Argiles D'Octeville
The Argiles d'Octeville (meaning Octeville-sur-Mer, Octeville Clay) is a geological Formation (geology), formation in Normandy, France. It dates back to the Kimmeridgian stage of the Late Jurassic.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Jurassic, Europe)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 545–549. .

Paleogeography And Paleoclimate Of The Late Jurassic - 150 Ma With Dinosaur Fossil Localities
Palaeogeography (or paleogeography) is the study of historical geography, generally physical landscapes. Palaeogeography can also include the study of human or cultural environments. When the focus is specifically on landforms, the term paleogeomorphology is sometimes used instead. Paleomagnetism, paleobiogeography, and tectonic history are among its main tools. Palaeogeography yields information that is crucial to scientific understanding in a variety of contexts. For example, palaeogeographical analysis of sedimentary basins plays a key role in the field of petroleum geology, because ancient geomorphological environments of the Earth's surface are preserved in the stratigraphic record. Palaeogeographers also study the sedimentary environment associated with fossils for clues to the evolutionary development of extinct species. Palaeogeography is furthermore crucial to the understanding of palaeoclimatology, due to the impact of the positions of continents and oceans on influe ...

Jurassic System Of Europe
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassic, t ...

Pelorosaurus
''Pelorosaurus'' ( ; meaning "monstrous lizard") is a genus of titanosauriform sauropod dinosaur. Remains referred to ''Pelorosaurus'' date from the Early Cretaceous period, about 140-125 million years ago, and have been found in England and Portugal. Thomas Holtz estimated its length at 24 meters (79 feet). The name ''Pelorosaurus'' was one of the first to be given to any sauropod. Many species have been assigned to the genus historically, but most are currently considered to belong to other genera. Problematically, the first named species of ''Pelorosaurus'', ''P.conybeari'', is a junior synonym of ''Cetiosaurus brevis''. History ''Pelorosaurus'' was the first sauropod to be identified as a dinosaur, although it was not the first to be discovered. Richard Owen had discovered ''Cetiosaurus'' in 1841 but had incorrectly identified it as a gigantic sea-going crocodile-like reptile. Mantell identified ''Pelorosaurus'' as a dinosaur, living on land. The taxonomic history of ''Pelo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauropoda
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Monofenestrata
Monofenestrata is an unranked group of pterosaurs that includes the family Wukongopteridae and the suborder Pterodactyloidea. The clade Monofenestrata was in 2009/2010 defined as the group consisting of ''Pterodactylus'' and all species sharing with ''Pterodactylus'' the synapomorphy of an external nostril confluent with the antorbital fenestra, the major skull opening on the side of the snout. The name is derived from Greek ''monos'', "single", and Latin ''fenestra'', "window". The concept was inspired by the discovery of ''Darwinopterus'', a species combining a pterodactyloid-type skull with a more basal build of the remainder of the body. The Darwinoptera, a primitive subgroup of monofenestratans showing this transitional anatomy, was also named for ''Darwinopterus'' and defined as all descendants of its common ancestor with '' Pterorhynchus''. The earliest known monofenestratan fossils have been found in the Stonesfield Slate formation of the United Kingdom, which dates to t ...

Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normannognathus
''Normannognathus'' is a genus of pterosaur from the Kimmeridgian-age Upper Jurassic Argiles d'Octeville Formation of France. Initially, ''Normannognathus'' was classified to the family Germanodactylidae, sister taxon to ''Germanodactylus'', however, many recent analysis have recovered ''Normannognathus'' in different phylogenetic positions, and depending on different authors, ''Normannognathus'' is either found as a basal member of the Dsungaripteroidea, as an indeterminate monofenestratan, or as the sister taxon of '' Cycnorhamphus'' within the family Gallodactylidae. Discovery and naming In 1993, Jean-Jacques Lepage on the Normandy coast at the Cap de la Hève, near Ecqueville, Octeville-sur-Mer, Seine-Maritime, Normandy, found a ten centimetres long fossil of a pterosaur in a marine claystone layer. In 1998, Eric Buffetaut ''et al.'' named a separate genus for it. The type species is ''Normannognathus wellnhoferi''. The genus name is derived from ''Normannia'', the Med ...

Dacentrurus Drawing
''Dacentrurus'' (meaning "tail full of points"), originally known as ''Omosaurus'', is a genus of stegosaurian dinosaur from the Late Jurassic to Early Cretaceous (154 - 140 mya) of Europe. Its type species, ''Omosaurus armatus'', was named in 1875, based on a skeleton found in a clay pit in the Kimmeridge Clay in Swindon, England. In 1902 the genus was renamed ''Dacentrurus'' because the name ''Omosaurus'' had already been used for a crocodylian. After 1875, half a dozen other species would be named but perhaps only ''Dacentrurus armatus'' is valid. Finds of this animal have been limited and much of its appearance is uncertain. It was a heavily built quadrupedal herbivore, adorned with plates and spikes, reaching in length and in body mass. Discovery and species On 23 May 1874, James Shopland of the Swindon Brick and Tyle Company reported to Professor Richard Owen that their clay pit, the Swindon Great Quarry below Old Swindon Hill at Swindon in Wiltshire, had again p ...

Franz Nopcsa Von Felső-Szilvás
Baron Franz Nopcsa von Felső-Szilvás (also Baron Nopcsa von Felső-Szilvás, Baron Nopcsa, Ferenc Nopcsa, báró felsőszilvási Nopcsa Ferenc, Baron Franz Nopcsa, and Franz Baron Nopcsa; May 3, 1877 – April 25, 1933) was a Hungarian Aristocracy (class), aristocrat, adventurer, scholar, geologist, Paleontology, paleontologist and albanologist. He is widely regarded as one of the founders of paleobiology, and first described the theory of insular dwarfism. He was also a specialist on Albanology, Albanian studies and completed the first geological map of northern Albania. The essay, first published on Elsie's website, is the basis for the "Introduction" to Nopcsa's memoirs titled ''Traveler, Scholar, Political Adventurer'' (2014) edited by Robert Elsie. Life Nopcsa was born in 1877 in Déva, Transylvania, Kingdom of Hungary (today Deva, Romania), to the Hungarian nobility, Hungarian Nopcsa Aristocracy (class), aristocratic family of Romanians in Hungary, Romanian origin.

Stegosauria
Stegosauria is a group of herbivorous ornithischian dinosaurs that lived during the Jurassic and early Cretaceous periods. Stegosaurian fossils have been found mostly in the Northern Hemisphere, predominantly in what is now North America, Europe, Africa, South America and Asia. Their geographical origins are unclear; the earliest unequivocal stegosaurian, ''Huayangosaurus taibaii'', lived in China. Stegosaurians were armored dinosaurs (thyreophorans). Originally, they did not differ much from more primitive members of that group, being small, low-slung, running animals protected by armored scutes. An early evolutionary innovation was the development of spikes as defensive weapons. Later species, belonging to a subgroup called the Stegosauridae, became larger, and developed long hindlimbs that no longer allowed them to run. This increased the importance of active defence by the thagomizer, which could ward off even large predators because the tail was in a higher position, pointing ...
