Learn why the pterosaur fossils are difficult to find and why this discovery explains their evolution.
, the species found on Scotland’s Isle of Skye shows that pterosaur clades may not have been restricted to one area of the world and were more diverse than previously thought.helps to narrow down the timing of several major events in the evolution of flying reptiles," said Paul Barrett, study author and paleobiologist at the Natural History Museum,.
The new pterosaur brings scientists closer to understanding early pterosaur evolution. They now suspect that pterosaurs flew in the skies for over 25 million years. During this time, pterosaurs would have existed from the Early Jurassic to the epoch’s end. "Its appearance in the Middle Jurassic of the U.K. was a complete surprise, as most of its close relatives are from China," said Barrett.
With the fossils, researchers suspect that all pterosaur clades in the Jurassic evolved before the end of the Early Jurassic era. The winged reptiles would have lived beside avialans, modern birds’ early ancestors. Because pterosaur fossils are usually limited and incomplete, the ones found create a fragmented picture of early pterosaur evolution. The new fossil, however, while not fully complete, were of one individual. Parts of the pterosaur’s shoulders, legs, wings, and backbones were preserved in rock. Since the skeleton was encased in rock, only CT- scans could reveal parts of the ancient reptile.
