Raptorex is Doomed
… or at least its reputation is. It is becoming more clear that whatever morphological distinctiveness lies at the heart of the animal we’ve come to know and love/hate as Raptorex kriegsteini (Sereno et al., 2009), its identity is going … Continue reading

The Aussie Tyrant – or Is It?
I spent some time a little bit ago rehashing an old premise of mine, that of the growing “primitive” tyrannosauroids and the grades they make. Of these, there are “true” tyrannosauroids (tyrants, roughly corresponding to Tyrannosauridae), “middle” tyrannosauroids (despots, mid-sized … Continue reading
