Thoracopteridae

Thoracopteridae is an extinct family of prehistoric bony fish classified with the order Peltopleuriformes, containing four genera: Thoracopterus, Gigantopterus, Potanichthys and Italopterus. This lineage of Triassic flying fish-like Perleidiformes converted their pectoral and pelvic fins into broad wings very similar to those of their modern counterparts. However, this group is not related to modern flying fish from the family Exocoetidae, instead being a case of convergent evolution.
