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 genera Miscellanea , Operculina , Lockhartia , Rotalia , Akbarina , Pseudocuvillerina , Smoutina , Davisina , Idalina , Valvulina , Laffitteina , and Ranikothalia are 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 paper Ranikothalia sindensis partial zone was reported in association with Miscellanea miscella , M. juliettae and M. yvettae .
