Abstract
The middle portion of Member A of Geirud Formation has yielded three goniatites, which could be related to the genera Sporadoceras and Platyclymenia respectively. These genera confirm a Famennian age for the above-mentioned member. With regards to the previous discovery of these genera of goniatites in east Iran, it may be concluded that a similar paleoecological condition and marine communication existed both in east, as well as north Iran during this period of time.
