Alioramus is another Tyrannosaur discovered in Mongolia. It is presumed now to be closely related to the slightly larger Tarbosaurus but it's unusually 'long' and 'low' skull morphology lead the original research team to conclude that this fierce predator was only a distant relative of the Tyrannosaurs living in Asia at the time. The genus name means "different branch" and the species implies that this different branch is quite distant from the rest of the family tree of Tyrannosaurs.
