The limb proportions of the extinct flying pterosaurs were clearly distinct from their living counterparts, birds and bats. Within pterosaurs, however, we show that further differences in limb proportions exist between the two main groups: the clade of short‐tailed Pterodactyloidea and the paraphyletic clades of long‐tailed rhamphorhynchoids. The hindlimb to forelimb ratios of rhamphorhynchoid pterosaurs are similar to that seen in bats, whereas those of pterodactyloids are much higher. Such a… 
Evolution of morphological disparity in pterosaurs
Comparisons of disparity based on discrete cladistic characters show that the basal paraphyletic rhamphorhynchoids (Triassic–Early Cretaceous) occupied a distinct, and relatively small, region of morphospace compared to the derived pterodactyloids (Late Jurassic–Late Cret Jurassic).

It is indicated that pterosaurs had relatively longer jaws, shorter metatarsals and shorter brachial regions compared with birds of similar size, which indicates ecological separation based on differences in size, locomotory features and feeding adaptations.
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.

Developmental data now accumulating for extant vertebrate taxa could be helpful in understanding the cellular and molecular mechanisms of body‐plan evolution in extinct vertebrates as well as extant vertebrates with unique morphology whose embryonic materials are hard to obtain.
Palaeobiology, Morphology, and Flight Characteristics of Pterodactyloid Pterosaurs
The “crocodilian-like” sequence of suture closure between the neural arches and vertebral bodies of the thoracic vertebrae is confirmed within the azhdarchoid pterosaurs, indicating that the developmental timing between the Azhdarchoidea and Ornithocheiroidea did not significantly differ.
A tiny ornithodiran archosaur from the Triassic of Madagascar and the role of miniaturization in dinosaur and pterosaur ancestry
Analysis of ancestral body size indicates that there was a pronounced miniaturization event near the common ancestor of dinosaurs and pterosaurs, and an analysis of body size evolution in dinosaurs and other archosaurs demonstrates that the earliest-diverging members of the group may have been smaller than previously thought.
The fossil record and limb disparity of enantiornithines, the dominant flying birds of the Cretaceous
Comparisons of fossil record dynamics show that enantiornithine ‘collectorship’ since the 1980s approaches an exponential distribution, indicating that an asymptote in proportion of specimens has yet to be achieved, and demonstrate that the fossil record of enantiORNithines is complete enough for the extraction of biological patterns.
The Extent of the Pterosaur Flight Membrane
It is strongly suggested that the trailing edge of the wing extended down to the lower leg or ankle in all specimens where the brachiopatagium is completely preserved, and is thus likely to have been universally present throughout the Pterosauria.
Differential Limb Scaling in the American Alligator (Alligator mississippiensis) and Its Implications for Archosaur Locomotor Evolution
The data suggest that the general forelimb proportions in relation to the hindlimb do not change significantly with increasing size in A. mississippiensis, and the negative allometry of the ulna and embryonicaly positive allometric of the third metapodials appears to be related to maintaining the functional integrity of the limbs.
Challenges and advances in the study of pterosaur flight1
In recent years, three areas of pterosaur biology have faced challenges and made advances: structure of the wing membrane, function of the pteroid, body size and mass estimates, as well as flight mechanics and aerodynamics.


Sordes pilosus and the nature of the pterosaur flight apparatus
IT is now generally accepted that pterosaurs, Mesozoic reptiles, were true fliers, but the nature of their flight apparatus is still much disputed. Evidence has been presented in favour of bird-like

It is suggested that with further analysis and data collection the relationships between flight behaviour, ecology and BI can be determined and may provide a useful tool for characterizing the ecology of fossil birds.
Bipedalism, flight, and the evolution of theropod locomotor diversity
This work addressed the hypothesis that bird hind limbs should be more disparate than those of non-avian theropods by visualizing one aspect of limb design, the proportions of the three main segments, using ternary diagrams, and shows that avian hind limb proportions are much more disparate.

The pattern of pterosaur evolution suggested by the results of this analysis is broadly similar to traditional ideas, but has greater resolution, more complexity and reveals several previously unrecognized ‘events’.

This study suggests that the most primitive taxon is the Anurognathidae, followed by Sordes and all remaining pterosaurs, and the hypothesis of rhamphorhynchoid paraphyly is confirmed, with the RhamphorHynchidae more closely related to the Pterodactyloidea than to more basal forms.

Tuning of Strouhal number for high propulsive efficiency accurately predicts how wingbeat frequency and stroke amplitude relate and scale with size and flight speed in birds
It is shown that St is a simple and accurate predictor of wingbeat frequency in birds, explaining 90% of the observed variance in a sample of 60 bird species and tuned by natural selection for high aerodynamic efficiency.
