Ceratodus, a genus of Dipnoi, with two species, from the fresh waters of Queensland. The name was originally given to a genus of fish founded on fossil teeth, of Triassic and Jurassic age from Europe, India, and America - their chief British locality being Aust, near Bristol. The living genus, discovered in 1870, received the same name owing to similarity of dentition.
