Even Tyrannosaurus rex needs an arch-nemesis with whom he can vie for dominance of the Cretaceous jungle. And who better to challenge him than another giant flesh-eating dinosaur?
I just read on Twitter that a paleontologist named Robert Detrich is working on a newly discovered giant oviraptorosaur from the same time and place as T. Rex itself. This new dinosaur's tibia alone has a length of 88.9 cm (35 inches). Whether or not it would have antagonized T. Rex remains to be seen, but I always felt the Tyrant King needed a competitor from the same time and place with whom he could fight.
