This is the most recently discovered and unusual tyrannotyrannosaur. There is only one species, and since only an incomplete skull and skeleton is known, a skeletal restoration is not possible. One unusual point about this animal is the prominent, crinkly horn ridge on the nasals. However, such variation in horn morphology is just the kind expected between species, so this is not what makes this a seperate genus. What is really different about Alioramus is the lower jaw, which is much slimmer, straighter, longer in the dentary, and less advanced than the tyrannosaurs discussed below. The upper jaw’s large maxillary bone is also lightly built, with a larger preorbital depression. In these respects this is one of the least advanced tyrannosaurs.
Otherwise, what is known of this genus and species is typical tyrannosaur in design, and looks rather like a small Albertosau- Albertosaums rus.. The unusual nasal ridge probably supported a much more prominent and irregular nasal horn than in other tyrannosaurs, but still not as tall a one as in Ceratosaurus .
