Tyrannosaurus Rex was a large carnivorous dinosaur that shook the Earth during the Late Cretaceous, 67–66Ma. It mainly fed on Triceratops and edmontosaurus.The largest Tyrannosaurus Rex ever excavated measured 12.3 metres (40 ft) long and 4 metres (13 ft) tall at the hips.I believe this is nature's ultimate carnivore,even though some Theropods are larger,Tyrannosaurus Rex has very strong jaw and serrated teeth.Spinosaurus,while large has a very large spine that is vulnerable to falling and would immobilize it, effectively kill it eventually.
Tyrannosaurus Rex is king of the dinosaurs!
