Mawsonia is an extinct genus of prehistoric coelacanth fish. It is amongst the largest of all coelacanths, with one quadrate specimen (DGM 1.048-P) possibly belonging to an individual measuring 5.3 metres (17.4 feet) in length. It lived in freshwater and brackish environments from the late Jurassic to the mid-Cretaceous (Kimmeridgian to Cenomanian stages, about 152 to 96 million years ago) of South America, eastern North America, and Africa.
