Magnetobiostratigraphy, lithological log, and stable isotopes curves of the Baskil section. Litho-, magneto-, and biostratigraphic data are from ref.12. Carbon (δ13C) and oxygen (δ18O) isotopes are shown for three individual genera of foraminifera, representing surface (Acarinina), thermocline (Subbotina) and bottom (Cibicidoides) conditions. Diamonds represent individual data points, whereas solid lines represent curves smoothed by 3pts moving average. The yellow shaded bar highlights the position of the MECO based on its isotopic signatures.
