Amelacanthus is an extinct genus of elasmobranchian cartilaginous fish from the Paleozoic era.[1][2] It is known from fin spines and currently contains four described species. It is known from the Permian and Carboniferous of North America, Europe, and Africa.[3][2] It is also known from the Famennian of Russia.[4] Possible specimens of Amelacanthus were found in Permian (Wordian) sediments of Oman.[5]
