"spinosum" (White, 1842, p.37, pl.4, fig.6) Downie and Sarjeant, 1965, p.96. Holotype: White, 1842, pl.4, fig.6. NOW Exochosphaeridium?. Originally Xanthidium (Appendix A), subsequently Hystrichosphaeridium, thirdly Baltisphaeridium, fourthly Cordosphaeridium (combination not validly published), fifthly Exochosphaeridium, sixthly (and now) Exochosphaeridium?. Junior homonym: Baltisphaeridium spinosum Rasul, 1979, an acritarch species. This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym. Age: Late Cretaceous.
Parent: Baltisphaeridium
