TYRANOSAURUS REX (ty-RAN-o-sawr-us) "Tyrant Lizard" (Greek tyrannos = tyrant + sauros = lizard, because of its great size and wicked TEETH and CLAWS)

The last and largest known CARNOSAUR. This huge meat eater measured up to 50 feet (15 m) from the tip of its enormous jaws to the end of its TAIL. It was 18.5 feet (5.6 m) tall and weighed 6 tons (5.4 metric tons). It ran with its massive tail extended to balance its 4 foot (1.2 m) head. Its monstrous 3 foot (90 cm) jaws were lined with 60 dagger-like teeth that were 3 to 6 inches (8 to 15 cm) long. Tyrannosaurus had long, strong hind legs, and its huge FEET were equipped with 8 inch (20 cm)talons. However, its arms were very short, only about 30 inches (76 cm) long they were so short that Tyranosaurus could not even scratch its chin! But the HANDS, like the feet, were armed with long, strong claws.

This ferocious BIPEDAL dinosaur stalked its prey across western North America during Late Cretaceous times. It probably preferred to eat young duckbills or other prey that was easy to catch. Due to some controversy some Paleontologists think that the Tyranosaurus was to have not been a hunter, but a scavenger. They scavenged off other predator's kills, using their sheer size to overpower their opponent's so the Tyranosaurus could steal its kill. Though if there was no fresh kills lying around the theory about Tyrannosaurus hunting its prey comes true. So In short both theories are true. Seven complete skeletons have been found in Montana. Its FOSSILS have also been found in Wyoming, New Mexico, and South Dakota. A close relative, TARBOSAURUS, lived in Mongolia.
