"mariannae" (Philippot, 1949, p.56-57; text-fig.2) Downie and Sarjeant, 1965, p.92. Holotype: Philippot, 1949, text-fig.2. NOW Achomosphaera. Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly (and now) Achomosphaera. This combination was not validly published in Downie and Sarjeant (1963, p.91), since these authors did not fully reference the basionym. Age: Late Cretaceous.
