Stratodus ("layer tooth") is a genus of giant prehistoric aulopiform fish found in Cretaceous-aged marine strata of Kansas, Alabama, Morocco, Israel, Niger, South Dakota, and Jordan. It has also been found in the Tamaguélelt Formation of Mali, dating to the Lower Eocene, indicating that Stratodus survived the Cretaceous-Paleogene extinction event. This sleek fish has an upper jaw filled with multiple rows of tiny teeth and was the largest aulopiform, reaching in length.

== History of discovery == Stratodus was initially described by Edward Drinker Cope in Kansas during 1872, naming the type species S. apicalis, and described a second species in 1877, S. oxypogon, both species being assigned to the family Stratodontidae. S. oxypogon is now often considered a synonym of S. apicalis, and the family was shifted from Stratodontidae to Dercetidae, some has gone back to Stratodontidae while others support attribution to Dercetidae.
