Istiophoriformes are an order of bony fish which is not fully recognized by some taxonomists, with some including the two extant families Xiphiidae and Istiophoridae,[1] and others, including the family Sphyraenidae.[2]

The earliest fossils of this group are of early billfish from the Late Paleocene of Peru and Turkmenistan.[3][4]
