First finds of Permian conodonts in eastern Iran and once again on the Guadalupian series base in Permian sections of the Tethyan realm

Conodonts found for the first time in eastern Iran (the Bage-Vang section) are characterized. Beds with conodonts also yield fusulinids that is suitable for refining correlation of conodont and fusulinid zonations. Stratigraphic ranges of different conodont species in the Bage-Vang section are correlated with those in the Luodian section (South China), where conodonts are also accompanied by fusulinids. As a result, some previous inferences concerning position of the Guadalupian Series base in the Tethyan sections are refined.
