OMG, there is a dinosaur here! Don't worry - it's not a predator - this one eats only plants. Dinosaurs became vegetarians before it became mainstream. Some of the most commonly known plant eaters are Stegosaurus, Triceratops, Brachiosaurus, Diplodocus, and Ankylosaurus. These plant-eating dinosaurs had to eat a lot of plants each day. One of the most famous plant-eating dinosaurs is the Apatosaurus or the Brontosaurus - it is right in front of you in our VSCO Girl Dinosaur and Rawr.
