Hadrosaurs had the most spectacular array of teeth of any plant-eating dinosaur. Hundreds of sharp, diamond-shaped, grinding teeth lined both sides of its jaw. The teeth were set way back in the jaw, which left the broad beak toothless. The grinding surface formed by these teeth acted like a vegetable grater to shred the plants. New teeth constantly grew to replace the worn ones.
