The Tyrannosaurus lived from the Late Cretaceous at the end of the Mesozoic Era. As with most Dinosaurs, the Tyrannosaurus was hatched from an egg. The Tyrannosaurus's skin was bumpy, like an alligator's skin. The T-rex was a relatively smart dinosaur. Its brain was larger than most other dinosaurs, even though it was smaller compared to his body mass. |
