Visbysphaera gotlandica Appendix A

gotlandica (Eisenack, 1954a, p.209, pl.1, fig.5; text-fig.6) Kiryanov, 1978, p.87–88.  Holotype: Eisenack, 1954a, pl.1, fig.5.  Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Multiplicisphaeridium (Appendix A), fourthly (and now) Visbysphaera.  Taxonomic junior synonym: Baltisphaeridium peltatum Cramer, 1966, an acritarch species, according to Cramer (1970, p.157).  This combination was not validly published in Lister (1970, p.98) since that author did not clearly use the name Visbysphaera gotlandica.  Age: Silurian (late Llandovery).
