From dinoflaj2
"striolatum" (Deflandre, 1937b, p.72, pl.15 [al. pl.12], figs.1-2) Downie and Sarjeant, 1965, p.97. Holotype: Deflandre, 1937b, pl.15 (al. pl.12), fig.1. NOW Coronifera. Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly Exochosphaeridium, fourthly (and now) Coronifera. This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym. Age: Late Cretaceous.
