Alioramus remotus Kurzanov 1976 :

In some ways, this taxon is relatively primitive, retaining a higher tooth count, lower snout, and long, more slender dentary than other tyrannosaurines. However, the ontogenetic stage of this specimen is uncertain, and these features are found in juvenile specimens of other tyrannosaurs to be lost in adulthood ( Carr 1999).In the present study Alioramus was most parsimoniously supported in a position outside the better-known and larger tyrannosaurinesl however, Currie (in press) suggests it may have shared a more recent common ancestor with Tyrannosaurus and Daspletosaurus than with Gorgosaurus and Albertosaurus .It possesses an interesting suite of primitive tyrannosaurid, derived tyrannosaurine, and autapomorphic character states (appendix 7.3). It is known only from a partial skull and associated metatarsals from the Nogon Tsav beds of the Ingeni Khoboor valley, Mongolia. The reconstruction of Kurzanov (1976) fails to correct for dorsolateral crushing of the braincase; restorations in Paul 1988 and Olshevsky 1995a correct for this and use a short rather than a pointed premaxilla.
