Helicoprion Helicoprion, meaning ("Spiral Saw"), is an extinct genus of whorl-toothed shark that first arose in the oceans of the Late Carboniferous, approximately million years ago, and survived the Permian-Triassic extinction event, and eventually went extinct during the Early Triassic, some million years ago. Its fossils can be found in Russia and in the Western U.S. but no other Class: Chondrichthyes.
