Raptorex

Raptorex is a genus of tyrannosaurid dinosaur. Its fossil remains consist of a single juvenile specimen probably uncovered in Mongolia, or possibly northeastern China. The type species is R. kriegsteini, described in 2009 by Sereno and colleagues. The genus name is derived from Latin raptor, "robber", and rex, "king".

Nanotyrannus

Nanotyrannus (meaning "dwarf tyrant") is a controversial genus of tyrannosaurid dinosaur. It has long been argued that Nanotyrannus is nothing more than a juvenile of Tyrannosaurus or a similar genus.[1] The problem is that the very few skeletons found are all only fragmental.

Aublysodon

Aublysodon is a dubious genus of carnivorous dinosaurs known only from the Judith River Formation in Montana, which has been dated to the late Campanian age of the late Cretaceous period. The only currently recognized species, Aublysodon mirandus, was named by paleontologist Joseph Leidy in 1868.

Deinodon

Deinodon is a dubious tyrannosaurid dinosaur genus containing a single species, Deinodon horridus. D. horridus is known only from a set of teeth found in the Late Cretaceous Judith River Formation of Montana and named by paleontologist Joseph Leidy in 1856. 

Alioramus
