Tyrannosaurus

Dinosaurs are a big part of our history. They lived on the earth much earlier before human beings. Millions of years ago, great beasts called "dinosaurs” wandered over the earth.

There were different types of dinosaurs, some were big, some were small; some ate plants, some ate meat; some lived on the land, some lived in the water, and some flied in the sky. I am very fond of Tyrannosaurus, a huge meat-eating dinosaur. When I was a little boy, the most powerful image on TV is a giant dinosaur. It was the king of the dinosaur world. It looked very cool, even though it sometimes bullied others.

The most famous in the family is T. rex, they are among the last dinosaurs on the planet, around 80 million years ago. Their bones were hollow, like a bird’s bones. It had pointed teeth to rip meat. They were 40 feet long, about 20 feet tall. T-Rex had a huge head. They had tiny arms, only three feet long. There were two fingers on each arm. But their legs were strong and powerful. Each foot had three large toes. T-rex had a big and strong tail for balance, which helped a lot make quick turns while running. Some people think it can run very fast. But some scientists recently estimated it was not a fast runner. T-Rex was one of the biggest of the meat-eating dinosaurs who could eat other dinosaurs. They weighed 5 to 7 tons. Scientists believe it could eat up to 500 pounds. We don't yet know for sure, but there is good reason to believe that female T. Rex outweighed their males.

They lived in the United States, in Canada and in Asia. T-Rex was one the last of the dinosaurs on the earth. At that time, the weather was warmer. The sea level was much higher. We do not know why T-rex disappeared from our earth. It is still a mystery.
