See text Edaphodon was a fish genus of the family Callorhinchidae (sometimes assigned to Edaphodontidae).

As a member of the Chimaeriformes, Edaphodon was a type of rabbitfish, a cartilaginous fish related to sharks and rays.

[4] Edaphodon would have used its tritors for both crushing hard-shelled and slicing other prey such as fishes, sharks, and marine reptiles.

[5] In the Upper Cretaceous of Alabama, where I. bifurcatus, E. barberi, and E. mirificus coexisted, the two genera may have had different diets, with Ischyodus feeding on more hard-shelled prey.

[2] According to living callorhynchid and rhinochimaerid specimens, palatine plate represents 4 percent of the length between gill opening and body tip excluding elongated tail.
