Rexes are draconic dinosaurs who inhabit Dinosaur Land, first appearing in Super Mario World from Super Mario universe.


They have purplish bodies with single nasal horns and large fangs, which could imply them to be carnivores. Even though they have a pair of wings, they can't fly, as those are too small to lift them off the ground. Their physical appearance and overall shape suggests they share a common ancestor with the Yoshi.
