Megactenopetalus is an extinct genus of petalodont fish which lived from the late Early Permian through the Late Permian.[1] It is known from a single species: M. kaibabanus. It was one of the last and largest petalodonts; estimates place it at 1.6 meters or 5.2 feet in length with a 20 centimeter or 7 inch mouth. It is known from the southwest of the United States , the Middle East, and China . The holotype was an upper left dentary which came from the Kaibab Formation on the northern rim of the Grand Canyon.[2] It is probably closely related to Ctenoptychius.[3]
