The wings of pterosaurs consisted of a narrow wing membrane or patagium primarily supported and controlled by the hyperelongate forelimb, but also attaching to the side of the body and the hindlimb. The patagium consisted of a thin sheet of extensible skin with slender structural fibers (=actinofibrils) arranged in a posterodistally radiating pattern. The function of the actinofibrils has been variously interpreted as 1) to prevent unwanted flapping of the patagium, 2) to camber the patagium… 
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.
Inferring the properties of the pterosaur wing membrane
Abstract The preservation of the wing membrane of pterosaurs is very poor and the available fossil evidence does not allow its properties to be reconstructed. In contrast, the fossil record for the
A New Model for the Evolution of the Pterosaur Wing--with a twist
The observation that many aspects of pterosaur non-wing anatomy were present in their non-volant, prolacertiform sister taxa meant that successful powered flight would have been possible only after a critical wing size had been achieved.
Three‐dimensional geometry of a pterosaur wing skeleton, and its implications for aerial and terrestrial locomotion
The joint analysis is consistent with a semi-erect quadrupedal model of terrestrial locomotion in the ornithocheirids and lends support to the idea that the pteroid – a long, slender wrist bone unique to pterosaurs that supported a membranous forewing – was directed forwards in flight, not towards the body.
Sailing the skies: the improbable aeronautical success of the pterosaurs
The forewing, supported by the unique pteroid bone, would have reduced the wings' geometric twist, and has been shown in wind tunnel tests to improve membrane stability at low angles of attack and dramatically increase the maximum lift coefficient at high angle of attack.

Wind tunnel tests on a range of possible pterosaur wing sections have substantially higher profile drag and maximum lift coefficients than those assumed before, suggesting that large pterosaurs were aerodynamically less efficient and could fly more slowly than previously estimated.
New models for the wing extension in pterosaurs
Two new models are presented here for the mechanism of the distal wing extension in pterosaurs, an extinct group of flying vertebrates, and fit with the existing fossil evidence and lay down a basis for further biomechanical and/or aerodynamical investigations.
Constraints on the wing morphology of pterosaurs

Basic mechanical and aerodynamic constraints that influenced the wing shape of pterosaurs are reviewed, and a series of theoretical modelling results are presented that show that a combination of anterior sweep and a reflexed proximal wing section provides an aerodynamically balanced and efficient theoretical pterosaur wing shape.
SEM Observation of the Wing Membrane of Beipiaopterus chenianus (Pterosauria)
Abstract The cross‐section and surface structures of wing membranes from the ctenochasmatid pterosaur Beipiaopterus chenianus were observed through a scanning electron microscope (SEM). The results


Wind tunnel modeling and biomechanical analysis of the flight dynamics of the Cretaceous pterosaur Pteranodon ingens indicates that the reptile was adequately suited to soaring and gliding flight,
A functional analysis of flying and walking in pterosaurs
An analysis of the structure and kinematics of the forelimbs and hindlimbs of pterosaurs, and functional analogy with recent and fossil vertebrates, supports a reappraisal of the locomotory abilities
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
Classical pterosaur reconstructions are variants on a ‘bat‐analogy’, whereby the wing is conceived as a simple membrane with no inherent bending strength, stretched between the arm and leg skeletons, but in recent years an alternative ‘bird‐an analogy’ has come to be generally accepted.
Terrestrial locomotion in pterosaurs
It is suggested that in pterosaurs the wing membrane was attached to the upper leg, which helped in stretching, steering and cambering.
Biomechanics of Pteranodon
The fossil evidence is re-examined to determine the structure of Pteranodon ingens, and it is suggested that extinction could have been due to climatic change, particularly an increase in the average wind speed at the end of the Cretaceous.
Exceptionally well preserved pterosaur wing membrane from the Cretaceous of Brazil
FOSSILIZED impressions of pterosaur wing membranes are known from a number of localities1,2, but true soft-tissue preservation is extremely rare3,4. We present the first description of the internal
Reinterpretation of a remarkably well preserved pterosaur soft tissue from the Early Cretaceous of Brazil
SEM analysis shows that there is no duplication of any layer and that structural fibers are absent, contrary to what would be expected in a transverse section of wing membrane, which suggests that the soft tissue is part of the integument near the shoulder girdle and thorax, and is not part of a soft tissue primarily involved in flight.
The mechanical properties of feather keratin
The possible role of the medullary foam in preventing buckling failure is still unclear; medulla removal only appears to have a minimal effect on both the stiffness and strength of whole sections of the rachis.
A Collagen and Elastic Network in the Wing of the Bat
Bundles of collagen fibrils, elastic fibres and fibroblasts are organized into a network that lies in the plane of a large portion of the bat wing and should prove a most valuable model for connective tissue studies, particularly for the study of collagen-elastin interactions.
