Abstract
In this research, benthic foraminifera from the Upper Cretaceous Maastrichtian in the Tutak section (Eastern Iran) was studied for the first time. In the Tutak section, there are outcrops of scattered and lenticular Maastrichtian carbonate sediments between the ophiolitic units. Some of the benthic foraminifera identified in this section are Orbitoides apiculatus, Orbitoides medius, Omphalocyclus cf. macroporus, Orbitoides cf. gruenbachensis, Orbitoides gensacicus, Orbitoides spp., Sirelina orduensis, Canalispina iapygia, Goupillaudina spp., Selimina spinalis, Postomphalocyclus merici. Since there is no comprehensive study of this benthic foraminifera in eastern Iran, the authors suggest the name of the Makhunik unit for these Maastrichtian sediments in the Flysch Basin in the eastern part of Iran.
