"Terrifying Chainsaw-Like Teeth of Ancient Sea-Creature Helicoprion Unearthed"
The Helicoprion, an ancient sea creature that lived 270 million years ago, possessed a terrifying set of spiral-shaped teeth resembling a chainsaw. For decades, paleontologists struggled to determine the creature's identity and the location of its teeth. It was eventually discovered that the Helicoprion was a cartilaginous eugeneodont fish, not a shark, and its teeth were located in the middle of its mouth. Experts believe the dental structure was used to saw through prey or remove shells from cephalopods.
