Dinosaur
The largest dinosaurs were herbivores (plant-eaters), such as Apatosaurus and Brachiosaurus. They were the largest animals to ever walk on dry land. Other plant-eaters, such as Iguanodon, had special weapons to help them fight off the meat-eaters. For example, Triceratops had three horns on its head shield, Ankylosaurus was covered in boney plates, and Stegosaurus had spikes on its tail.
