Pterosaurs (Nemicolopterus crypticus) perched on tree branches, artwork. Pterosaurs, also known as pterodactyls, are an extinct group of flying reptiles that were the first vertebrates to evolve powered flight. N. crypticus lived during the Early Cretaceous, 120 million years ago. It had a wingspan of 25 centimetres, making it one of the smallest pterosaur species discovered. It had curved foot bones possibly adapted for perching and climbing amongst trees. N. crypticus was discovered in Liaoning province, China. It is thought to have fed on a diet of small insects.
