Permian

HOW BIG IT WAS

Helicoprion relative size depiction as described below
Helicoprion was approximately 3 m long.

Although the fossil of Helicoprion looks like a shell, this spiral-shaped structure is a ‘whorl’ of teeth from a shark unlike any shark alive today. This tooth whorl formed part of the lower jaw and probably helped grasp prey. Helicoprion grew to nearly three metres. This type of shark survived the Permian extinction.
