Most of the known basal tyrannosauroids from Asia are relatively small fry like Dilong, Guanlong, and Xiongguanlong, with the 7.5 metre long Yutyrannus being the most famous exception. But Sinotyrannus was an even bigger beast, estimated to have achieved around 9.1 metres long and 2.8 tons, which would put it in the same size category as Albertosaurus, Daspletosaurus, and Gorgosaurus.
