If you heard that a stegosaurus had two brains that is not a real fact!!!
People used to think that a stegosrous had one brain in its head and one brain in is tail but now scientists think they were wrong about that. Nowdays people just think that a steggy only had one brain in its head and the thing in its tail was another type of organ that wasn't a brain that was used for storing up gylogen. So stegos werent the genious of the dinosuar world after all lol!!!! Also dinosuars brains were the size of a walnut. So now you know the truth about the stegosaurus and its single brain so help spread the truth!!!!
