About it

Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T. 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. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids, and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.

In the game

In Bart's second game, he was seen in Willie's mind where he was with his back behind Bart. When he heared a noise, he turned and Bart could have a clear shot with his slingshot and shot a pill at the monster's throat when he became a little T-rex.



  • The T-rex was big and all in orange.
  • When the small T-rex growled it was heard like a duck quack.
