What it looked like
Tyrannosaurus rex was a fierce predator that walked on two powerful legs in forests. This meat-eater had a huge head with large, pointed teeth and well-developed jaw muscles. It had tiny arms, each with two fingers. Each bird-like foot had three large toes, all with claws. T. rex had a stiff, pointed tail that provided balance and helped it to make quick turns while running. Fossilized pieces of its rough, scaly skin have been found. It was bumpy, like an alligator's skin

What it ate
Tyrannosaurus was a meat-eating dinosaur with big zig-zag teeth that ripped through flesh. It lived on other smaller dinosaurs that it attacked, or it frightened other attackers away from their kill.

How it moved around
Tyrannosaurus moved on its back two feet, and could run very fast. Because of its tail, which helped it to balance, it could turn very quickly while chasing its prey.

How it probably behaved
Tyrannosaurus was a fierce killer, and could probably have swallowed human beings whole if it was around today!
