Scientists have discovered a new species of dinosaur that belonged to the same family as Tyrannosaurus rex.
The remains of the long-snouted tyrannosaur, formally named Qianzhousaurus sinensis and nicknamed Pinocchio rex, were found near the city of Ganzhou in southern China. Researchers believe the animal was a fearsome carnivore that lived more than 66 million years ago during the late Cretaceous period.
The bones were discovered on a construction site by workmen who took them to a local museum.
Experts from the Chinese Academy of Geological Sciences and the University of Edinburgh then became involved in examining the remains.
With an elongated skull and long, narrow teeth, the predator would have looked very different from a T rex, which had thick teeth and more powerful jaws.
Palaeontologists had been uncertain about the existence of long-snouted tyrannosaurs.
Previously, just two fossilised tyrannosaurs with elongated heads had been found, and since they were juveniles it was unclear whether they were from a new class of dinosaur or simply at an early growth stage.
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.
Experts at the University of Edinburgh said the new specimen was of an animal nearing adulthood. It was found largely intact and “remarkably well preserved”.
