Kallosphaeridium ringnesiorum
From dinoflaj2
?ringnesiorum (Manum and Cookson, 1964, p.15, pl.2, fig.10) Helby, 1987, p.324-325. Holotype: Manum and Cookson, 1964, pl.2, fig.10. Originally Canningia, subsequently Canningia?, thirdly Batiacasphaera, fourthly Chytroeisphaeridia, fifthly (and now) Kallosphaeridium?. Questionable assignment: Helby (1987, p.324-325). The epithet is correctly rendered as "ringnesiorum", rather than "ringnesii", since the species is named for the Ringnes brothers. Tocher and Jarvis (1987, p.151) also proposed this combination, but without question. Age: Campanian-Maastrichtian.
Parent: Kallosphaeridium
