Tyrannosaurus

 

a genus of gigantic carnivorous dinosaurs of the superfamily Carnosauria. The tyrannosaur, which reached lengths of 15 m and more and stood more than 6 m tall on its hind legs, was the largest terrestrial predator in history. It had a massive skull (up to 1.5 m in length) and powerful daggerlike teeth. Its strong hind legs and powerful tail helped support the body, while its forelimbs were reduced to short appendages. The tyrannosaur was one of the last dinosaurs to live on the earth. Its remains have been discovered in Upper Cretaceous deposits of North America. The tyrannosaur was related to the tarbosaur.
