Ceratodus (from Greek: κέρας kéras, 'horn' and Greek: ὀδούς odoús 'tooth') is an extinct genus of lungfish. It has been described as a "catch all", and a "form genus" used to refer to the remains (typically toothplates) of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become extinct sometime around the beginning of the Eocene Epoch.
