Synonyms

Alioramus is a genus of tyrannosaurid dinosaur. It was about 20 feet long. It lived during the Upper Cretaceous period in what is now Mongolia.

The type species, A. remotus, is known from a partial skull and three foot bones. They were got from Mongolian sediments which were deposited in a humid floodplain about 70 million years ago.[2] A second species, A. altai, known from a much more complete skeleton, was named and described in 2009.[3] Its relationships to other tyrannosaurid genera are unclear. Some evidence suggests that Alioramus is closely related to the contemporary species Tarbosaurus bataar.
