Ctenacanthoidea is an extinct superfamily of prehistoric Elasmobranchs. These nectonic carnivores first appeared around 407 million years ago, during the Devonian, and survived until the early Cretaceous.[2] A Miocene record, Wodnika ocoyae, is now considered a concretion.[3] Fossils belonging to this group have been found worldwide.[4]
