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
TLDR
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

TLDR
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 Earliest Pterodactyloid and the Origin of the Group
A taxonomic and phylogenetic review of the anhanguerid pterosaur group Coloborhynchinae and the new clade Tropeognathinae
TLDR
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.

TLDR
Phylogenetic analysis of all Texas pterosaurs that can be coded for more than one character confirms that these species are distinct from others and occupy phylogenetic positions close to their original classifications.
Taxonomic review of the Ornithocheirus complex (Pterosauria) from the Cretaceous of England
TLDR
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
TLDR
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.
Comments on the Pteranodontidae (Pterosauria, Pterodactyloidea) with the description of two new species.
TLDR
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.
A New Rhamphorhynchid Pterosaur from the Upper Jurassic of Xinjiang, China, and the Phylogenetic Relationships of Basal Pterosaurs
TLDR
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.
A new azhdarchoid pterosaur from the Lower Cretaceous of China and its implications for pterosaur phylogeny and evolution
TLDR
A complete, articulated skeleton of a 1.4-m-wingspan pterosaur from the Lower Cretaceous Jiufotang Formation of Liaoning Province, China is reported and it is identified as a new genus and species, Shenzhoupterus chaoyangensis gen. nov.

The phylogenetic position of the Pterosauria within the Archosauromorpha
TLDR
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.
Classification and phylogeny of the diapsid reptiles

TLDR
A cladistic analysis of skull and skeletal characters of all described Permo-Triassic diapsid reptiles suggests some significant rearrangements to commonly held views of the Diapsida.
An overview of the pterosaur assemblage from the Cambridge Greensand (Cretaceous) of Eastern England
TLDR
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.
Scleromochlus taylori and the origin of dinosaurs and pterosaurs
TLDR
A reanalysis of crown–group archosaur relationships confirms the split into Crurotarsi (crocodile relatives) and Ornithodira (bird relatives), as well as the clear division of Ornithadira into Pterosauria and Dinosauromorpha.
Osteology and Phylogenetic Relationships of Fossil and Recent Paddlefishes (Polyodontidae) with Comments on the Interrelationships of Acipenseriformes
ABSTRACT The comparative osteology and phylogenetic relationships of fossil and living paddlefishes (Polyodontidae) are investigated in detail for the first time. This peculiar, poorly known group is…
First record ofColoborhynchus (Pterosauria) from the Santana Formation (Lower Cretaceous) of the Chapada do Araripe, Brazil
The anterior tips of associated upper and lower jaws of a pterosaur from the Lower Cretaceous of Brazil are described and assigned to the taxonColoborhynchus in the family Ornithocheiridae. It is…
A STATISTICAL STUDY OF RHAMPHORHYNCHUS FROM THE SOLNHOFEN LIMESTONE OF GERMANY: YEAR-CLASSES OF A SINGLE LARGE SPECIES
TLDR
It is shown that the five nominal species of Rhamphorhynchus were based on characters related to size and ontogeny, and represent juveniles, subadults, and adults of a single large species.
On the systematic and stratigraphic significance of pterosaurs from the Lower Cretaceous Yixian Formation (Jehol Group) of Liaoning, China
Abstract. A reassessment of the systematic relationships of pterosaurs from the Lower Cretaceous Yixian Formation of Liaoning Province, China, shows that Dendrorhynchoides should be reassigned to the…
Missing data and rhynchosaur phylogeny
TLDR
The use of disqualifiers faithful trees are investigated as a framework for representing consensus relationships and a method of determining the possible positions of taxa that are excluded from a disqualifier faithful tree is described.
Testing the time axis of phylogenies
TLDR
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.
