The Makran coastal strip in southeastern Iran consists of marl, sandstone, and Pleistocene-age siliceous-carbonate detrital units deposited in an energetic environment under the influence of waves. Marl units with a thickness of nearly 8 meters have the highest outcrop in the area and have countless fossils of different species of deep and benthic basin. In field studies, whale fossil remains were identified in these sediments. In order to determine the age of this fossil, these fossil remains have been identified and accompanying fossils in marl deposits have been used. Based on this, 12 genera and 13 species of deep and benthic foraminifera with hyaline and porcelain wall were identified by performing thin section microscopic studies and using SEM electron microscopy. The paleontological results of the whale fossil and also based on the most characteristic fossils associated with it such as Textularia, Globigerina, Globorotalia, Nummulite, and Microgastropoda show the Middle to Late Miocene age in this region.
