Sharovipteryx
''Sharovipteryx'' ("Sharov's wing", known until 1981 as ''Podopteryx'', "foot wing"), is a genus of early gliding reptiles containing the single species ''Sharovipteryx mirabilis''. It is known from a single fossil and is the only glider with a membrane surrounding the pelvis instead of the pectoral girdle. This lizard-like reptile was found in 1965 in the Madygen Formation, Dzailauchou, on the southwest edge of the Fergana Valley in Kyrgyzstan, in what was then the Asian part of the U.S.S.R. dating to the middle-late Triassic period (about 225 million years ago). The Madygen horizon displays flora that put it in the Upper Triassic. An unusual reptile, ''Longisquama,'' was also found there. ''S. mirabilis'' is known from a unique holotype specimen, which was first described by Aleksandr Grigorevich Sharov in 1971.Sharov, A. G. 1971.

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Carnian Genera
The Carnian (less commonly, Karnian) is the lowermost stage of the Upper Triassic Series (or earliest age of the Late Triassic Epoch). It lasted from 237 to 227 million years ago (Ma). The Carnian is preceded by the Ladinian and is followed by the Norian. Its boundaries are not characterized by major extinctions or biotic turnovers, but a climatic event (known as the Carnian pluvial episode characterized by substantial rainfall) occurred during the Carnian and seems to be associated with important extinctions or biotic radiations. Stratigraphic definitions The Carnian was named in 1869 by Mojsisovics. It is unclear if it was named after the Carnic Alps or after the Austrian region of Carinthia (''Kärnten'' in German) or after the Carnia historical region in northwestern Italy. The name, however, was first used referring to a part of the Hallstatt Limestone cropping out in Austria. The base of the Carnian Stage is defined as the place in the stratigraphic record where the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Reptile Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Draco Volans
''Draco volans'', also commonly known as the common flying dragon, is a species of lizard in the family Agamidae. The species is endemic to Southeast Asia. www.reptile-database.org. Like other members of genus ''Draco'', this species has the ability to glide using winglike lateral extensions of skin called patagia.Crew, Bec (2014"Flying dragon lizard a true gliding reptile".''Australian Geographic''. 29 May 2014. Description ''Draco volans'' grows to a length of up to , including the tail. The body is tan in color with dark flecks. The patagium of the male is tan to bright orange with dark banding. The female's patagium has irregular markings rather than banding. EcologyAsia. Courtship The coloration of the patagia and the |
Coelurosauravus
''Coelurosauravus'' (meaning "hollow lizard grandfather") is a genus of basal diapsid reptiles, known from the Late Permian of Madagascar. Like other members of the family Weigeltisauridae, members of this genus possessed long, rod-like ossifications projecting outwards from the body. These bony rods were not extensions of the ribs but were instead newly developed bones derived from the skin of the animal, a feature unique to weigeltisaurids. It is believed that during life, these structures formed folding wings used for gliding flight, similar to living gliding ''Draco'' lizards. ''Coelurosauravus'' is solely known from the type species, ''C. elivensis'', which was named by Jean Piveteau in 1926 based on fossils from the Lower Sakamena Formation of Madagascar. The species ''Weigeltisaurus jaekeli'' from Europe was formerly considered a species of ''Coelurosauravus'', but is now considered distinct. History of discovery The only known specimens of ''Coelurosauravus'' were coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tanystropheidae
Tanystropheidae is an extinct family of mostly marine archosauromorph reptiles that lived throughout the Triassic Period. They are characterized by their long, stiff necks formed from elongated cervical vertebrae with very long cervical ribs. Some tanystropheids such as ''Tanystropheus'' had necks that were several meters long, longer than the rest of their bodies. Tanystropheids are known from Europe, Asia (Russia, China, and Saudi Arabia), North America and probably South America (Brazil). The presence of tanystropheids in Europe and China indicate that they lived along much of the coastline of the Tethys Ocean. However, species in western North America are found in terrestrial deposits, suggesting that as a group, tanystropheids were ecologically diverse. Relationships among tanystropheid species have been difficult to resolve because most specimens were flattened during fossilization and are preserved two-dimensionally. Three-dimensional fossils are known from Europe and N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozimek Volans
''Ozimek'' (named after the Ozimek, town of the same name) is a genus of sharovipterygidae, sharovipterygid archosauromorpha, archosauromorph reptile, known from Late Triassic deposits in Poland and closely related to the Kyrgyzstani ''Sharovipteryx''. It contains one species, ''O. volans'', named in 2016 by Jerzy Dzik and Tomasz Sulej. Like ''Sharovipteryx'', ''Ozimek'' had long, slender limbs with the hindlimbs longer than the forelimbs; the hindlimbs likely supported gliding membranes as fossilized in ''Sharovipteryx''. Another unusual characteristic was the shoulder girdle, where the massive coracoids formed a shield-like structure covering the bottom of the shoulder region that would have limited mobility. In other respects, such as its long neck, it was a typical member of the non-natural grouping Protorosauria. Phylogenetic analysis has indicated that it, possibly along with ''Sharovipteryx'', may have been an unusual member of the protorosaur group Tanystropheidae, althoug ...

Prolacertiformes
Protorosauria is an extinct polyphyletic group of archosauromorph reptiles from the latest Middle Permian (Capitanian stage) to the end of the Late Triassic (Rhaetian stage) of Asia, Europe and North America. It was named by the English anatomist and paleontologist Thomas Henry Huxley in 1871 as an order, originally to solely contain ''Protorosaurus''. Other names which were once considered equivalent to Protorosauria include Prolacertiformes and Prolacertilia. Protorosaurs are distinguished by their long necks formed by elongated cervical vertebrae, which have ribs that extend backward to the vertebrae behind them. Protorosaurs also have a gap between the quadrate bones and the jugal bones in the back of the skull near the jaw joint, making their skulls resemble those of lizards. While previously thought to be monophyletic, the group is now though to consist of various groups of basal archosauromorph reptiles that lie outside Crocopoda. Classification Protorosauria was consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
