The Tenacious Tyrant T­Rex
By: Joshua Teller Hi, come with me while I take you into the world of the T­Rex. I’m going to teach you all about the amazing T­Rex. I only have one question for you. Are you ready to meet the lizard king?
What is the T­Rex? Tyrannosaurus rex means “tyrant lizard king.” It is 40 feet long,15­20 feet tall and weighs 5­7 tons! It was a carnivore. Carnivore means meat eater. It lived in the cretaceous period. The cretaceous period was 65.5 million years ago. It had a 5 foot scull. All about the T­Rex running It is hard to tell how fast they ran because they lived so long ago. So, all we know is that they ran no more than 20 mph. If they fell while running their arms wouldn’t break their fall because there arms are too short.​
​
They would seriously injure themselves. Their stride was about 1.78 meters long How did they become extinct? Almost 66 million years ago an asteroid that was about 4­6 miles in diameter collided with the earth and killed all sorts of animals including the T­Rex. It also could have caused tsunamis, tornados, thunderstorms, rain and hail. That’s one heck of an asteroid! What did it eat and how did it get it’s food? It ate the Edmontosaurus, Anatosaurus, Triceratops and other dinosaurs. Also, they sometimes even ate each other! It used it’s big and strong tail, it’s teeth and it’s size. How did the T­Rex defend itself? It’s huge teeth were a very good source of defence. Imagine 12,800 lbs crushing you! Each T­Rex had 50­60 teeth in its mouth at one time. Each tooth is about 9 inches long. If one tooth fell out another one would just grow back quickly. Its jaw was about 4 feet long! So, overall the T­Rex could defend itself very well. Wow, how about that? Isn’t the T­Rex cool? Can you imagine being face to face with a real T­Rex? If not, now you can! Look at the next page!!!!
