Abstract

In this paper, I comment on Porfiri et al. (2014), "Juvenile specimen of Megaraptor (Dinosauria, Theropoda) sheds light about tyrannosauroid radiation". Though Porfiri et al. provided numerous coelurosaurian characters on the Megaraptor specimen, their referral of the taxon to tyrannosauroidea is based on some problematic characters. Also, the specimen bears a feature which does not correspond to tyrannosauroidea. All things considered, the suggested evidences supporting the position of Megaraptora within tyrannosauroidea are weak.
