Eudimorphodontidae
Eudimorphodontidae is an extinct family of early pterosaurs from the Late Triassic (Late Carnian to Late Rhaetian age) of Europe.Barrett, P. M., Butler, R. J., Edwards, N. P., & Milner, A. R. (2008). Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref> It was named by Peter Wellnhofer in 1978 to include ''Eudimorphodon ranzii''. Some phylogenetic analyses suggested that Eudimorphodontidae is a junior synonym of Campylognathoididae,Kellner, A. W.

Eopterosauria
Eopterosauria is a group of basal pterosaurs from the Triassic, which form their own clade. The term was first used in Andres ''et al.'' (2014) to include ''Preondactylus'', ''Austriadactylus'', ''Peteinosaurus'' and Eudimorphodontidae. Inside the group were two other new clades, Preondactylia, which included ''Preondactylus'' and ''Austriadactylus'', and Eudimorphodontoidea, to include Eudimorphodontidae and Raeticodactylidae. Eopterosauria was defined as "the least inclusive clade containing ''Preondactylus buffarinii'' and ''Eudimorphodon ranzii''". The specimen BSP 1994, previously assigned to ''Eudimorphodon'', was named the separate taxon ''Austriadraco'' in 2015, and assigned to the new family Austriadraconidae, but further classification was not described. The following phylogenetic analysis follows the topology of Andres ''et al.'' (2014). In a 2020 study of early pterosaur interrelationships carried out by Matthew G. Baron, no evidence was found to support the existen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arcticodactylus
''Arcticodactylus'' is a genus of basal pterosaur living during the Late Triassic in the area of present Greenland. Its only species was previously attributed to ''Eudimorphodon'', and its closest relatives may have been ''Eudimorphodon'' or ''Austriadraco''. History of discovery In 1989, William Amaral on the McKnight Bjerg in the east of Greenland discovered a rich fossil site. It was excavated in 1991 and 1992. Part of the material was a small skeleton of a pterosaur. In 2001, Farish Jenkins, Neil Shubin, Stephen Gatesy and Kevin Padian named and described it as a new species of ''Eudimorphodon'': ''Eudimorphodon cromptonellus''. The specific name honors Professor Alfred Walter Crompton. The suffix ''~ellus'', in Latin indicating a diminutive, alluded to the small size of the specimen. The holotype, MGUH VP 3393, was found in the Carlsberg Fjord Beds of the Ørsted Dal Member of the Fleming Fjord Formation dating from the Norian – Rhaetian. It consists of a partial skel ...

Caviramus Schesaplanensis
''Caviramus'' is a genus of caviramid pterosaur from the Late Triassic (early Rhaetian-age) lower Kössen Formation of the Northern Calcareous Alps of Switzerland. The genus was in 2006 named by Nadia Fröbisch and Jörg Fröbisch. The type species is ''Caviramus schesaplanensis''. The genus name is derived from Latin ''cavus'', "hollow" and ''ramus'', "branch". The specific name refers to Mount Schesaplana. Description The genus is based on holotype PIMUZ A/III 1225, three non-contiguous fragments of a ramus (lower jaw) of the mandible with multicuspate teeth. Two teeth are preserved, one with three cusps, and one with four; despite this difference the authors consider them as essentially isodont. The number of teeth is estimated at a minimum of twelve and a maximum of seventeen. A row of large oval foramina runs parallel to the tooth row; foramina in the form of small holes in the anterior part of the lower jaw suggest some sort of soft-tissue structure, or a keratin cove ...

