And Tyrannosaurus was the weirdest. http://archosaurmusings.wordpress.com/2011/10/19/guest-post-love-the-tyrant-not-the-hype/
I don't understand the article completely, as I'm not a vertebratologist and don't know the morphology very well. But it's clear that T. rex was a very unusual theropod for a whole bunch of reasons.
I really love this article because instead of mythologizing the animals, the author describes Tyrannosarids as if they were still alive, breathing, moving giant predators.
Neat stuff, thanks, Kai.
Awesome.
It paints a picture of T. rex being a multi-ton ninja with a face full of sharp death.
