The Stegosaurus is easy to spot from afar, and not only because it's so huge: the fiery red double row of boney curved armored plates on its back is unmistakable. It forms a beautiful contrast to its yellowish lizard skin. With its head lowered, it trudges across the meadows, always holding its long tail up a little. Its favorite thing to do is graze. That's what a Stegosaurus does all day long because it takes a while for the 4.5-ton herbivore to eat enough to keep going. Fancy a munch?
