T-rex

T-rex is a favorite around the world. Trex is the 2nd biggest meat-eating dinosaur. It was 40 feet (12 m) long and estimated to weigh 5-6 tons. T-rex is so popular it was in my favorite movies Jurassic Park. Its nick name is tyrant king lizard and I can see why! hard to believe that its teeth can be as longs bananas! Scientist are not sure what T-rex's arms were used for but I read in some books that it may have helped it while lying on the ground push its self off the ground. T-rex could not have run super fast because of its weight, but it may have ran about 20-25 mils per hour. T-rex was an ambusher. It would hide and wait for a little then at the right moment and when it selected its prey it would charge at surprised prey. Then the chase was on! It would clamp down on its victim with banana sized teeth and hold it until the prey was tired out and died. Then it would eat. It did prey on duck-biled dinosaurs like Maiasaura and ceratosians like triceratops(let triceratops win). T-rex lived in the late Certaceous. T-rex had a long tail to balance its body weight. Sue the T-rex is the most complete skeleton of any T-rex.I read about Sue but I can't remember it but I do Know that it was found by a paleontologist named Sue and her pet dog. T-rex is one interesting animal!
