Scientific Understanding of T.Rex Revised by a Decade of New Research and Discovery

AdultTyrannosaurus

We’ve all heard this story: the Late Cretaceous of Asia and North America—about 65 million years ago—was dominated by several large-headed, bipedal predatory dinosaurs like Tyrannosaurus rex and Tarbosaurus that had tiny arms. But a decade of new fossil discoveries that have more than doubled the number of known tyrannosaur species has changed this tale.
