Scanning electron micrograph (SEM) of a fossil of the skeleton (coccosphere) of a coccolithotrope (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 limestone rocks that was laid down in the Cretaceous period, between 142 and 65 million years ago. Magnification is 5000x at 12.7cm image size. | |
