Cleistosphaeridium leve
From dinoflaj3
"leve" (Maier, 1959, p.308, pl.30, figs.1–2) Davey et al., 1969, p.16. Holotype: Maier, 1959, pl.30, fig.1; Sarjeant, 1983, pl.2, fig.3, pl.5, fig.1; text-fig.2. Originally Galea (generic name illegitimate), subsequently Baltisphaeridium (Appendix A), thirdly Cleistosphaeridium. Taxonomic senior synonym: Galea (now Chiropteridium) galea, according to Sarjeant (1983, p.108–109). This combination was not validly published in Davey et al. (1966, p.170), since these authors did not fully reference the basionym. Age: late Oligocene–middle Miocene.
Parent: Cleistosphaeridium
