Image Gallery: Plant-eating dinosaur teeth and jaws

Which dinosaurs chewed their food and which didn't? Take a look at some plant-eating dinosaurs' teeth and jaws, as well as gastroliths (stomach stones), to see how they might have eaten their food - raking and slicing before using stones in their stomachs to break food up, or grinding their back teeth side-to-side.
