Trivia

 * Helicoprion is Greek for 'Spiral Saw'.
 * Helicoprion existed around 290 million years ago, swimming the ancient seas of what would later become the Mid-Western United States.
 * Helicoprion was also featured in Jurassic Park Builder, but it had a different design than the Jurassic World iteration. In Jurassic Park Builder, the tooth whorl was featured spiraling out of the sharks mouth and downwards, but in the Jurassic World version, the whorl is tucked into its jaws, as a more scientifically-accurate representation of the shark.
