Targaryendraconian
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'', and ''Cimoliopterus ''Cimoliopterus'' is a genus of pterosaur that lived during the Late Cretaceous in what is now England and the United States.

Hauterivian
The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous Epoch or a stage in the Lower Cretaceous Series. It spans the time between 132.9 ± 2 Ma and 129.4 ± 1.5 Ma (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian.See Gradstein ''et al.'' (2004) for a detailed geologic timescale Stratigraphic definitions The Hauterivian was introduced in scientific literature by Swiss geologist Eugène Renevier in 1873. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel. The base of the Hauterivian is defined as the place in the stratigraphic column where the ammonite genus ''Acanthodiscus'' first appears. A reference profile for the base (a GSSP) was officially ratified by the International Union of Geological Sciences in December of 2019, and is placed in La Charce, France. The top of the Hauterivian (the base of the Barremian) is at the first appearance of ammonite species ''Spitidiscus hugii'' ...

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 ...

Iberodactylus Andreui
''Iberodactylus'' is a genus of pterodactyloid pterosaurs belonging to the clade Anhangueria, that during the Early Cretaceous lived in the area of present Spain. The type species is ''Iberodactylus andreui''. History of discovery and naming In the late 1980s, amateur paleontologist Javier Andreu discovered a pterosaur skull at the Los Quiñones site, west of Obón in Aragón. At the time it represented the most complete discovery of pterosaur fossil material in Spain apart from the remains of ''Prejanopterus''. In 2014, the find was reported in the scientific literature by José Antonio Ulloa-Rivas and identified as a member of the Ornithocheiroidea.Ulloa-Rivas, J.A. & Canudo, J.I. 2014.

Hamipterus Tianshanensis
''Hamipterus'' is an extinct genus of pteranodontoid pterosaurs from the Early Cretaceous Shengjinkou Formation of northwestern China. It is known from a single species, the type species, ''H. tianshanensis''. * Discovery and naming In 2006 from the Hami region in Xinjiang, the Shengjinkou Formation, a Konservat-Lagerstätte was reported, in this case lake sediments allowing for an exceptional preservation of fossils. The same year, Qiu Zhanxiang and Wang Banyue started official excavations. Part of the finds consisted of dense concentrations of pterosaur bones, associated with soft tissues and eggs. The site represented a nesting colony that storm floods had covered with mud. Dozens of individuals could be secured from a total that in 2014 was estimated to run into the many hundreds. In 2014, the type species ''Hamipterus tianshanensis'' was named and described by Wang Xiaolin, Alexander Kellner, Jiang Shunxing, Wang Qiang, Ma Yingxia, Yahefujiang Paidoula, Cheng Xin, Taissa Rod ...

Cimoliopterus Dunni
''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 synonym ...

Camposipterus Nasutus
''Camposipterus'' is a genus of pterodactyloid pterosaur from the Early Cretaceous of England. Fossil remains of ''Camposipterus'' dated back to the Early Cretaceous, about 112 million years ago. Discovery and naming In 1869, Harry Govier Seeley, based on a fossil found at Haslingfield, Cambridgeshire, named ''Ptenodactylus nasutus'',Seeley, H.G., 1869, ''Index to the fossil remains of Aves, Ornithosauria, and Reptilia, from the Secondary System of Strata arranged in the Woodwardian Museum of the University of Cambridge''. Deighton, Bell and Co., Cambridge, xxiii + 143 pp at the same time disclaiming the name which makes it invalid by modern standards. In 1870, Seeley had realized that the generic name ''Ptenodactylus'' had been preoccupied, so he renamed the species into '' Ornithocheirus nasutus''.Seeley, H.G., 1870, ''The Ornithosauria: an elementary study of the bones of pterodactyls, made from fossil remains found in the Cambridge Upper Greensand, and arranged in the ...

Aetodactylus Halli
''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 Cenoman ...

Targaryendraco Wiedenrothi
''Targaryendraco'' is a genus of pterodactyloid pterosaur from the Early Cretaceous period (Hauterivian stage) of Hannover, northern Germany. Fossil remains of ''Targaryendraco'' dated back about 132 million years ago. Discovery and naming In July 1984, amateur paleontologist Kurt Wiedenroth discovered a fragmentary pterosaur skeleton in the clay pit of Engelbostel at the southern edge of the city of Hanover. In 1990, Rupert Wild described the find as a new species of '' Ornithocheirus'': ''Ornithocheirus wiedenrothi''. The specific name honors Wiedenroth as discoverer. Wild considered the skeleton to lie evolutionary between ''Ornithocheirus compressirostris'' (now the holotype of ''Lonchodectes'') and ''Ornithocheirus giganteus'' (now the holotype of '' Lonchodraco''). ''O. compressirostris'' was at the time seen as the type species of '' Ornithocheirus'', but it was meanwhile shown that the correct type species is ''O. simus''. The holotype, SMNS 56628, was found in rocks o ...

Barbosania Gracilirostris
''Barbosania'' is an extinct genus of crestless targaryendraconian pterosaur from the Cretaceous Romualdo Formation of the Santana Group of northeastern Brazil, dating to the Aptian to Albian. Discovery and naming ''Barbosania'' was named and described by Ross A. Elgin and Eberhard Frey in 2011 and the type species is ''Barbosania gracilirostris''. The generic name honours Professor Miguel Barbosa of the Portuguese Museu de História Natural de Sintra in whose collection the type specimen is present. The specific epithet is derived from Latin ''rostrum'', "snout", and ''gracilis'', "slender", in reference to the slender form of the anterior skull. The holotype, MNHS/00/85, was originally acquired for Barbosa's personal collection, the basis of the new Sintra museum, from Brazilian fossil dealers. Its provenance is probably the Serra da Mãozinha (in the original article was Sierra de Maõsina, but this name is wrong), implying an Early Cretaceous late Albian age, about a ...

Aussiedraco Molnari
''Aussiedraco'' is a genus of targaryendraconian pterodactyloid pterosaur from the early Cretaceous of Australia. Description ''Aussiedraco'' is known from holotype QM F10613, a partial mandibular symphysis housed at the Queensland Museum, recovered from rocks of the Toolebuc Formation, about 70 km east of Boulia, western Queensland, dating to Albian stage. It was named by Alexander W.A. Kellner, Taissa Rodrigues and Fabiana R. Costa in 2011 and the type species is ''Aussiedraco molnari''. The generic name is derived from "Aussie", a shortened form of Australian, and "draco", from Latin meaning dragon. The specific epithet honours Ralph E. Molnar, who first described the specimen in 1980. The symphysis fragment is 88 millimetres long and very straight and narrow, with a lanceolate not-expanded tip and triangular cross-section. It lacks a keel or crest and is convex on top, with a median narrow deep groove not reaching the tip, but flat at the bottom. As far as can ...
