The skeletons of ancient animals, like this roaring Gorgonopsid seen on Your Inner Fish, can tell detailed stories about our own evolution history. They may look like dinosaurs, but Gorgonopsids were actually the ancestors of mammals. Their ferocious teeth were specialized for different tasks—pointy teeth for piercing, angled teeth for tearing, and flat teeth for chewing—unlike reptiles and dinosaurs which had many similar copies of the same tooth shape, unspecialized for different tasks. Gorgonopsids could chew and digest food much more efficiently, laying down the precursors to the molars we have in our mouths today.
