TYRANNOSAURUS REX

(T. rex )

Tyrannosaurus, meaning (‘tyrant lizard’), is a genus of theropod dinosaur. The famous species Tyrannosaurus rex (‘rex’ meaning ‘king’ in Latin), commonly abbreviate to T. rex, is a fixture in popular culture around the world.

Like other tyrannosurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hind limbs, Tyrannosaurus fore limbs were small. Although other theropods rivaled or exceeded T.rex in size. By far the largest carnivore in its environment,

More than 30 specimens of T. rex have been identified, some of which are nearly complete skeletons. Tyrannosaurus rex was one of the largest land carnivores of all time, measuring 12,8 metres (42 feet) long, and ws 4,0 metres (13 feet) tall at the hips. Although Tyrannosaurus rex was larger than the well known Jurassic theropod Allosaurus, it was slightly smaller than Cretaceous carnivores Spinosaurus and Giganotosaurus.

The neck of T. rex formed a natural shaped curve like that of other theropod, but was short and mascular to support the massive head. The fore limbs had only two clawed fingers. The tail was heavy and long, sometimes containing over fortyvertebrate, in order to balance the massive head and torso.

The largest known T. rex skulls measure up to 5 feet (1, 5 meters) in length. The teeth of T. rex displayed marked (differences in shape). The teeth at the front of the upper jaw were closely packed. The largest found so far is estimated to have been 30 centimetres long including the root when the animal was alive, making the largest tooth of any carnivorous dinosaur.
