Taxonomy:

Citation: Syracolithus sp. type A Kleijne, 1991

Rank: type

Distinguishing features: Coccoliths with area inside tube almost filled by concentric walls, distal surface ornamented by 10-15 pyramidal bosses.

Farinacci & Howe catalog pages:

Phylogenetic relations: The affinities of this species are not sure, and it has not been observed by light microscopy. The structure looks similar to Zygosphaera, especially Z. marsilii, but it is monomorphic whilst Zygosphaera species all have well-differentiated CFCs, and there is no central ridge. So rather tentatively, it is left here.

Geological Range:
Last occurrence (top): Extant Data source: present in the plankton (Young et al. 2003)
First occurrence (base): within No known fossil record modern (0.00-0.00Ma, base in "Holocene" stage). Data source: [JRY rough estimate]

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
(NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: septate
