Coronifera striolata ssp. striolata
From Fensome et al., 2019:
Coronifera striolata ssp. striolata Autonym. Holotype: Deflandre, 1937b, pl.15 (also labelled pl.12), fig.1.
---------------------------------------------------------------------------------------------------
Locus typicus: Paris Basin, France
Stratum typicum: 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.
