Oxygen Isotopic Composition of Some Right-and Left-Coiled Foraminifera.
Right-and left-coiled foraminiferal species were collected from living and fossil faunas from different habitats. A difference in the oxygen isotopic composition of right-and left-coiled specimens was observed. Deposition of calcium carbonate by right-and left-coiled Foraminifera takes place, at least in the species measured, during non-coincident periods of the year.
