"Suppose you found the bones of an unidentified animal. How could you learn about what the animal ate? What specific structures would give you clues about the creature's diet?"
If you were to find the bones of an unidentified animal, your first thought probably wouldn't be, "I wonder what this animal ate when it lived among us in space and time." But lets pretend that this was your first thought regarding the animal. How would you find the answer to the question? Well, you would look at the teeth. What kinds of teeth are among the bones? If they are mostly molars and premolars, then that would mean that the animal generally ate a diet which would require it to grind and crush the food in it's mouth.
A good example of this sort of animal is the horse. The horse's diet is made up of foods such as oats, grass, grain, and hay. All of these require the horse to grind and crush the food using it's molars.
Likewise, if the animal's teeth are mainly incisors and canines the animal was probably be a flesh eating, ferocious best from the underworld. Either that, or it could be a harmless little chihuahua that generally wore little booties and doggy dresses...both work I suppose. My point is that incisors and canines are characteristics of meat-eaters.
This is one of the fascinating ways that you can identify an animal's diet.
