Coriops

Coriops is a genus of prehistoric fish. Its fossils are found in Campanian (Mesa Verde Formation), Maastrichtian (Hell Creek Formation), and possibly Paleocene (also Hell Creek) age deposits. This chronological distribution means that the genus may have survived the Cretaceous–Paleogene extinction event that killed the dinosaurs.

Classification

Sepkoski's compendium of marine fossil genera has it classified as an eel, but it has been classified in the Elopiformes and the Osteoglossomorpha.
