A small collection of ammonites from the Middle to Upper Jurassic (Bathonian to Oxfordian) Dalichai Formation of the eastern Binalud Mountains (southern Koppeh Dagh, northeastern Iran) yielded several taxa that were previously unknown from Iran, i.e. Lingulaticeras nudatum (Oppel),
Hecticoceras (Rossiensiceras) aff. metomphalum Bonarelli, Horioceras sp., Collotia sp., ?Homoeoplanulites sp. (with in situ aptychus), and Euaspidoceras aff. douvillei (Collot). These records are described and figured herein and significantly
extend our knowledge of the geographical distribution of these taxa. Palaeobiogeographically, the described taxa are related to the Submediterranean Province.
