Black (1967) reported the diameter of the basal placolith in the holotype as 4.6 μm.
Circular basal placoliths with a diameter of less than 5.0 μm are assigned to Prediscosphaera cantabrigensis. Based on many years of tracking its stratigraphic range, the highest occurrence of this species is considered to be in the Late Coniacian.
