Coronifera striolata
From Fensome et al., 2019:
Coronifera striolata (Deflandre, 1937b, p.72–73, pl.15 [also labelled pl.12], figs.1–2) Stover and Evitt, 1978, p.148. Holotype: Deflandre, 1937b, pl.15 (also labelled pl.12), fig.1. Originally Hystrichosphaeridium, subsequently
Baltisphaeridium (Appendix A), thirdly Exochosphaeridium, fourthly (and now) Coronifera. See also the
discussion under Operculodinium hirsutum. Age: Late Cretaceous.
---------------------------------------------------------------------------------------------------
Supplemental diagnosis: Davey, 1969, p. 164: Exochosphaeridium striolatum
Shell subspherical to ovoidal. Processes numerous, variable, fibrous, often bifurcate medially and sometimes terminating witll small fork. Proccsses distally may be pointed or blunted. Fibres pass down length of processes onto shell surface and there join with similar fibres from adjacent processes. Apical process and precingular archaeopyle may be present.
