The stegosaurus lived 84 million year before the T. Rex

The Stegosaurus and the Tyrannosaurus rex are some of the most recognizable dinosaurs for the general public and are often depicted together in popular media. However the Stegosaurus became extinct long before the Tyrannosaurus rex existed. The Stegosaurus was a herbivore that roamed what eventually became part of North America during the Late Jurassic period, around 150 million years ago. It had massive armored plates along its spine and a distinctive spiked tail. The Tyrannosaurus rex lived in roughly the same area of the world, but from 68 to 66 million years ago, during the Cretaceous period. A fearsome predator, a Tyrannosaurus rex could be around 40 feet long, and was probably one of the largest land carnivores of all time.
