Tiny Shells Reveal Planet Climate

16.03.2015

The study of foraminifera shells can tell scientists about how the climate of our planet was changing during millions of years. Foraminifera are tiny single-celled organisms that have shells. They live in the surface layer of almost all the seas and oceans, and slowly sink to the bottom after death, where their fossilized remains are found by researchers. By studying these tiny organisms, scientists can read the history of the Earth's climate changes, as a book.

Tiny Shells Reveal Planet Climate

Foraminifera shells accumulate information about environmental conditions. Currents carry them in hundreds of kilometers from the place of death. Layers of dead organisms accumulate at the bottom, and the studying their chemical composition can tell about the past very much. Now researchers are studying just these tiny shell organisms.
