Athough we know that to be false, we still don't know what the plates were used for. We do know Stegosaurus was a 30 foot long herbivore that lived during the late Jurassic period. Stegosaurus had 17 plates on its back.The plates were in two rows on its back, but they were not symmetrical. One plate would be on the left side, and the plate on the right would be somewhat behind it, and the next plate on the left would be behind that.though we know that to be false, we still don't know what the plates were used for.
