Baltisphaeridium spiciferum Appendix A
From dinoflaj3
"spiciferum" (Deunff, 1955, p.146, pl.3, fig.1; text-fig.26) Downie and Sarjeant, 1965, p.96. Holotype: Deunff, 1955, pl.3, fig.1. NOW Stellechinatum (Appendix A). Originally Hystrichosphaeridium, subsequently Veryhachium (combination not validly published, Appendix A), thirdly Baltisphaeridium, fourthly Evittia Brito (combination not validly published, Appendix A), fifthly Multiplicisphaeridium (Appendix A), sixthly (and now) Stellechinatum (Appendix A). This combination was not validly published in Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym. Age: Middle Devonian.
