Orthacanthus is a genus of prehistoric freshwater shark that lived during the Paleozoic era (400-225 mya). It was a member of a group of ancient sharks called xenacanths, all of which were freshwater sharks with long fins down their backs and a spine at the start of the fin. It was the largest of the known xenacanths.
