Troglocladodus (meaning "cave Cladodus" or "cave branching-tooth") is an extinct genus of cartilaginous fish in the family Ctenacanthidae. Remains are known from Mammoth Cave, Kentucky, in limestone deposits dated to the Mississippian subperiod of the Carboniferous period. A single species has been identified, Troglocladodus trimblei, which is based on isolated teeth.[1][2]
