Scombriformes

Scombriformes is an order of bony fish containing nine families which were classified under the suborders Scombroidei and Stromateoidei, of the wider grouping known as Perciformes, Fishes of the World, 5th ed. (2016), recognised the order but subsequent workers have suggested that Scombriformes forms part of the larger Pelagiaria clade.

The earliest scombriform is Landanichthys from the Middle Paleocene of Angola.
