5. Helicoprion: The Buzzsaw Killer
Helicoprion was an intriguing ancient marine creature that earned the nickname “Buzzsaw Killer” due to its unique feature. It looked like a shark and had a lower jaw with a tooth whirl, similar to a circular saw.
Measuring up to 35 feet long, Helicoprion was even larger than the biggest known great white sharks. Despite its impressive set of teeth, Helicoprion is classified as a chimera, which is a type of cartilaginous fish. This sets it apart from typical sharks and adds to the mystery and fascination surrounding this fascinating prehistoric predator.
