Batiacasphaera bellula
From dinoflaj2
?bellula (Jiabo, 1978, p.51, pl.23, figs.14-16) Jan du Chêne et al., 1985a, p.15. Holotype: Jiabo, 1978, pl.23, fig.15. Originally Tenua Eisenack, subsequently Kallosphaeridium?, thirdly Batiacasphaera, fourthly (and now) Batiacasphaera?, fifthly Sentusidinium. Questionable assignment: Marheinecke (1992, p.76). In transferring this species to Sentusidinium, Xu Jinli et al. (1997, p.46) did not discuss the full history of this taxon; we therefore prefer to retain it questionably in Batiacasphaera. Age: Early Tertiary.
Parent: Batiacasphaera
