''Coccodontidae'' is an extinct family of extinct pycnodontid fish that lived during the lower Cenomanian. The various genera had massive, curved spines. The family is composed of two genera, the type genus ''Coccodus'', and ''Hensodon''. Originally, the family also contained the genera ''Trewavasia'' and ''Ichthyoceros'', with ''Trewavasia'' thought to be the sister genus of ''Hensodon''. Later, ''Trewavasia'' and ''Ichthyoceros'' were moved to a separate, but closely related family, "Trewavasiidae." ==See also==
