In a section from the central Oman Mountains (Wahrah Formation, Jebel Buwaydah) well preserved radiolarians were extracted. Stratigraphically they represent typical earliest Cretaceous species (Berriasian). Besides well known Tethyan species allowing an exact age determination, unknown morphotypes are common in some samples. Some of these represent new species, which are described herein. The composition and diversity of the faunas hints to a depositionatenvironment in the lower bathyal
