PTEROSAUR(tair'-oh-sohr) Pterosaurs are a group of flying reptiles that, while not true dinosaurs, are said to have thrived and become extinct at the same time as the dinosaurs. The Pterosaur’s long, narrow wings are made of a thin skin membrane supported by an elongated fourth finger of each front foot. The fossil evidence suggests that these creatures were capable of active flight and also spent much time on the water. The largest, Quetzalcoatlus, has been discovered with a huge 14.4 m (48 ft) wingspread. Along with considerable evidence that such creatures lived in recent history, there are credible stories suggesting that some might still be alive today!
