Edestus heinrichi was a large shark-like fish that lived in the shallow seas on the Pennsylvanian. They were formidable predators, growing up to 22 feet and had mouth full of bizarrely positioned teeth. The Edestus did not simply shed its teeth like more modern sharks, it instead had a ‘tooth whorl’ which acted a bit like a conveyer belt of teeth–– the old teeth would migrate forward to make room for new ones. Near the front of its mouth, its jaws curled outward, resulting in a strange but effective tool for catching prey.
