… 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
Nanotyrannus is everyone’s favorite tyrannosaur, as long as it’s right behind the big guy, Tyrannosaurus, itself. It’s been lovingly depicted and aggressively championed by such notable figures as Robert Bakker, and supported less enthusiastically but no less masterfully by Philip … Continue reading

One of the things that I’ve been itching to do is generate a database of variation in dental series across a variety of taxa, virtually most if not all variations of archosaurs and beyond. This is to assess the quality … Continue reading

Of these, there are “true” tyrannosauroids (tyrants, roughly corresponding to Tyrannosauridae), “middle” tyrannosauroids (despots, mid-sized … Continue reading
The origin and evolution of Tyrannosauroidea  is one of the interesting puzzles in theropod phylogeny (the only one more fascination (with all due apologies to Tom Holtz) . Inclusion of tyrannosaurids is a no-brainer, but the origin of tyrannosaurs … Continue reading
Paul Sereno, world famous for his far-flung and well-publicized discoveries and descriptions, will be adding a new taxon name to his roster: Raptorex kriegsteini. Sereno, P., Tan L., Brusatte, S. L., Kriegstein, H. J., Zhao X.-J., Cloward, K. 2009. Tyrannosaurid … Continue reading
