The new species has been named Lingwulong shenqi, meaning "amazing dragon from Lingwu."

It belonged to a subgroup of sauropods known as neosauropods which included Apatosaurus, Brachiosaurus and Diplodocus.

"We were surprised to find a close relative of Diplodocus in East Asia 174 million years ago," said study co-author Professor Paul Upchurch from University College London."It's commonly thought that sauropods did not disperse there until 200 million years ago and many of their giant descendants, reached this region much later, if at all."

The discovery suggests that our understanding of sauropod evolution is wrong.

"Our discovery of Lingwulong demonstrates that several different types of advanced sauropods must have existed at least 15 million years earlier and spread across the world while the supercontinent Pangaea was still a coherent landmass," said Upchurch.

"This forces a complete re-evaluation of the origins and evolution of these animals."
