Baltisphaeridium dignum Appendix A
From dinoflaj2
dignum (Sannemann, 1955, p.327, pl.1, fig.5; pl.4, fig.11; text-fig.7) Downie and Sarjeant, 1965, p.89. Holotype: Sannemann, 1955, pl.4, fig.11. Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium. This combination was not validly published in Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym. Age: Devonian (Late Givetian).
Parent: Baltisphaeridium
