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 ...

Cimoliopterus
''Cimoliopterus'' is a genus of pterosaur that lived during the Late Cretaceous in what is now England and the United States. The first known specimen, consisting of the front part of a snout including part of a crest, was discovered in the Grey Chalk Subgroup of Kent, England, and described as the new species ''Pterodactylus cuvieri'' in 1851. The specific name ''cuvieri'' honours the palaeontologist George Cuvier, whereas the genus ''Pterodactylus'' was then used for many pterosaur species that are not thought to be closely related today. It was one of the first pterosaurs to be depicted as models in Crystal Palace Park in the 1850s. The species was subsequently assigned to various other genera, including ''Ornithocheirus'' and ''Anhanguera''. In 2013, the species was moved to a new genus, as ''Cimoliopterus cuvieri''; the generic name ''Cimoliopterus'' is derived from the Greek words for "chalk" and "wing". Other specimens and species have also been assigned to or synonymi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Targaryendraconia
Targaryendraconia is an extinct clade of lanceodontian pterosaurs that lived from the Early to Late Cretaceous period in Europe, North America, South America, and Australia. Classification Below is a cladogram following a topology by Pêgas and colleagues in 2019. In their analysis, they recovered Targaryendraconia as the sister taxon of the clade Anhangueria, both of which are within the more inclusive group Ornithocheirae. Targaryendraconia is split into two families: the Targaryendraconidae, which contains ''Aussiedraco'', '' Barbosania'', and ''Targaryendraco'', and the Cimoliopteridae, which contains ''Aetodactylus'', ''Camposipterus ''Camposipterus'' is a genus of pterodactyloid pterosaur from the Early Cretaceous of England.

2010 In Archosaur Paleontology
The year 2010 in Archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is the scientific study of those animals, especially as they existed before the Holocene Epoch began about 11,700 years ago. The year 2010 in paleontology included various significant developments regarding archosaurs. This article records new taxa of fossil archosaurs of every kind that have been described during the year 2010, as well as other significant discoveries and events related to paleontology of archosaurs that occurred in the year 2010.

Boreopterus
''Boreopterus'' is a genus of boreopterid pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Yixian Formation of Dalian, Liaoning, China. Etymology ''Boreopterus'' was named in 2005 by Lü Junchang and Ji Qiang. The type species is ''Boreopterus cuiae''. The genus name is derived from Greek ''boreios'', "northern" and ''pteron'', "wing". The specific epithet honors Cui Xu. Description ''Boreopterus'' is based on holotype JZMP-04-07-3, a nearly complete but crushed skeleton and skull. The skull is 235 millimeters long (9.25 inches), low and elongated with a rounded tip. Its wingspan is estimated to have been around 1.45 meters (4.76 feet). Its teeth, especially the anterior nine pairs, are quite large, forming a mesh of sharp teeth at the front of the mouth; the third and fourth teeth from the front are the largest. There are at least 27 teeth in each side of both the upper and lower jaws, which is a large amount. Classification Lü and Ji ...

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] |
Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...

Ornithocheirus
''Ornithocheirus'' (from Ancient Greek "ὄρνις", meaning ''bird'', and "χεῖρ", meaning ''hand'') is a pterosaur genus known from fragmentary fossil remains uncovered from sediments in the UK and possibly Morocco. Several species have been referred to the genus, most of which are now considered as dubious species, or members of different genera, and the genus is now often considered to include only the type species, ''Ornithocheirus simus''. Species have been referred to ''Ornithocheirus'' from the mid-Cretaceous period of both Europe and South America, but ''O. simus'' is known only from the UK, though a specimen referred to ''O.'' cf. ''simus'' is also known from Morocco. Because ''O. simus'' was originally named based on poorly preserved fossil material, the genus ''Ornithocheirus'' has suffered enduring problems of zoological nomenclature. Fossil remains of ''Ornithocheirus'' have been recovered mainly from the Cambridge Greensand of England, dating to the beginni ...

Coloborhynchus
''Coloborhynchus'' is a genus of pterodactyloid pterosaur belonging to the family Anhangueridae, though it has also been recovered as a member of the Ornithocheiridae in some studies. ''Coloborhynchus'' is known from the Lower Cretaceous of England (Valanginian age, 140 to 136 million years ago), and depending on which species are included, possibly the Albian and Cenomanian ages (113 to 93.9 million years ago) as well. ''Coloborhynchus'' was once thought to be the largest known toothed pterosaur, however, a specimen of the closely related ''Tropeognathus'' is now thought to have had a larger wingspan. History and classification Like many ornithocheiroid pterosaurs named during the 19th century, ''Coloborhynchus'' has a highly convoluted history of classification. Over the years numerous species have been assigned to it, and often, species have been shuffled between ''Coloborhynchus'' and related genera by various researchers. In 1874 Richard Owen, rejecting the creation by H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anhanguera (pterosaur)
''Anhanguera'' () is a genus of pterodactyloid pterosaur known from the Early Cretaceous (Albian age, 125 to 112 million years ago) Romualdo Formation of Brazil and the Late Cretaceous ( Cenomanian age, 98 to 92.5 million years ago) Kem Kem Group of Morocco. This pterosaur is closely related to ''Ornithocheirus'', but belongs in the family Anhangueridae.Campos, D. de A., and Kellner, A. W. (1985). "Um novo exemplar de ''Anhanguera blittersdorffi'' (Reptilia, Pterosauria) da formação Santana, Cretaceo Inferior do Nordeste do Brasil." In Congresso Brasileiro de Paleontologia, Rio de Janeiro, Resumos, p. 13. The generic name comes from the Tupi words ''añanga'', meaning "spirit protector of the animals" + ''wera'' "bygone".

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
