Pterosaurs

(wing reptiles) were close relatives of the dinosaurs and existed over the Mesozoic era, which covers the Triassic, Jurassic and Cretaceous periods, i.e. between 245 and 65 million years ago. Presumably they suffered the same fate as the dinosaurs, with the arrival of a major climatic change. The earliest discoveries of fossil remains date back to 1784 but it wasn’t until the 19th century that the reptilian nature of the creature was established. The skeletal structure showed that the 4th finger was very elongated and supported a wing, and as a result they were called Pterodactylus (wingfinger). Further study has confi rmed that they were remarkable reptiles with large brains and very effective lungs and circulatory systems, making them highly specialised flying creatures. They were able to flap and soar in the turbulent skies of ancient times and would have been quite a terrifying sight. Many varieties have been found, with sizes ranging from the wingspan of a sparrow to Quetzalcoatlus at 50’ (15.2m). Their skulls and teeth evolved to specialise on the type of food that was available, ranging from fi sh to carrion. Many of them had projections from the skull that may have functioned as an aerodynamic balance for the head, or for steering, or possibly making noise.

Apparently winged reptiles were very efficient flyers, a characteristic that seems to have been transferred to the model.
