Story: Dolphins

Fossilised teeth (2nd of 2)

Fossilised teeth

The teeth of the shark-toothed dolphin were very different from those of modern dolphins, which are all simple conical teeth more suitable for grasping than for chewing. The teeth of this more ancient dolphin are strongly differentiated, with cone-shaped incisors at the front of the jaw and more complex teeth at the back.
