The authors of its description considered it to be an exclusively Cretaceous genus, containing species living from Hauterivian to Cenomanian.<ref name=Underwoodetal11 /> Subsequently the species ''G. dentatus'' was described from the Valanginian of France.<ref name=CRValanginianelasmobranch /> Teeth described by Adolfssen and Ward (2015), collected from the middle Danian Faxe Formation at Faxe, Denmark, extend the temporal range of the genus to Paleocene; according to the authors, the species ''"Notorynchus" serratissimus'' Agassiz (1843) should probably be assigned to the genus ''Gladioserratus'' as well, which, if confirmed, would further extended the temporal range of the genus to the early Eocene.<ref name=appAdolfssenWard>{{cite journal |author1=Jan S.
