Daughter taxa (time control age-window is: 0-800Ma)
				Campylosphaera dela Narrow rimmed, arched placoliths with axial cross-bars.
				Campylosphaera differta Medium to large, elliptical to oblong Campylosphaera with a relatively narrow central area filled with broad cross-bars.
				Campylosphaera eodela Similar to C. dela but with narrow central areas largely filled by the axial cross
				Campylosphaera eroskayi Small to medium (~4-6 µm), Campylosphaera-like, broadly elliptical placolith (dark shields in XPL), with a very narrow central area filled with broad cross-bars.
				Campylosphaera sp. Specimens which cannot be assigned to any established species

Taxonomy:

Citation: Campylosphaera Kamptner, 1963

taxonomic rank: Genus

Type species: Campylosphaera bramlettei Kamptner, 1963 Junior synonym ofCampylosphaera dela (Bramlette & Sullivan, 1961) Hay & Mohler, 1967

Distinguishing features:
Parent taxon (Coccolithaceae): 2N: cells non-motile, bearing placoliths with R-unit extending from proximal shield to form upper/inner tube-cyle, mostly elliptical
N: cells motile, holococcolith-bearing
This taxon: Like Cruciplacolithus but the coccoliths are longitudinally arched and typically near parallel sided, and so appear oblong in outline

Geological Range:
Last occurrence (top): at top of NP17 zone (100% up, 37.3Ma, in Priabonian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within NP6 zone (58.97-59.54Ma, base in Selandian stage). Data source: Total of ranges of species in this database

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
Neptune data: This is a higher taxon page so Neptune data is not plotted. See also: customisable plot Parent: Coccolithaceae
