| At this rate it is possible to produce an average 100 metre thickness of coccoliths as calcareous ooze on the ocean floor in less than 200 years. |
| It consists of coccoliths, microscopically small calcite skeletons of coccolithophores, a type of algae that prospered in the Cretaceous seas. |
| Chalk, though it may include shell fragments, is predominantly composed of coccoliths from planktonic algae, forming fine-grained limestone. |
| Coccoliths are the extremely small calcareous parts of microscopic marine algae. |
| The team did not limit themselves to foraminifera but used other planktonic groups such as the coccoliths and radiolaria. |
| The living cell possesses a gelatinous sheath in which are embedded calcareous plates termed coccoliths. |
