Tyrannosaurus was a genus of theropod dinosaur that lived in what is now the western border regions of the U.S. and Canada at the very end of the Cretaceous Period. The East Asian cousin Tarbosaurus is sometimes considered to be the same as Tyrannosaurus, but this is still debated. The species Tyrannosaurus rex, commonly abbreviated to T. rex, is one of the dinosaurs most often featured in popular culture around the world.
