Tyrannosaurus

Tyrannosaurus was a Carnivore from the Late Cretaceous Period - not from Jurrasic, as you may have thought.

Tyrannosaurus

Tyrannosaurus meaning 'tyrant lizard' is a genus of tyrannosaurid theropod dinosaur. The species Tyrannosaurus rex, commonly abbreviated to T. rex, is one of the dinosaurs most often featured in popular culture around the world. It comes from what is now western North America. Like other tyrannosaurids, 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 metres (40 feet) in length and up to 7.5 tons in weight.

In 1993 a rival to T-rex was discovered in Argentina, which was approximately 50% larger, and had sharper teeth - Gigantosaurus !
