Ceratodus (fromAncient Greek:κέρας,romanized: kéras,lit.'horn' andὀδούς,odoús,'tooth')[2] is an extinct genus of freshwaterlungfish that was found worldwide during theMesozoic Era. It has been described as a "catch all",[3] and a "form genus"[4] used to refer to the remains (typically toothplates) of a variety of lungfish belonging to the extinct familyCeratodontidae. Fossil evidence dates back to theEarly Triassic.[5] A wide range of fossil species from different time periods have been found around the world in places such as theUnited States,Argentina,Greenland,England,Germany,Egypt,Madagascar,China, andAustralia.[6]Ceratodus is believed to have become extinct sometime around the beginning of theEocene Epoch.
