Qianzhousaurus is a genus of coelurosaurian theropod dinosaurs. So far only one species has been named: the type species Qianzhousaurus sinensis.[1] Nicknamed 'Pinocchio rex' for its long snout in comparison to other known tyrannosaurs, it was discovered in southern China and first published in the journal Nature Communications in May 2014.[2]

Apart from its signature snout, it also had long, narrow teeth, while T. rex had thick teeth and powerful, deep-set jaws. This suggest its feeding method and probably its life-style were quite different from Tyrannosaurus. The thinner teeth and lighter skeleton of Qianzhousaurus suggest it hunted smaller creatures, such as lizards and feathered dinosaurs.[3][4]

The bones were discovered by workmen at a construction site near the city of Ganzhou, who then took them to a local museum.[4]

The discovery of Qianzhousaurus, and Alioramus from Mongolia, shows that the long-snouted tyrannosaurids were widespread in Asia. Although we are only starting to learn about them, they were apparently one of the main groups of predatory dinosaurs in Asia.[5] Their existence was previously suspected because of various scattered fossil finds. An expert says the find "tells us pretty unequivocally that these long-snouted tyrannosaurs were a real thing. They were a different breed, living right to the end of the age of dinosaurs".[6]
