In this study the biostratigraphy of Upper Cretaceous deposits (Gurpi Formation) in
Sepidan section located in the Interior Fars basin (SW Iran) was studied. The Gurpi
Formation in Sepidan section consists of 360 m lime shale, argillaceous limestone and
shale laid continuously on Ilam Formation and with a paraconformity under Pabdeh
Formation. 9 genera and 27 species of planktonic foraminifera have been identified in
the Sepidan section. On this basis, the Gurpi Formation in the Sepidan section
includes 9 biozones in the Santonian age at the end of Maastrichtian. Biostratigraphy
studies indicate that the biozones identified in this section resemble considerably
other biozones of the world standard presented for Upper Cretaceous
