Calcidiscus quadriperforatus HOL
Cenozoic Taxa
Calcidiscus quadriperforatus HOL
Edited by Jeremy Young on Thu, 22/04/2010 - 09:28Calcidiscus quadriperforatus (Kamptner 1937) Quinn & Geisen in Saez et al. 2003 HOL [Syracosphaera]
Description: Coccolith structure - coccoliths are open tubes with internal septae (walls). The outer tube wall shows hexagonal fabric and the crystallites have radial c-axes (birefringent in plan view in LM). The fabric of the septae is not obviously different but they are non-birefringent in plan view in LM and so the calcite crystallites must have vertical c-axes.
Coccospheres monomorphic, nearly spherical.
Coccolith form - the internal septae define 4-6 pores, tube 10-15 crystallites high, castellated, higher where it meets internal walls. Base open.
Remarks:
Original description:
Size: Liths 2-3 µm long.
Life-cycle: The association of this holococcolith with the large Calcidiscus leptoporus (sensu lato) morphotype is still based on a single specimen, but it is an exceptionally clear combination coccosphere (Geisen et al. 2002).
