Baltisphaeridium tuberosum Appendix A
From dinoflaj2
tuberosum (Sannemann, 1955, p.345, pl.4, fig.17; text-fig.16) Downie and Sarjeant, 1965, p.98. Holotype: Sannemann, 1955, pl.4, fig.17. Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium. This combination was not validly published in Downie and Sarjeant (1963, p.91), since these authors did not fully reference the basionym. Age: Devonian (Givetian).
Parent: Baltisphaeridium
