A historic discovery in north-east China has uncovered a perfectly preserved dinosaur with wings. The 125 million-year-old creature is an imposing 2 meters (6 ft, 6in) big. It was perfectly preserved in limestone thanks to a volcanic eruption.
On the evolutionary chain, birds began to separate from dinosaurs as the Jurassic period ended about 150 million years ago. Development of two classes of species was then kicked off.
Clawed wings and teeth were sported by the Enantiorinthes, one of the new dinosaur species discovered. It was not good at flying and reached extinction 66 million years ago.
