Stomiosphaera radiata
From dinoflaj3
radiata (Vogler, 1941, p.281, pl.20, fig.1) Dufour, 1968, p.1948. Holotype: Vogler, 1941, pl.20, fig.1. Originally Cadosina, subsequently (and now) Stomiosphaera. Dufour did not reference the basionym when proposing this combination, but this was not a requirement since he was using zoological nomenclature. Age: Neocomian? (Kimmeridgian according to I. Nagy, 1966, p.88).
Parent: Stomiosphaera
