Which will be the difference with Coccolithus staurion?

Jeremy Young (UCL, UK)
This is not a very well worked out taxon but C. staurion has a more robust cross that nearly fills the c area and is clearly visible in LM. By contrast in C. tenuiforatus the cross is delicate and not really visible in LM.
