A number of recent paleontological discoveries have cemented Tyrannosaurus rex as the black sheep of the Tyrannosaurus genus. Seems that the rest of his relatives were much smaller.
Well, except for Tarbosaurus, but we don’t talk to them after what they said about our Bistahieversor at our Kileskus’ wedding the year before last.
The amount of information that we know about T. rex has expanded in the last decade, and no doubt a lot of that movement can be blamed in some way on Jurassic Park.
Almost all of the tyrannosaurus discovered were relatively small, like Kileskus and Guanlong, who had a lovely bony ridge on its snout. Raptorex had basically the same body plan as rex, but was only the size of a horse. Dilong even had feathers, something that might actually make it more like rex than not.
Wired has the full article, with more pictures and also this tidbit: T. rex reached its enormous size in an only thirty year lifespan.