Raeticodactylus Filisurensis
''Raeticodactylus'' is a genus of non-pterodactyloid pterosaur from the late Norian-early Rhaetian-age Upper Triassic lower Kössen Formation of the central Austroalpine of Grisons, Switzerland. It is known from holotype BNM 14524, a single disarticulated partial skeleton including an almost complete skull, found in August 2005. This genus was named and described in 2008 by its discoverer Rico Stecher; the type species is ''Raeticodactylus filisurensis''. The specific name refers to Filisur. Online First Description ''Raeticodactylus'' had a tall thin bony crest running along the midline of the front of the upper jaw, and a keel on the lower jaw; however, it does not seem to be closely related to ''Austriadactylus'', the only other crested Triassic pterosaur named by the time ''Raeticodactylus'' was described. The teeth at the front of the upper jaw, in the premaxillae, were fanglike, whereas the teeth in the upper cheeks (the maxillae) had three, four, or five cusps, similar t ...

Raeticodactylidae
Raeticodactylidae is a family of eudimorphodontoid eopterosaurian pterosaurs that lived in Switzerland during the Late Triassic. The family includes ''Caviramus'', and the type genus ''Raeticodactylus'', which are both known from the Kössen Formation, around 205 mya. Raeticodactylidae was first used in 2014 by Andres ''et al.'', as a group of all pterosaurs closer to ''Raeticodactylus'' than ''Eudimorphodon''. The following phylogenetic analysis follows the topology of Andres ''et al.'' (2014). In 2020 however, a study upheld by Matthew G. Baron about early pterosaur interrelationships found no evidence to support the existence of the clade Eopterosauria (the clade of which raeticodactylids might also belong to) as an early diverging clade within the Pterosauria, therefore, he sunk both ''Caviramus'' and ''Raeticodactylus'' within a clade he called Caviramidae Caviramidae is a group of basal pterosaurs. It was erected by paleontologist Matthew G. Baron in 2020. It was defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austriadactylus Cristatus
''Austriadactylus'' is a genus of "rhamphorhynchoid" pterosaur. The fossil remains were unearthed in Late Triassic (middle Norian ageBarrett, P. M., Butler, R. J., Edwards, N. P., & Milner, A. R. (2008). Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref>) rocks of Austria. The genus was named in 2002 by Fabio Marco Dalla Vecchia e.a.. The type species is ''Austriadactylus cristatus''. The genus name is derived from Latin ''Austria'' and Greek ''daktylos'', "finger", in reference to the wing finger of pterosaurs. The specific epithet means "crested" in Latin, a reference to the skull crest. The genus is based on holotype SMNS 56342, a crushed partial skeleton on a slab, found in an abandoned mine near Ankerschlag in Tyrol, in the Norian Seefelder Beds. The counterslab has been lost and with it some of the bone. The fossil consists of the skull, lower jaws, some vertebrae, parts of the limbs and pelvic girdle, and the first part of the tail.

In: Cranfield, Ingrid (ed.). ''The Illustrated Directory of Dinosaurs and Other Prehistoric Creatures''. London: Salamander Books, Ltd. Pp. 284-285. Discovery When Buffarini first discovered ''Preondactylus'', the thin slab of bituminous, dolomitic limestone containing the fossil was accidentally broken into pieces while being extracted. After reassembly the rock was cleaned with water by him and his wife and the marl and in it the bone was washed away and lost. All that was left was a negative imprint on ...

Peteinosaurus
''Peteinosaurus'' ( ; meaning "winged lizard") was a prehistoric genus of pterosaur. It lived in the late Triassic period in the late Norian age (about 221 to 210 million years ago), and at a wingspan of around , was one of the smallest and earliest pterosaurs, although other estimates suggest a wingspan of up to . Discovery Three fossils have been found near Cene, Italy. The first fossil, the holotype MCSNB 2886, is fragmentary and disarticulated. The second, the articulated paratype MCSNB 3359, lacks any diagnostic features of ''Peteinosaurus'' and thus might be a different species. This paratype has a long tail (20 cm) made more stiff by long extensions of the vertebrae; this feature is common among pterosaurs of the Triassic. The third example is MCSNB 3496, another fragmentary skeleton. All specimens are those of subadults and of none has the skull been preserved. Like most pterosaurs, ''Peteinosaurus'' had bones that were strong but very light. ''Peteinosaurus'' is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
