Geological Range:
Notes: First occurrence is uncertain, but Kamptner (1955) described C. attentuatus from a sample from Rotti, Indonesia, now known to be of NN9 age (Jafar 1975), so the age is extended to NN9 here.
Last occurrence (top): Extant Data source: present in the plankton (Young et al. 2003)
First occurrence (base): within NN9 zone (9.53-10.55Ma, base in Tortonian stage). Data source: Jafar 1975
