List Of Pterosaurs
This list of pterosaurs is a comprehensive listing of all genera that have ever been included in the order Pterosauria, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomen dubium''), or were not formally published ('' nomen nudum''), as well as junior synonyms of more established names, and genera that are no longer considered pterosaurian. The list currently includes 263 genera. Scope and terminology There is no official, canonical list of pterosaur genera, but the most thorough attempts can be found at the Pterosauria section of Mikko Haaramo's ''Phylogeny Archive'', the Genus Index at Mike Hanson's ''The Pterosauria'', supplemented by the Pterosaur Species List, and in the fourth supplement of Donald F. Glut's ''Dinosaurs: The Encyclopedia'' series. Authors and year The authors column lists the authors of the formal description responsible for the erection of the genus listed ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Aidachar
''Aidachar'' (named for Aydahar, a mythical Kazakh dragon) is an extinct genus of ichthyodectiform teleost ray-finned fish from the Late Cretaceous of Kyzyl Kum, central Asia. It was named by Lev Nesov in 1981. At first, he tentatively described the fossil material as the jaw fragments of a ctenochasmatid pterosaur (a flying reptile), but reinterpreted ''Aidachar'' as a fish in 1986. The type species is ''A. paludalis''. Second species, ''A. pankowskii'', is described from Kem Kem Group and reclassified from genus ''Cladocyclus ''Cladocyclus'' (derived from the Greek κλάδος/kládos ("branch") and κύκλος/kýklos ("circle")) is an extinct genus of Ichthyodectidae.

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrotapejara
''Afrotapejara'' (meaning "African old being") is an extinct genus of tapejarid pterosaur discovered in Morocco. The type species, ''Afrotapejara zouhri'', was named and described in 2020. It was the first tapejarid discovered in Africa and the fourth pterosaur discovered in the Kem Kem Beds. Discovery British paleontologist David Michael Martill acquired a pterosaur jaw from a fossil trader at Erfoud. It would have been excavated at the plateau of Ikhf N’ Taqmout, in Tafilalt. In 2020, the type species ''Afrotapejara zouhri'' was named and described by David Martill, Roy Smith, David M. Unwin, Alexander Kao, James McPhee and Nizar Ibrahim. The generic name combines references to Africa and the related genus '' Tapejara''. The specific name honours the Moroccan paleontologist Samir Zouhri. The holotype, FSAC-KK 5004, had been found in the Kem-Kem Beds, dating from the Albian - early Cenomanian. It consists of a snout lacking the front tip and extending to behind to a posit ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Aetodactylus
''Aetodactylus'' (meaning "eagle finger") is a genus of targaryendraconian pterosaur. It is known from a lower jaw discovered in Upper Cretaceous rocks of northeastern Texas, United States. Description ''Aetodactylus'' is based on SMU 76383 (Shuler Museum of Paleontology, Southern Methodist University), a nearly complete lower jaw lacking the right retroarticular process (the bony prong posterior to the jaw joint), part of the posterior end of the mandibular symphysis (where the two halves of the lower jaw meet), and all but two teeth. This specimen was found in 2006 by Lance Hall near a construction site in Mansfield, near Joe Pool Lake (recorded as SMU Loc. 424). The rock it was found in is a calcareous marine sandstone rich in mud–sized particles, from the middle Cenomanian-age (approximately 97 million years old) Tarrant Formation. Also found were fish teeth and vertebrae, and indeterminate bones. The Tarrant Formation is the lowest rock unit of the Cenom ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

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] |
