Abstract
An Upper Eocene diagnostic larger foraminiferal assemblage is described and illustrated from carbonates of Deh-Rashti section, west of Rafsanjan, southeast of Iran. Thirteen taxa of benthic foraminifera were identified. This assemblage is characterized by the species Nummulites fabianii retiatus (Prever), Asterigerina rotula (Kaufmarm), Praerhapydionina cf. huberi, Fabiania sp., Pellatispira aff. Madaraszi, N. striatus, Alveolina sp., Spherogypsina sp., Gypsina marianensis, Eorupertia magna (Le Calvez), Neorotalia sp., Elphidium sp., Pyrgo sp. Based on the stratigraphic distribution of the well-known foraminifers, the Nummulites fabianii Taxon-range Zone of larger foraminifera was established. The existence of a large number of relatively elongate A-form Nummulites suggests low turbulence, oligotrophic water of middle-outer shelf palaeoenvironments of tropical to subtropical oceans.
