 Of the two subfamilies , tyrannosaurines appear to have been more widespread . Albertosaurines are unknown in Asia , which was home to the tyrannosaurines such as Tarbosaurus and Zhuchengtyrannus , and Qianzhousaurus and Alioramus of the Alioramini . Both subfamilies of Tyrannosaurinae and Albertosaurinae were present in the Campanian and early Maastrichtian stages of North America , with tyrannosaurines like Daspletosaurus ranging throughout the Western Interior , while the albertosaurines Albertosaurus and Gorgosaurus are currently known only from the northwestern part of the continent .
