Baltisphaeridium franconium Appendix A
From dinoflaj2
franconium (Sannemann, 1955, p.328, pl.3, fig.1; pl.5, figs.1-2) Downie and Sarjeant, 1965, p.90. Holotype: Sannemann, 1955, pl.5, fig.1. 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
