The interlocking scales (3 to 4 times long as wide), deeply forked caudal fin all help to distinguish this genus, which is known from Triassic rocks in Greenland, Africa, Madagascar, British Columbia and Vancouver.[3]
Australosomus is one of many genera to arise after the Permian extinction, only to die out during the Triassic extinction.[3]
