Ontogenetic isotopic variation in foraminifera – Implications for palaeo proxy

The oxygen isotopic composition (δ18O) of Marginopora kudakajimaensis (Foraminiferida) is found to differ by 0.5‰ among the individuals living under similar physico-chemical conditions. The δ18O variation along the growth direction (ontogeny) is much higher, ranging between 1.5 and 2.5‰. In comparis...
