Arduodens

Arduodens is an extinct genus of ctenacanth fish from the Devonian period. Its name is derived from the Latin Arduus meaning steep and dens meaning tooth. It is currently known from a singular species, A. flammeus. It was described from isolated cladodont teeth found in deposits from the upper Frasnian to lower Fammenian of central Iran. The specific epithet is derived from the Latin for "flamming."^[1][2][3]
