Fadenia is an extinct genus of eugeneodontid holocephalian chondrichthyan from the Carboniferous period of Missouri (United States), the Permian period of Greenland, and the Early Triassic epoch of British Columbia, Canada (Sulphur Mountain Formation).[1][2]
Classification
[change | change source]Fadenia is a member of the Eugeneodontiformes, an extinct order of chondrichthyans. They are known for having tooth whorls. The order includes popular fishes such as Helicoprion, Ornithoprion, Edestus, and Caseodus. It is one of the few eugeneodonts that survived the Permian–Triassic extinction event and is one of the last surviving genera in this order. The fish could reach about 1.5 metres (4.9 ft) in length.[1][3]
