Thu, 11/10/2007 - 15:20 — Jeremy Young

Calcidiscus macintyrei (Bukry and Bramlette, 1969) Loeblich and Tappan, 1978 [Cyclococcolithus]

Description: Large circular species of Calcidiscus with central opening.

Remarks: Usually confined to specimens >10μm to allow unambguous biostratigraphic use. Essentially this is a large variant of C. tropicus.

Range: NN17 to 19 (use of the name C. macintyrei is normally confined to the large specimens occurring in this time interval although similar morphotypes do occur in the Miocene).
