Peltopleuriformes

Peltopleuriformes is an extinct order of ray-finned fish. They were a successful and morphologically diverse group throughout much of the Triassic period, with some genera in the family Thoracopteridae closely converging on modern flying fish. It was previously assumed that they went extinct during the Triassic-Jurassic extinction event, but the discovery of Peripeltopleurus jurassicus from the Early Jurassic of Italy suggests that at least one lineage survived into the Jurassic.
