Small teeth for a Big Job:
Triceratops ate plants -- lots of them -- using its sharp beak to nip off vegetation and a set of continuously replaced teeth to chew tough, fibrous food.
Each tooth was small, and they grew in stacks. The stacks formed long rows in the upper and lower jaws and created large cutting surfaces for crushing and slicing food. Teeth dropped out constantly, so the cutting edges always stayed sharp. |
