Protoellipsodinium clavulus ssp. spinigerum
From Fensome et al., 2019:
Protoellipsodinium clavulus ssp. spinigerum (Brideaux, 1977, p.30, pl.12, figs.8–9; pl.13, figs.1–11) Duxbury, 2019, p.200. Holotype: Brideaux, 1977, pl.12, figs.8–9; pl.13, figs.1–4. Originally Operculodinium? spinigerum, subsequently Protoellipsodinium spinigerum, thirdly (and now) Protoellipsidinium clavulus subsp. spinigerum. Taxonomic senior synonym: Protoellipsodinium clavulum, according to Duxbury (1983, p.53) — although this synonymy is still technically correct, we usually indicate such synonymies only when infraspecific taxa have been completely subsumed under the senior species name and not retained as separate (albeit included) entities. Age: Barremian.
