Helicoprion was a long-lived genus of extinct, shark-like eugeoneodontid holocephalid fish. Helicoprion lived from the late Carboniferous period to the Early Triassic. It is commonly known for its strange teeth that were arranged in a  "tooth whorl". It is estimated to grow 10-15 ft (3-4m) in length.

  • The model that is seen in Jurassic Park: Builder is actually inaccurate. Recent studies show the fearsome teeth were built more like a saw instead of hanging outside of the mouth. The model in Jurassic World: The Game has a more accurate jaw.
