From Fensome et al., 2019:
Pterodinium cingulatum ssp. granulatum ((Clarke and Verdier, 1967, p.45–46, pl.9, figs.5–6; text-fig.18) Lentin and Williams, 1981, p.238. Holotype: Clarke and Verdier, 1967, pl.9, fig.5; Jan du Chêne et al., 1986a, pl.88, figs.5–8. Originally Hystrichosphaera cingulata var. granulata, subsequently Spiniferites cingulatus subsp. granulatus, thirdly Spiniferites? cingulatus subsp. granulatus, fourthly (and now) Pterodinium cingulatum subsp. granulatum. Age: Cenomanian.
