Baltisphaeridium stellaeforme
Baltisphaeridium stellaeforme, (Timofeev, 1959), Downie and Sarjeant, 1965
Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium. This combination was not validly published in Downie and Sarjeant, 1963 since these authors did not fully reference the basionym.
Holotype: Timofeev, 1959, pl.4, fig.26
Age: Early Ordovician
