Tyrannosaurus Rex

The Tyrannosaurus Rex lived in North America. It grew to be about 40 feet long (12 meters) and it’s thought to have weighed over 12,000 pounds (6,000 kilos). Take a look at these pictures. What do you notice?


It had short arms, but powerful legs, tail, and jaw. It was a meat-eater, a carnivore and could eat other large animals. 

Similar to birds, they had holes, air sacs, in their bones to make them lighter. This is seen in the head of the T-Rex. It’s head was so huge that it had to be lighter to be able to hold it up.
