Enchodus
''Enchodus'' is an extinct genus of bony fish. It flourished during the Upper Cretaceous. ''Enchodus'' survived the Cretaceous–Paleogene extinction event and persisted at least into the Eocene.
==Description==
''Enchodus'' species were small to medium in size. One of the genus' most notable attributes are the large "fangs" at the front of the upper and lower jaws and on the palatine bones, leading to its misleading nickname among fossil hunters and paleoichthyologists, "the saber-toothed herring". These fangs, along with a long sleek body and large eyes, suggest ''Enchodus'' was a predatory species.
The largest-known species of ''Enchodus'' is ''E. petrosus'', remains of which are common from the Niobrara Chalk, the Mooreville Chalk Formation, the Pierre Shale, and other geological formations deposited within the Western Interior Seaway and the Mississippi Embayment. Large individuals of this species had fangs measuring over in length, though the total body length was only about , giving its skull an appearance somewhat reminiscent of modern deep-sea fishes, such as anglerfish and viperfish. Other species were smaller, some like ''E. parvus'' were only some cm (a few inches) long.
Despite being a formidable predator, remains of ''Enchodus'' are commonly found among the stomach contents of larger predators, including sharks, other bony fish, mosasaurs, plesiosaurs and seabirds such as ''Baptornis advenus''.
