Icarosaurus Copy
''Icarosaurus'' (meaning "Icarus lizard") is an extinct genus of kuehneosaurid reptile from the Late Triassic (Norian age) Lower Lockatong Formation of New Jersey.Berg, T.M., ''et al''. (1983). Stratigraphic Correlation Chart of Pennsylvania: G75, Pennsylvania Geologic Survey, Harrisburg, Pennsylvania. It is closely related to lizards and the tuatara. Based on a partial skeleton missing part of the tail, some ribs, a hand, and parts of the legs, it was a small animal, about 10 centimeters (4 in) long from the skull to the hips. Like its relative ''Kuehneosaurus'', it was able to glide short distances using 'wings' consisting of highly elongated ribs covered with skin. These gliding membranes would have had a convex upper surface and a concave lower surface, thus creating a simple airfoil structure well-suited to gliding. This method of gliding is also seen in ''Coelurosauravus'' and the modern ''Draco'', neither of which are closely related to ''Icarosaurus''. Discovery ...

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 ...

Kuehneosaurus
''Kuehneosaurus'' is an extinct genus of Late Triassic kuehneosaurid reptile known from the Late Triassic ( Norian stage) of the Penarth Group of southwest England and the Steinmergel Group of Luxembourg. Temperature at this stage and region would have ranged from 28 to 35 °C. It was named by P. L. Robinson in 1962 in honour of paleontologist Walther Kühn, and the type and only species is ''Kuehneosaurus latus''. Measuring 72 centimetres long (2.3 feet), it had "wings" formed from ribs which jutted out from its body by as much as 14.3 cm, connected by a membrane which allowed it to slow its descent when jumping from trees. It is a member of a family of extinct gliding reptiles, the Kuehneosauridae, within a larger living group the Lepidosauromorpha, which contain modern lizards and tuatara.Evans, S.C. (2003). "At the feet of the dinosaurs: the early history and radiation of lizards." ''Biological Reviews'', 78: 513–551. Unlike its longer "winged" relative '' Kuehneos ...

Triassic Lepidosauromorphs
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archosaurs ...

North Bergen
North Bergen is a township in the northern part of Hudson County, New Jersey, United States. As of the 2020 U.S. census, the township had a total population of 63,361. The township was founded in 1843. It was much diminished in territory by a series of secessions. Situated on the Hudson Palisades, it is one of the hilliest municipalities in the United States. Like neighboring North Hudson communities, North Bergen is among those places in the nation with the highest population density and a majority Hispanic population. History Colonial era At the time of European colonization the area was the territory of Hackensack tribe of the Lenape Native Americans, who maintained a settlement, Espatingh, on the west side of the hills and where a Dutch trading post was established after the Peach Tree War. In 1658, Peter Stuyvesant, then Director-General of New Netherland, repurchased from them the area now encompassed by the municipalities of Hudson County east of the Hackensack Rive ...

Draco (genus)
''Draco'' is a genus of agamid lizards that are also known as flying lizards, flying dragons or gliding lizards. These lizards are capable of gliding flight via membranes that may be extended to create wings (patagia), formed by an enlarged set of ribs. They are arboreal insectivores. While not capable of powered flight they often obtain lift in the course of their gliding flights. Glides as long as have been recorded, over which the animal loses only in height, which is quite some distance, considering that one lizard is only around in total length, tail included. Piper, Ross (2007). 'Extraordinary Animals: An Encyclopedia of Curious and Unusual Animals'. Santa Barbara, California: Greenwood Press. They are found across Southeast Asia and southern India. and are fairly common in forests, areca gardens, teak plantations and shrub jungle. History of discovery Carl Linnaeus described the genus in 1758, with the type species being ''Draco volans.'' The name of the genus is fr ...

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] |
Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...

Skin
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other cuticle, animal coverings, such as the arthropod exoskeleton, have different cellular differentiation, developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ (anatomy), organ of the integumentary system made up of multiple layers of ectodermal tissue (biology), tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/os clitoris.
