Not Sharks or Dinosaurs: The Tiny Ancient Creature With Earth’s Sharpest Teeth

Tiny marine creatures called conodonts, extinct for millions of years, held the title for the sharpest teeth. These eel-like animals had microscopic teeth far sharper than those of T. rex or Megalodon. New research reveals their incredible evolutionary adaptation for feeding. Conodonts were not giants but biological innovators with a unique record of early vertebrate evolution.
