Taxonomy:

Citation: Ceratolithus cristatus Kamptner 1950 HET nishidae type sensu Young et al., 2003
Rank: informal
Basionym: Neosphaera coccolithomorpha var. nishidae Kleijne 1993
Synonyms: Craspedolithus vidalii Bukry 1975 [since the name nishidae is being used informally seniority probably does not need to be followed, but Kleijne 1993 included in her synonymy the images from McIntyre & Be 1967 used by Bukry 1975 as his holotypes ]

Distinguishing features: Ceratolithus heterococcoliths with narrow central opening

Farinacci & Howe catalog pages: Neosphaera coccolithomorpha nishidae [no catalog entry yet], Craspedolithus vidalii *


Size: opening diameter 0.15-0.3x coccolith diameter, lith diameter 4-7 microns - Kleijne (1993)
