Stegosaurus is one of the most elaborately-ornamented dinosaurs. This Jurassic herbivore is decked with 17 broad bony plates from its neck down its back, with the tip of its tail bearing four long spikes. When threatened, Stegosaurus will turn its head back to look over its shoulder, to better aim the swing of its dangerous tail.
