Due to the striking spikes on its tail and back plates, the Stegosaurus is one of best-known dinosaurs.
With its interesting, prominent features, the Stegosaurus was a herbivore with plates on its back, a spiked tail, small head and long legs. With seventeen plates and spikes measuring about 30 centimetres in length, this dinosaur was always ready to defend itself. Measuring ten metres in length, the Stegosaurus had a brain no bigger than a walnut. Its hind legs were twice as long as its front ones.
