T. REX IS a celebrity character—the nightmare haunter—but it was also a real animal. Paleontologists know quite a lot about it: what it looked like, how it moved and breathed and sensed its world, what it ate, how it grew, and why it was able to get so big. In part, that’s because we have a lot of fossils: over fifty skeletons, some nearly complete, more than for almost any other dinosaur.
