On the phylogeny and evolutionary history of pterosaurs

Abstract Previous cladistic studies of pterosaur relationships suffer from restricted numbers of taxa and characters, incomplete data sets and absence of information on characters, tree structure and the robustness of tress. Parsimony analysis of a new character data set (60 characters, 20 terminal taxa, 97.75% complete) yielded six trees. In the strict consensus tree Preondactylus is the most basal taxon followed, stepwise, by the Dimorphodontidae and the Anurognathidae. Beyond this basal…

PRELIMINARY RESULTS OF A PHYLOGENETIC ANALYSIS OF THE PTEROSAURS FROM WESTERN LIAONING AND SURROUNDING AREAS
- Biology
- 2006
Preliminary results show that Liaoning pterosaurs belong to Anurognathidae, but the clade formed by Boreopterus and Feilongus is basal to other ornithocheirids, and three Chinese tapejarids form a monophyletic group.
Testing pterosaur ingroup relationships through broader sampling of avemetatarsalian taxa and characters and a range of phylogenetic analysis techniques
- Environmental Science, GeographyPeerJ
- 2020
This study has, for the first time, included taxa that represent the aphanosaurs, lagerpetids, silesaurids and dinosaurs, in addition to early pterosaurs, and tests the relationships between the early diverging pterosaur taxa following the addition of avemetatarsalian taxa and anatomical characters to an existing early pTerosaur dataset.

The analysis suggests that morphological evolution within anhanguerids was quite more complex than previously thought, with coloborhynchines representing the oldest recorded lineage of AnHangueridae, which achieved a worldwide distribution at least from the Aptian to the Cenomanian.

Taxonomic review of the Ornithocheirus complex (Pterosauria) from the Cretaceous of England
- BiologyZooKeys
- 2013
Investigation of the primary literature confirmed that Criorhynchus should be considered an objective junior synonym of Ornithocheirus, and a cladistic analysis demonstrates that Anhangueridae lies within a newly recognized clade, here named AnHangueria, which also includes the genera Cearadactylus, Brasileodactyls, Ludodactelus, and Camposipterus.
On wing disparity and morphological variation of the Santana Group pterosaurs

It is found that proportions of the humerus, wing metacarpal, first phalanx of the wing digit, femur and tibia are sufficient to identify partial remains of Araripe pterosaurs.

Based on several cranial features, some specimens previously referred to the genus Pteranodon are re-evaluated leading to the recognition of the following species, two of which new that are described here: PTeranodon longiceps, Geosternbergia sternbergi, Geosterbergia maiseyi sp.

Sericipterus wucaiwanensis, Angustinaripterus longicephalus, Harpactognathus gentryii represent a clade of large pterosaurs that likely lived in the terrestrial settings in which they preserved and are proposed to be widespread among the non-pterodactyloids.

The phylogenetic position of the Pterosauria within the Archosauromorpha
- Geography, Biology
- 1996
A cladistic analysis of the Archosauromorpha using characters presented by previous workers results in a single most parsimonious tree with the Pterosauria as the major sister- group of the Dinosauria, but that sister-group relationship is supported only by a suite of hindlimb characters that are correlated with bipedal digitigrade locomotion in dinosaurs.

The Cambridge Greensand pterosaur assemblage is similar to a slightly younger, but much smaller assemblages from the Lower Chalk of England and shares some elements, such as ornithocheirids, in common with many other late Early and early Late Cretaceous assemblelages.

Fossils have three major advantages: they give the only direct evidence of the order of acquisition of characters, they frequently present character combinations not found in modern forms, and they may allow the coding of characters that have been overwritten by subsequent evolution within a clade.
