ABSTRACT: This study is the
micropaleontological investigation of the Chehel-Kaman Formation of Paleocene
age from Kopet-Dagh basin, NE of Iran. Thirty three species of diagnostic
benthic foraminifers belonging to generaMiscellanea,Operculina,Lockhartia,Rotalia,Akbarina,Pseudocuvillerina,Smoutina,Davisina,Idalina,Valvulina,Laffitteina,andRanikothaliaare recorded based on detailed
petrographic analysis. The rocks are entirely shallow marine in rigin with
biotic assemblages confirming Chehel-Kaman Limestone of the Paleocene age. The
analyses of benthic foraminifers suggest that the deposition of the Paleogene
sequence occurs in warm and shallow marine environments. In this paperRanikothalia sindensispartial zone was reported in
association withMiscellanea miscella,M.
juliettaeandM. yvettae.
