A partial skull once believed to be from a T. rex is a newfound species, a study revealed. T. mcraeensis could shed light on why tyrannosaurs evolved into giants.

Mounted skeletons of different age groups, Los Angeles Natural History Museum. The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have ...
Hendrickson's discovery proved to be historic. As diggers uncovered more and more bones, they realized Sue represented the largest and most complete specimen of a Tyrannosaurus rex ever found.
