Australosomus is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch.[1]

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.[2]

Australosomus is one of many genera to arise after the Permian extinction, only to die out during the Triassic extinction.[2]
