Calcareous phytoplankton fossil. Coloured scanning electron micrograph (SEM) of a fossil coccolith from the skeleton (coccosphere) of the coccolithophore Calcidiscus leptoporus,a small marine algal organism. The coccosphere consists of plates (coccoliths) of calcium carbonate. These skeletons can make up the major component of a limestone rock laid down in the Cretaceous period,between 142 and 65 million years ago.
