Corisphaera sp. type B


Classification: ntax_cenozoic -> Holococcoliths -> bridged -> Corisphaera -> Corisphaera sp. type B
Sister taxa: C. gracilis, C. sp. type B, C. tyrrheniensis, C. sp.

Taxonomy:

Citation: Corisphaera sp. type B Kleijne, 1991
Rank: type

Distinguishing features: Similar to H. cornifera but BCs more delicate and symmetrical, CFCs with less well developed leaf. (zygoliths rather than helladoliths).

Farinacci & Howe catalog pages:


Biology & life-cycles: Cros et al. (2000) documented a possible association with Syracosphaera delicata, but this association is still unproven.
