Tyrannosaurus
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex is one of the most well-represented of the large theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Most paleontologists today accept that Tyrannosaurus was both an active predator and a scavenger.
