Baltisphaeridium triplicativum Appendix A
From dinoflaj2
triplicativum (Timofeev, 1959, p.55, pl.4, fig.16) Downie and Sarjeant, 1965, p.98. Holotype: Timofeev, 1959, pl.4, fig.16. Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium. This combination was not validly published in Downie and Sarjeant (1963, p.90-91), since these authors did not fully reference the basionym. Age: Early Ordovician.
Parent: Baltisphaeridium
