Stegosaurus & T-Rex were never together.

You know when you see dinosaur movies? and you see these two together....just walking around in the same clear piece of land? Turns out...that this is historically inaccurate. The Stegosaurus and T-Rex never existed in the same time period. Infact, their existence is separated by 33 million years. So we can add this to the list of things that Hollywood does not base on facts.
