Dsungaripterids
Dsungaripteridae is a group of pterosaurs within the suborder Pterodactyloidea. They were robust pterosaurs with good terrestrial abilities and flight honed for inland settings. Classification In 1964 Young created a family to place the recently found Chinese genus '' Dsungaripterus''. Later on, also '' Noripterus'' (then now with the name " Phobetor" which was already occupied, therefore the quotation marks) were assigned to the family. In 2003, Alexander Kellner gave the exact definition as a clade:Kellner, A.W.A., 2003. Pterosaur phylogeny and comments on the evolutionary history of the AN group. In: Buffetaut, E., Mazin, J.M. (Eds.), ''Evolution and Palaeobiology of Pterosaurs. Geological Society, London, Special Publication'' 217, 105–137. the group was composed out of the latest common ancestor of ''Dsungaripterus'', ''Noripterus'' and “Phobetor”, and all its descendants. As synapomorphies he gave the next six characteristics: a relatively small eye-socket, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noripterus
''Noripterus'' (meaning "lake wing" from Mongolian ''nuur'', "lake" and Greek ''pteron'', "wing") is a genus of dsungaripterid pterodactyloid pterosaur from Lower Cretaceous-age Lianmuqin Formation in the Junggar Basin of Xinjiang, China. It was first named by Yang Zhongjian (also known as C.C. Young in older sources) in 1973. Additional fossil remains have been recovered from Tsagaantsav Svita, Mongolia. Description The first, holotype specimen of ''Noripterus'' ( IVPP V.4062, type locality IVPP 64045) preserved the front part of the skull and lower jaws, vertebrae, and partial limbs and pelvis. ''Noripterus'' was quite similar to the contemporaneous ''Dsungaripterus'', though it was estimated to be a third shorter. It has long narrow neck vertebrae and, like ''Dsungaripterus'', a crest and no teeth in the front of the lower jaw. The teeth that are present are well-developed and spaced fairly far apart. The sharp snout is straight and not pointed upwards as with ''Dsungaripteru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dsungaripterus
''Dsungaripterus'' is a genus of dsungaripterid pterosaur with an average wingspan of . ''Dsungaripterus'' lived during the Early Cretaceous in what is now China, and its first fossil was found in the Junggar Basin. Description ''Dsungaripterus weii'' had a wing span of . Like most dsungaripteroids it had a rather robust skeleton with thick walls and stouty bodily proportions, suggesting a mostly terrestrial lifestyle. The flight style of these animals is unclear, but it was probably punctuated by abrupt landings and extensive flapping. The skull of ''Dsungaripterus'', long, bore a low bone crest that ran down from the base of the skull to halfway to the beak. ''Dsungaripteruss head and neck were together almost long. Its most notable feature are its long, narrow, upcurved jaws with a pointed tip. It had no teeth in the front part of its jaws, which were probably used to remove prey from cracks in rocks and/or the sandy, muddy inland environments it inhabited. It had knobbly ...

Lonchognathosaurus
''Lonchognathosaurus'' is a genus of dsungaripterid pterodactyloid pterosaur from the Albian-age Lower Cretaceous Lianmuqin Formation of Xinjiang, China. The genus was named in 2004 by Michael Maisch, Andreas Matzke and Sun Ge. The type species is ''Lonchognathosaurus acutirostris''. The genus name is derived from Greek , "lance", , "jaw" and , "lizard", in reference to the fact that it is a reptile with pointed jaws. The specific name means "needle snout" in Latin. ''Lonchognathosaurus'' is based on holotype SGP 2001/19, found near Urumqi in the southern Junggar Basin, the front portion of a skull and lower jaws that came from a large individual; the estimated length of the complete skull was about 400 mm (15.75 in). The point of the upper jaw, composed of the premaxilla bones, was slender and had a needle-like tip. The teeth of the upper jaw appeared far back of the tip, and were well-spaced, diminishing in size from front to back; they ended again in front of the ...

Ordosipterus
''Ordosipterus'' is a pterosaur belonging to the suborder Pterodactyloidea. Its holotype specimen was discovered in China, and dated back to the Early Cretaceous period (Aptian stage). Further analysis conclude that it was a genus of dsungaripterid pterosaur. Discovery and naming In the early 21st century, Chinese paleontologist Ji Shuan found a jaw of a pterosaur near the village of Xinzhao, which is north of Otog Qi, Inner Mongolia. The find was reported in the scientific literature in 2017.Ji SA, Lu LW, Zhang LF, Yuan CX, Jiang S, Chen XY, Hou YD, 2017, "Recent progress in the study of the Early Cretaceous dinosaur fauna from the Ordos region, Inner Mongolia". ''Geology in China'', 44 (1): 196–197 In 2020, the type and only species ''Ordosipterus planignathus'' was named and described by Ji. The generic name combines a reference to the Ordos basin with a Latinized Greek ''pteron'' (meaning "wing"). The specific name is a combination of the Latin ''planus'' (meaning "flat ...

Domeykodactylus
''Domeykodactylus'' is an extinct genus of dsungaripterid pterosaur from the Early Cretaceous (Berriasian-Albian)-age Santa Ana Formation at Quebrada de la Carreta in Antofagasta, Chile. Discovery and naming The genus was named in 2000 by David Martill, Eberhard Frey, Guillermo Chong Diaz and Charles Michael Bell. The type species is ''Domeykodactylus ceciliae''. The genus name is derived from the Cordillera Domeyko and Greek ''daktylos'', "finger" in reference to the wing finger typical of pterosaurs. The specific name honors geologist Cecilia Demargasso of the Universidad Católica del Norte, "who was so kind to us". Description ''Domeykodactylus'' is based on holotype DCGUCN 250973, found in the Sierra da Candeleros. It consists of a partial mandible; a premaxilla, present in the same rock, is referred to it as paratype. The fossil had at first been thought to belong to ''Pterodaustro''. ''Domeykodactylus'' had a crest running along the top of the premaxilla. The bon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azhdarchoidea
Azhdarchoidea (or azhdarchoids) is a group of pterosaurs within the suborder Pterodactyloidea, more specifically within the group Ornithocheiroidea. Pterosaurs belonging to this group lived throughout the Early Cretaceous, Early and Late Cretaceous periods, with one tentative member, ''Tendaguripterus'', that lived in the Late Jurassic period. The largest azhdarchoids include members of the family Azhdarchidae, examples of these are ''Quetzalcoatlus'', ''Hatzegopteryx'', and ''Arambourgiania''. The Azhdarchoidea has been recovered as either closely related to the Ctenochasmatoidea, as the sister taxon of the Pteranodontoidea within the Ornithocheiroidea, or within the Tapejaroidea, which in turn was also within the Ornithocheiroidea. Classification Azhdarchoidea was given a phylogenetic definition by David Unwin in 2003. Unwin defined the group as the most recent common ancestor of ''Quetzalcoatlus'' and ''Tapejara (pterosaur), Tapejara'', and all its descendants.Unwin, D. M., (20 ...

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'' ...

Dsungaripteroidea
Dsungaripteroidea is a group of pterosaurs within the suborder Pterodactyloidea. Evolutionary history The earliest known fossils attributed to this group are from the Kimmeridgian-age Upper Jurassic Argiles d'Octeville Formation of France, dated to around 155 million years ago, and belonging to the species ''Normannognathus wellnhoferi''.Buffetaut, E., Lepage, J.-J., and Lepage, G.
