Tropical Indian Ocean planktonic and benthic foraminifera have 13C/12C ratios which change abruptly within Magnetic Epoch 6 about 6.2 million years ago. All species analyzed in the Late Miocene section of DSDP Site 238 show a shift towards lighter values of delta13C by about 0.8‰. The oxygen isotope...
