The remains of a long-snouted Tyrannosaur, nicknamed Pinocchio rex, have been discovered by workmen on a construction site near the city of Ganzhou, southern China.

The Pinocchio rex, which roamed the earth more than 66 million years ago, is believed to have been a fearsome carnivore that lived in Asia.

Researchers believe the newly-found predator's elongated skull and narrow teeth were very different from a T.rex which had thick teeth and more powerful jaws.

Experts from the Chinese Academy of Geological Sciences and the University of Edinburgh said the new specimen is of an animal nearing adulthood and was found largely intact and "remarkably well preserved".

Palaeontologists had been uncertain about the existence of long-snouted tyrannosaurs until the remains of the Pinoccio rex - whose proper name is Qianzhousaurus sinensis - were found.

It is thought that Qianzhousaurus sinensis lived alongside other tyrannosaurs but would not have been in direct competition with them, since they probably hunted different prey.

This is a different breed of tyrannosaur. It has the familiar toothy grin of T. rex, but its snout was much longer and it had a row of horns on its nose. It might have looked a little comical, but it would have been as deadly as any other tyrannosaur, and maybe even a little faster and stealthier.

Although we are only starting to learn about them, the long-snouted tyrannosaurs were apparently one of the main groups of predatory dinosaurs in Asia.

The remains have been described as a "one in a million find" and have been given to a museum in southern China.
