Tyrannosaurus

What would be the best title for the passage below?

One of the most dangerous dinosaurs was the Tyrannosaurus rex. It looked like a huge lizard with sharp teeth. It lived over 60 million years ago. From nose to tail, T-rex was as long as a school bus. It was taller than a house. It weighed more than an airplane. T-rex’s head was as long as a kitchen table. T-rex was one of the biggest meat-eating dinosaurs. It could eat hundreds of pounds of meat in one bite. Animals that eat meat have sharp teeth. T-rex had 60 of them! Some of the teeth were as big as bananas. When T-rex lost a tooth, it grew a new one. T-rex stood on two powerful legs. It also had two small arms. Its strong tail helped keep it from falling over. It might be fun to see a live Tyrannosaurus rex, but I wouldn’t want to meet one. Would you?
