A detailed study has been made of the uppermost Maastrichtian–lower Danian marls of the Gurpi Formation, which are exposed at the Izeh section (central part of the Zagros Basin, southwestern Iran), and which were deposited above the compensation depth. The study has yielded diverse and abundant planktonic foraminifera, whose distribution allows the Cretaceous–Palaeogene boundary to be placed at about 1.5 m from the base of the studied series. Within this series, all the characteristic planktonic foraminiferal biozones are recorded. In addition, the results allow a model of extinction and turnover to be established.
