Calcidiscus quadriperforatus
Cenozoic Taxa
Calcidiscus quadriperforatus
Edited by Jeremy Young on Sun, 10/04/2011 - 11:33Calcidiscus quadriperforatus (Kamptner 1937) Quinn et al. 2004 [Syracolithus]
Description: Coccoliths large sized, 7-11 µm, with 20-35 elements; distal shield sutures smoothly curved on shield then obscured around crest of tube.
Remarks: Separation of this morphotype from the rest of modern Calcidiscus was initially suggested by Kleijne (1993) on morphological grounds and has been strongly supported by culture observations, life-cycle studies (it produces distinctive holococcoliths) and molecular genetics.
