One of a kind of minute, calcareous bodies, probably vegetable, often abundant in deep-sea mud.
a single disc-like plate which is secreted by the algal organism and held in combination with several other, sometimes varying shaped plates by an organic coating to form the coccosphere
The calcite plate of a coccolithophore that makes up the Chalk of the hills
Coccolith - A general term applied to various microscopic calcium-rich structures or button-like plates having various shapes and averaging about 3 microns in diameter, constituting the outer skeletal remains of a coccolithophore. Coccoliths are found in chalk and in deep-sea oozes of the temperate and tropical oceans and were probably not common before the Jurassic.
A small round body, found in chalk formations.
calcareous structure formed by coccolithophore. {Huxley 1868
Coccoliths are individual plates of calcium carbonate formed by coccolithophores (single-celled algae such as Emiliania huxleyi) which are arranged around them in a coccosphere.
