The Enchodontoidei are an extinctsuperorder of aulopiform fish known from the Early Cretaceous to the Eocene.[1] They were among the dominant predatory marine fish groups in the Late Cretaceous, achieving a worldwide distribution. They were an extremely diverse group, with some developing fusiform body plans whereas others evolved elongated body plans with long beaks, superficially similar to eels and needlefish.[2] They could also grow to very large sizes, as seen with Cimolichthys and Stratodus, the latter of which is the largest aulopiform known. Their most famous member is the widespread, abundant, and long-lasting genus Enchodus.
Most enchodontoids went extinct at the end of the Cretaceous, although some dercetids survived into the Early Paleocene and Stratodus into the Early Eocene of the Trans-Saharan seaway.[3][4] Some remains of Enchodus have also been recovered from the Paleocene and Eocene, although this may just represent reworked material.[5][6][7]
