    Scarce data on the occurence of anaptychi and aptychi in shells of Lower Cretaceous ammonites were summarized and compared with the current classification of ammonites. It is suggested that the Haploceratoidea did not survive the Hauterivian and supported the view that the Desmoceratoidea originated from the Phylloceratina.
