Ventimolina stellata


Classification: ntax_cenozoic -> Coccolith families inc sed -> Papposphaeraceae -> Ventimolina -> Ventimolina stellata
Sister taxa: V. stellata

Taxonomy:

Citation: Ventimolina stellata Thomsen, Ostergaard & Cros 2015
Rank: Species
Synonyms: Unidentified sp. 2 in Cros and Fortuño 2002 - Fig. 111D

Farinacci & Howe catalog pages: V. stellata *


Morphology: Coccosphere ca 10 x 5 µm with ca 12 CFCs 
BCs - oval ca 1.0 x 0.4 µm; rim narrow with slightly vaulted axial cross; low central spine supports flat cross-shaped calyx. Rim formed of single cycle of rod-shaped elements.
CFCs - base similar to BCs, spine elevated and with axe-like blade aligned paraell to short axis of coccolith.


Ecology & Biogeography: Low latitude species, probably mid/lower-photic, rare. Recorded from NW Mediterranean and E. Indian Ocean

Biology & life-cycles: Holococcolith phase not identified

Phylogenetic relations: The base is rather similar to that of Wigwamma whilst the process is more like those of Pappomonas supporting the broader concept of the Papposphaeraceae.
