Delphyodontos dacriformes is a prehistoric basal cartilaginous fish from the Late Mississippian-aged Bear Gulch Limestone Lagerstätte of Montana. The adult form is unknown, as the only fossil specimens are of aborted fetuses or recently born young. Sharp teeth and fecal matter in the fossils suggests that Delphyodontos practiced intrauterine cannibalism.
