Lesson 3: eating: teeth and jaws tell us a lot about what they used to eat, carnivores: sharp teeth, sharp claws, herbivores: flat teeth, omnivores: mixture of sharp and flat teeth. Jaw of hadrasaur- wide flat jaw excellent for grinding plant material, the teeth are layered on top of eachother. They also had many more replacement teeth growing beneath the working tooth. Each tooth is tightly packed together, allowing for on large grinding surface in each upper or lower jaw: dental battery- large set of teeth. Great example of convergent evolution: triceratops and the hardrosaur corythosaurus are the 2 animals that have batteries. dental batteries, however, both of these groups evolve this feature independently because their older ancestors didn"t have massive tooth. Diplodocus: tyrannosaur tooh- serrated knife-like edge, gigantosaurus tooth- long root. They would use their strong arms: some of the strangest arms of any theropod dinosaur are those in the.
