Abstract
In this paper, I comment on Larson's 2013 paper "The case for Nanotyrannus". All the osteological differences proposed by Larson (2013) seem to be due to ontogeny and individual variation. Therefore, Larson's claim that "Nanotyrannus lancensis" is not a juvenile Tyrannosaurus rex is incorrect. And based on their striking anatomical similarities, it is more parsimonious to assume that "Nanotyrannus lancensis" is the junior synonym of Tyrannosaurus rex and represents a juvenile stage of the taxon.
