When you are long gone and buried, some of the last things that remain are your teeth. Teeth have to be hard and long-lasting because they do a tough job.
Think about your teeth. Look at them in a mirror. You probably know you have different teeth for different jobs. The front ones (incisors) are like chisels and designed to cut. The back ones (molars) are broad and bumpy and designed to crush.
Now look at this dino's teeth.
