       Ornithoprion was a carboniferous shark that was also related to the sharks Edestus, perhaps better known as the Scissor toothed shark, and Helicoprion. In fact it was the discovery of Ornithoprion that allowed for a more accurate reconstruction of Helicoprion with how the distinctive tooth-whorl fitted inside the mouth.
