Sentusidinium granulosum
From Fensome et al., 2019:
Sentusidinium granulosum (Cookson and Eisenack, 1974, p.79, pl.28, fig.10) Wood et al., 2016, p.85. Holotype: Cookson and Eisenack, 1974, pl.28, fig.10. Originally Palaeostomocystis, subsequently Fromea (Appendix A), thirdly Batiacasphaera, fourthly (and now) Sentusidinium. Taxonomic junior synonym: Batiacasphaera granospina, according to Wood et al. (2016, p.85). Age: Albian–Cenomanian.

Original description as Palaeostomocystis granulosa: [Cookson and Eisenack, 1974, p.79]:
Diagnosis:
Shell elongated-oval, densely covered with minute, grana-like protuberances. Opening of shell through lifting-off of a small apical calotte.
Dimensions:
about 45 x 31 µm.
Affinities/Remarks:
The difference with respect to the similar P. scrobiculata lies in the considerably smaller size, in the slightly smaller breadth/length-ratio and in the different ornamentation. In the case of the P. granulosa one is dealing with minute tubercles, whereas the P. scrobiculata possesses small verrucae-like protuberances.
