinct clade of ornithischian dinosaurs that lived from the Late Jurassic to the Late Cretaceous. It is a derived clade of iguanodontian ornithopods and contains the subgroup Styracosterna. The name stems from the Greek word, “ankylos”, mistakenly taken to mean stiff, fused (in fact the adjective means bent or curved; used of fingers, it can mean hooked), and the Latin word, “pollex”, meaning thumb. Originally described in 1986 by Sereno, a most likely synapomorphic feature of a conical thumb spine defines the clade.Sereno, P.C. (1986). "Phylogeny of the bird-hipped dinosaurs (order Ornithischia)". National Geographic Research 2 (2): 234–56 First appearing around 156 million years ago, in the Jurassic, Ankylopollexia became an extremely successful and widespread clade during the Cretaceous, and were found around the world. The group died out at the end of the Maastrichtian. They grew to be quite large, comparable to some carnivorous dinosaurs and ...

Neornithischia
Neornithischia ("new ornithischians") is a clade of the dinosaur order Ornithischia. It is the sister group of the Thyreophora within the clade Genasauria. Neornithischians are united by having a thicker layer of asymmetrical enamel on the inside of their lower teeth. The teeth wore unevenly with chewing and developed sharp ridges that allowed neornithischians to break down tougher plant food than other dinosaurs. Neornithischians include a variety of basal forms historically known as "hypsilophodonts", including the Parksosauridae; in addition, there are derived forms classified in the groups Marginocephalia and Ornithopoda. The former includes clades Pachycephalosauria and Ceratopsia, while the latter typically includes ''Hypsilophodon'' and the more derived Iguanodontia. Classification Neornithischia was first named by Cooper in 1985 and defined as "all genasaurians more closely related to ''Parasaurolophus walkeri'' than to ''Ankylosaurus magniventris'' or ''Stegosaurus stenop ...

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] |
