New T. Rex-like Dinosaur Discovered
The discovery of a new dinosaur species, Raptorex kriegsteini, has shed new light on the evolution of the mighty Tyrannosaurus rex. Both share distinctive features: strong back legs, tiny forelimbs, dagger-like teeth, a whip-like tail, and a disproportionately large head. But, the difference is size. The new discovery stood only 9 feet tall. It was thought that these signature T. rex features evolved as a consequence of its large size, so finding these same feature in a smaller package changes the way scientists look at T. rex.
