info on a tyrannosaurus rex?

Question

can any1 give me lots of info on a tyrannosaurus rex.

Answer 1

Tyrannosaurus, name of a genus (group) of large, two-legged, meat-eating dinosaurs that lived in the late Cretaceous Period, about 65 million years ago. The name Tyrannosaurus is derived from the Greek words tyrannos, “tyrant,” and sauros, “lizard.” Instantly recognizable by their size, upright posture, serrated (jagged) teeth, and small, two-fingered forelimbs, Tyrannosaurus were some of the largest meat-eating land animals that ever existed.

Scientists know more about Tyrannosaurus than they do about any other predatory dinosaur. They have found dozens of skeletons of these giant saurischians (“lizard-hipped” dinosaurs) in Mongolia and throughout the western United States and Canada. A particularly large and complete skeleton named Sue is on display at the Field Museum in Chicago. Another fossilized Tyrannosaurus, discovered in Montana, was so well preserved that blood vessels and other soft tissue remained within its thighbone.

Tyrannosaurus are members of the family Tyrannosauridae, in the suborder Theropoda. Although scientists disagree about the number of species in the genus Tyrannosaurus, some scientists recognize four species, of which Tyrannosaurus rex is the best known.

Tyrannosaurus were among the largest flesh-eating terrestrial animals, exceeded in size only by Giganotosaurus and Carcharodontosaurus. Mapusaurus and Spinosaurus may also have been larger than Tyrannosaurus. Tyrannosaurus reached 12.5 m (41 ft) in length and 5 m (16 ft) in height, and weighed more than 5 metric tons. The skull of a Tyrannosaurus was large and flexible and contained a brain comparable in size to those of modern reptiles. Its bone-crushing bite was probably more powerful than that of any other flesh-eating dinosaur. The bridge of the nose contained wartlike knobs and pits. The animals had a broad field of vision but could focus their eyes directly to the front. A Tyrannosaurus had short arms with few nerves running through them. This limited nerve development suggests that the arm movements must have been unwieldy and clumsy. The barrel-shaped chest of these dinosaurs indicates that the lungs were very large. A latticework of bones protected the stomach and other internal organs. The legs were long and slender.

Tyrannosaurus probably preferred open terrain, such as broad game trails and open forests, where it could move its large body and see unimpeded by brush. Scientists estimate that Tyrannosaurus could walk rapidly and may have been able to run at speeds up to 40 km/h (25 mph) when chasing prey. They also could lie in ambush upon a strong pelvic extension, with chin on the ground, watching for prey with their high-placed eyes.

Scientists debate whether Tyrannosaurus were warm-blooded like modern mammals. Evidence suggests that the creatures had a uniform body temperature, which would require a metabolic rate higher than that of other reptiles. Some scientists have even suggested that Tyrannosaurus had feathers, not for flying but for insulation.

A higher body temperature would require Tyrannosaurus to eat more often than other reptiles. The stomach of the dinosaur could hold more than half a metric ton of flesh, which would be consumed every few weeks. Scientists have found a 2-liter (2.1-qt) lump of fossilized dung that contains direct evidence of the prey of Tyrannosaurus: partly digested bone fragments of young plant-eating dinosaurs. Further evidence of their diet includes a Triceratops pelvis that exhibits deep punctures and grooves made by Tyrannosaurus teeth. Like most active carnivores, Tyrannosaurus probably also fed on the decaying bodies of dinosaurs killed by starvation and floods. Tooth marks on some Tyrannosaurus skulls indicate that the animals fought with one another by biting on the face.

Answer 2

Tyrannosaurus (meaning 'tyrant lizard') is the most famous dinosaur genus and a fixture in popular culture. Known colloquially as T. rex, the species Tyrannosaurus rex hails from what is now western North America. Some scientists consider the slightly older Tarbosaurus bataar from Asia to represent a second species of Tyrannosaurus, while others maintain Tarbosaurus as a separate genus.

Like other tyrannosaurid theropods, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, and retained only two digits. Although other theropods rivaled or exceeded T. rex in size, it was the largest known tyrannosaurid and one of the largest known land predators, measuring over 12 meters (40 feet) in length and weighing as much as an elephant.

Fossils of T. rex have been found in North American rock formations dating to the very end of the Cretaceous Period; it was among the last dinosaurs to exist prior to the Cretaceous-Tertiary extinction event. More than 30 specimens of T. rex have now been identified, some nearly complete, which has allowed significant research into many aspects of its biology, including its life history and biomechanics. The feeding habits and potential speed of T. rex remain controversial.

Answer 3

If you had a T rex for a pet, no mailman would ever deliver letters to your home. you get the picture, don't you? Hey, we are not paleontologists here. just look it up in wikipedia.

Answer 4

Well they were very large carnivores. Although they had small arms its said that because of their small size they werent of much use. They also had very powerful leg muscles which allowed them to run at relatively fast speeds.
