Cardabiodontidae is an extinct family of lamniform sharks. Confirmed members of this family include Cardabiodon and Dwardius , both which are genera which existed in Australia, North America, and Europe during the Late Cretaceous period.^[1]^[2] It has been suggested that Parotodus could also belong to this family, but the authors that originally made this proposal expressed a weakening of rationale for it.^[3]
