There was a Brand once upon a time

A Stegosaurus was a large, plant-eating dinosaur from the Late Jurassic, famous for its distinctive double row of bony plates along its back and four long spikes on its tail, used for defense against predators like Allosaurus, with a small head, tiny brain (about the size of a bent hotdog), and powerful hind legs making its back arched, while its plates likely aided in display or temperature regulation.
