A rich and diverse conodont fauna from upper Frasnian and lower-middle Famennian strata in three sections - Ghale-kalaghu, Howz-e-dorah 1 and Howz-e-dorah 2 - in the southern Shotori Range of central Iran contains forty-five taxa belonging to eight genera, dominated by icriodids and polygnathids, from the Lower rhenana Zone to the velifer Zone (= Uppermost marginifera Zone). A hiatus is documented across the Frasnian/Famennian boundary that possibly includes the Upper rhenana to the Middle triangularis Zone.
