West Liaoning Found to be an Origin Area of Cretaceous Pterosaurs

摘要

The fresh discoveries on pterosaurs by CAS researchers from the Jehol Fauna in the northeast China's Liaoning Province might shed new light on the studies of the extinct flying reptile that once ruled the skies for 160 million years in the Jurassic and Cretaceous periods. They make scientists to speculate that the western backwater of Liaoning could be one of the origin centers, from which the diverse populations of pterosaurs first made debut hundreds of thousand years ago.
