TYRANNOSAURUS REX By: Adeeb Hassan

Tyrannosaurus rex One of the largest dinosaurs that ever lived Tyrannosaurus rex was a fierce carnivore. Scientists believe this powerful predator could eat up to 500 pounds.And they can eat 230 kilograms of meat in one bite. Fossils of T. rex prey, including Triceratops and Edmontosaurus, suggest Tyrannosaurus crushed and broke bones as it ate. http://animals.nationalgeographic.com/animals/enlarge/tyrannosaurus.html

About Tyrannosaurus rex Family The Tyrannosaurus family, of which the most famous species is T. rex, were among the last dinosaurs to appear on the planet, around 80m years ago. These large carnivorous theropods were only on the planet for a relatively short time, but they had a huge impact on our understanding of dinosaurs - partly because more specimens exist from these final stages than any earlier time in history. http://images.google.com/imgres?imgurl=http://static.guim.co.uk/sys-images

Where did it live? The Tyrannosaurus Rex roamed North America and Asia.There have been 24 good skeletons, of the T.Rex, found in the world. There is no evidence that the T.Rex took care of their babies. The babies were very helpless after birth. There are many theories about how the dinosaurs died. One is that an asteroid hit earth and blocked out the sun. That caused the plants to die and that made the plant-eaters die. The T.Rex died because there were no plant-eaters left to eat. http://www.alvord.k12.ca.us/programs/Gate/Gate_Academy/Matt%20T-Rex.htm

WHAT DID THE T.REX EAT? The T.Rex eats other dinosaurs, like the Stegasaurus, Triceratops, Iguanodon, and many others. It is the "KING CARNIVORE" of all dinosaurs. It uses its big, sharp teeth to rip its prey open http://www.alvord.k12.ca.us/programs/Gate/Gate_Academy/Matt%20T-Rex.htm

WHAT WAS T.REX'S HEIGHT AND WEIGHT? The T.Rex was about 20 feet tall, the height of a two story building.He weighed around 15 tons. That's the weight of 7 1/2 elephants. Tyrannosaurus Rex means "Tyrant of Lizards" because the T.Rex was a tyrant to the dinosaurs. http://www.alvord.k12.ca.us/programs/Gate/Gate_Academy/Matt%20T-Rex.htm

Masiakasaurus Located more than 500 miles off the southeastern coast of Africa, Madagascar is well known for being home to some of the most unusual animals on Earth. And apparently that rule was no different during the age of the dinosaurs. 70 million years ago, Madagascar was inhabited by such weirdos as pug-nosed, land-dwelling, plant-eating crocodiles, flying raptors, giant, thick-skulled carnivorous dinosaurs, and one small carnivorous dinosaur that would make anyone today glad that braces and retainers were invented; Masiakasaurus. http://www.computerpro.com/~sarah/Masiakasaurus_Fact_File.html

About Masiakasaurus Masiakasaurus was a very strange looking dinosaur from Madagascar.. It had a long neck and tail, walked on two feet, and weighed about as much as a German shepherd, but is most unique characteristics is its front teeth.  They stuck almost straight out from the front of its mouth. This dental feature has been found on some flying reptiles, but this is the first time that it has been found on a dinosaur. http://images.google.com/imgres?imgurl=http://www.dinosaur-world.com/weird_dinosaurs/species

What does Masiakasaurus Eat? The Masiakasaurus eats Fish, lizards snakes, and small mammals. http://images.google.com/imgres?imgurl=http://www.computerpro.com/

Information This strange adaptation, which evolved separately in Pterosaurs and Masiakasaurus, is an example of a process known as convergent evolution. And since the pterosaurs with this type of dentition were fish-eaters that prevented their slippery prey from wriggling out of their mouths by impaling them on their teeth, Masiakasaurus likely used its teeth to catch fish as well. http://images.google.com/imgres?imgurl=http://www.computerpro.com/
