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. 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".
