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 & canerot 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 & canerot along the northern tethyan margins and extends its pal?eobiogeographical existence.

An Upper Jurassic-Lower Cretaceous carbonate platform from the Vâlcan Mountains (Southern Carpathians, Romania): paleoenvironmental interpretationThe results of a biostratigraphic and sedimentological study of the Upper Jurassic-Lower Cretaceous limestones cropping out in the southern sector of the Vâlcan Mountains in Romania are presented, including the definition of microfacies types, fossil assemblages and environmental interpretation. Six microfacies types (MFT 1-MFT 6) have been identified, each of them pointing to a specific depositional environment. The deposits are characteristic of a shallow carbonate platform. They contain normal marine or restricted marine facies deposited in low or high energy environments from the inner, middle and outer platform. The age attribution of these deposits (Late Jurassic to Berriasian-Valanginian-?Hauterivian, and Barremian) is based on foraminiferal and calcareous algae associations. The micropaleontological assemblage is exceptionally rich in the Vâlcan Mountains and brings new arguments for dating the Upper Jurassic-Lower Cretaceous limestones in this area.

Two echinoid species from the Sarcheshmeh Formation, early Aptian, Lower Cretaceous, of the Kopet-Dagh Basin, NE Iran, are described: a phymosomatoid specimen of Tetragramma sp., and the spatangoid echinoid Miotoxaster collegnii (Sismonda, 1844). This is the first report of echinoids from the Sarcheshmeh Formation from northeastern Iran.
