The osteology and functional morphology of the Late Cretaceous pterosaur Pteranodon: Part II. Size and functional morphology


The osteology and functional morphology of the Late Cretaceous pterosaur Pteranodon: Part II. Size and functional morphology



Palaeontographica, A Paläozoologie, Stratigraphie 260(1-6): 113-153



ISSN/ISBN: 0375-0442

The skeletal proportions and size distribution of the Late Cretaceous pterosaur Pteranodon are described. The functional morphology of flight is discussed and it is argued that the patagium attached to the femora which enabled the hindlimb to assist in flapping and control of the patagium. Movements of the wing provided yaw control so that the skull and cranial crest need not be interpreted as a forward rudder. Terrestrial locomotion is discussed, and it is argued that Pteranodon and other large pterodactyloids must have been bipedal. The functional morphology of the jaws and feeding are discussed, and it is argued that Pteranodon could swim and fed while swimming on the water rather than dipping food while in flight. The function of postcranial pneumaticity is also discussed.
