- Diagnosis
- Coccospheres of Centumgemina are spherical and vary in diameter from 11 um to 19um. They are formed by a large number (from about 140 to about 250) of very tiny placoliths whose long axis is <4um. Both shields are elliptical, monocyclic and of extreme simplicity. Each shield consists of more than twenty flat rhombohedric elements which are broader at the poles. No elaborated structure fills the central area which is reduced to a central depression aligned with the longer axis of the placolith.
