Abstract

During micropaleontological investigations on the Lower Cretaceous successions of the Tirgan Formation in Kopet-Dagh sedimentary basin, some new achievements are yielded. in this regards, the first occurrence of Bispiraloconulus serbicus Schlagintweit, Bucur & Sudar in close association with Torremiroella hispanica Brun & Canérot is reported for the first time from the Upper Barremian of Kopet-Dagh sedimentary basin (NE Iran). The biostratigraphic investigations were carried out on a 197.5 m thick Gelian stratigraphic succession cropping out along the Tirgan Formation located 35 km southwest of Shirvan town. This study reviews the palaeogeographical distribution and age of Bispiraloconulus serbicus Schlagintweit, Bucur & Sudar and Torremiroella hispanica Brun & Canérot along the northern Tethyan margins and extends its palаeobiogeographical existence.
