When the oceans warm up, there is a decrease in the ratio of the isotope oxygen-18 to ordinary oxygen in the shells of the little creatures; when temperatures go down, the concentration of oxygen-18 goes up. Moreover, the proportions are preserved after the creatures die and sink to become layers of sediment. Thus, because these layers can now easily be dated, the shells...
