Aetheolepis
Aetheolepis mirabilis is an extinct species of prehistoric archaeomaenid ray-finned fish that lived in freshwater environments in what is now Western Australia and New South Wales. A. mirabilis is easily distinguished from other archaeomaenids by having a deep, discoid-shaped body. Fossils of A. mirabilis have been found in the Talbragar River fossil beds of New South Wales and the Colalura Sandstone of Western Australia.
