The size and flight mechanics of giant pterosaurs have received considerable research
interest for the last century but are confused by conflicting interpretations of pterosaur …

Pterosaurs, the first true flying vertebrates, played a crucial role in Mesozoic terrestrial
ecosystems. However, our understanding of their ability to move around on the ground and …

Competing views exist on the behaviour and lifestyle of pterosaurs during the earliest
