Tyrannosaurus rex was a fierce predator that walked on two powerful legs. This meat-eater had a huge head with large, pointed, replaceable teeth and well-developed jaw muscles. It had tiny arms, each with two fingers. Each bird-like foot had three large toes, all equipped with claws. http://www.enchantedlearning.com/subjects/dinosaurs/dinos/Trex.shtml

Size: Tyrannosaurus rex was up to 40 feet (12.4 m) long, about 15 to 20 feet (4.6 to 6 m) tall.The arms were only about 3 feet (1 m) long. Tyrannosaurus rex was roughly 5 to 7 tons in weight. http://www.enchantedlearning.com/subjects/dinosaurs/dinos/Trex.shtml

Diet: T. rex was a meat-eater and was at the top of the food chain in its environment. It probably chased its prey and took huge bites of their flesh, mortally wounded the prey, then devoured it. Its huge jaws and powerful, clawed legs were its lethal weapons. T. rex's tiny arms may not have played much of a part in the kill. http://www.enchantedlearning.com/subjects/dinosaurs/dinos/trex/Trexdiet.shtml

Population: T. rex went extinct during the K-T mass extinction, about 65 million years ago. This extinction killed the remaining dinosaurs (not just T. rex) and many other animal and plant groups. http://www.enchantedlearning.com/subjects/dinosaurs/dinos/trex/Trexextinct.shtml
