The Stegosaurus (pronounced STEG-o-soar-US) had many plates on it's back, they may have been use for protection or to control it's body temperature. This dinosaur also has 4 spikes on it's tail used to defend against predators. These bony spikes could leave another dino really wounded. Even though It had many dangerous aspects to it, Stegosaurus was a friendly dinosaur.
Stegosaurus was also 30 feet long and 14 feet tall, and It weighed 5+ tons!
It had a beak for a mouth with 0 teeth, too. Stegosaurus is also known to have two brains, though now we know this is false.
That is most of the information that we know about the Stegosaurus, thanks for visiting TDT! :D
