Stable isotope from Miocene exceptionally preserved foraminifera from Tanzania

The dataset presents oxygen and carbon stable isotopes measured on multispecies planktonic foraminiferal shells and on Cibicidoides spp. and Uvigerina spp. (benthic foraminifera). The data were obtained from three samples from marine deposits outcropping in coastal Tanzania dating back to the early and middle Miocene. The samples are characterized by an exceptionally good preservation of foraminiferal shells.
