A Cenomanian radiolarian assemblage has been extracted from undifferentiated Cretaceous pelagic strata from northeast of Zagros fold-thrust belt. These strata are remnants of deep marine sediments including the radiolarian ooze topping the oceanic crust of Neo-Tethys. Extracted Radiolaria assemblage is characterized by Thanarla veneta (Squinabol), Holocryptocanium sp. H. astiensis Pessagno, Pseudodictyomitra sp. A. Pessagno. This assemblage is assignable to Cenomanian. Presence of this assemblage indicates the Neo-Tethyan realm was in an oceanic stage in Cenomanian.
