Peteinosaurus Zambellii
''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] |
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.

Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref> that inhabited what is now Italy. It contains a single known species, ''Preondactylus buffarinii'', which was discovered by Nando Buffarini in 1982 at the Forni Dolostone near Udine in the Preone valley of the Italian Alps."Preondactylus." 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 ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Macronychoptera
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectivo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudimorphodontoidea
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 existenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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 ...

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 groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...
