Tyrannosaurus

Up Tyrannosaurus was a genus of theropod dinosaurs, containing Tyrannosaurus rex, probably the most well known dinosaur species in the world. Tyrannosaurus fossils have been found that date from68-65 million years ago, where they lived in what is now known as the west of North America. Tyrannosaurus are from the dinosaur order Saurischia, the suborder Theropoda, the superfamily Tyrannosauroidea, the family Tyrannosauridae, and the subfamily Tyrannosaufinae. Tyrannosaurus was a bipedal carnivore, with a huge skull and a heavy long tail. Tyrannosaurus rex is the best known and most studied member of this genus, measuring up to 13 metres in length, 4 metres tall, and weighing up to 6.8 metric tons. As the largest carnivore in its environment, the T.rex would have been one of the most dangerous and impressive animals during the last three million years of the Cretaceous Period.

More than 30 different species of Tyrannosaurus rex have been identified, from almost complete animal skeletons to small bone and tissue fragments. Along with its large and impressive stature, it is the range and scope of different fossil materials that have made this dinosaur so well studied and known. While a number of issues relating to its diet, speed, and physiology are still debated among scientists, more is known about the Tyrannosaurus than probably any other dinosaur. The largest known Tyrannosaurus rex skulls measure up to 1.5 metres in length, and feature the same style openings in the skull that are a feature of all carnivorous theropods. Its skull, however, differs from other theropods, with a wide rear and a very narrow snout which allow for unusually good binocular vision.

Like a lot of bipedal dinosaurs, the Tyrannosorous has historically been mistakenly depicted with a body at 45 degrees, where it was depicted much like a kangaroo. This has been remedied in recent years however, and most modern films and museums correctly depict the animals with their body roughly parallel to the ground. The eating habits of the Tyrannosaurus are another area where public perception may be different from reality, and there is still a lot of debate over whether the Tyrannosaurus was a predator or a pure scavenger. The Tyrannosaurus rex is probably the most well recognised dinosaur on the planet, and its appearance in a number of separate popular cultural mediums has helped to raise the profile of dinosaurs all over the world.
