Campylosphaera differta

Classification: Coccolithophores -> Coccolithales -> Coccolithaceae -> Campylosphaera -> Campylosphaera differta
Sister taxa: C. dela, C. differta, C. eodela, C. eroskayi, C. sp.,


Citation: Campylosphaera differta Bown, 2010
Rank: Species
Notes & discussion: Distinguished from other Campylosphaera species by the broad cross bars that fill the central area, and the bright inner cycle is reduced.

Distinguishing features: Medium to large, elliptical to oblong Campylosphaera with a relatively narrow central area filled with broad cross-bars.

    You list the geologic range of Camplyospheara differta as being from NP9 to NP10. However, one of the images (mine) is from NP11. Therefore, you need to adjust the geologic range of this species.

    Thanks for pointing that out - curiously though in the paper the only record is from NP10, but I guess it is a very rare species and you found it during imaging but not during the taxon count?
