Pterosaur (Pterodactylus kochi) landing on a log,artwork. Pterosaurs,also known as pterodactyls,are an extinct group of flying reptiles that were the first vertebrates to evolve powered flight. P. kochi was a small pterosaur that lived during the Late Jurassic (155 million years ago). It had a wingspan of between 50 - 100 centimetres,a long neck and a long pointed beak containing many small teeth. In 1784,a Pterodactylus fossil unearthed by Cosimo Collini was the first pterosaur ever discovered. Fossil trackways reveal that pterosaurs were able to walk on the ground by using all four limbs | |
