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] |
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] |

Pachagnathus
''Pachagnathus'' ("earth jaw") is an extinct genus of non- pterodactyloid pterosaur from the late Norian–early Rhaetian-aged Quebrada del Barro Formation of Argentina. It lived in the Late Triassic period, and is one of the only known definitive Triassic pterosaurs from the southern hemisphere (along with the contemporaneous and related '' Yelaphomte''). It is also one of the few known continental Triassic pterosaurs, indicating that the absence of early pterosaurs in both the southern hemisphere and terrestrial environments is likely a sampling bias, and not a true absence. Discovery and naming The type and only known specimen of ''Pachagnathus'', PVSJ 1080, was collected during fieldwork by the Museo de Ciencias Naturales of the Universidad Nacional de San Juan from 2012 to 2014. It consists of only a broken portion of the front end of a lower jaw along its mandibular symphysis preserved in three dimensions and undistorted, including a partial tooth crown as well as several ...

Yelaphomte
''Yelaphomte'' ( Allentiac, "beast of the air") is an extinct genus of non- pterodactyloid pterosaur from the late Norian–early Rhaetian-aged Quebrada del Barro Formation of Argentina. It lived in the Late Triassic period, and is one of the only known definitive Triassic pterosaurs from the southern hemisphere (along with the contemporaneous and related ''Pachagnathus''). It was a small and crested pterosaur, although its small size may be due to immaturity. It is also one of the few known continental Triassic pterosaurs, indicating that the absence of early pterosaurs in both the southern hemisphere and terrestrial environments is likely a sampling bias, and not a true absence. Discovery and naming The type and only known specimen of ''Yelaphomte'', PVSJ 914, was collected during fieldwork by the Museo de Ciencias Naturales of the Universidad Nacional de San Juan from 2012 to 2014. It consists of only a fragment of the rostrum preserving the anterior part of both maxillae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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.

Arcticodactylus Cromptonellus
''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 ...

Carniadactylus Rosenfeldi
''Carniadactylus'' is a genus of pterosaur which existed in Europe during the Late Triassic period (late Carnian or early Norian, about 228 million years agoBarrett, P. M., Butler, R. J., Edwards, N. P., & Milner, A. R. (2008). Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref>). The genus contains a single species, ''Carniadactylus rosenfeldi''. Description ''Carniadactylus'' was similar in appearance and anatomy to its close relative ''Eudimorphodon'', though it was significantly smaller. Like ''Eudimorphodon'', it is notable for its complex multi-cusped teeth. Despite their similarities, the size difference between these two pterosaurs likely meant that they occupied different niches and relied on different food sources. This is supported by studies of their teeth. While similar in construction, the teeth of ''Carniadactylus'' show little to no wear, unlike the larger, fish-eating ''Eudimorphodon'', which may have been able to chew its food. The sma ...

Caviramidae
Caviramidae is a group of basal pterosaurs. It was erected by paleontologist Matthew G. Baron in 2020. It was defined as the least inclusive clade that includes '' Arcticodactylus cromptonellus'' and ''Caviramus schesaplanensis''. The members of Caviramidae are also considered to belong to either the family Eudimorphodontidae (''Arcticodactylus'' and ''Carniadactylus''), the family Raeticodactylidae (''Caviramus'' and ''Raeticodactylus''), or just basal eopterosaurians (''Austriadraco'' and '' Seazzadactylus''). However, Baron, the author of Caviramidae, concluded in his analyses that both Eopterosauria and Eudimorphodontidae are not monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic gro ... groups, therefore he created the family Caviramidae to contain most of the eudimorpho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
