The first finds of Upper Devonian radiolarians in cherty rocks of the Akbasay Formation, Zeravshan-Gissar mountainous area, are reported. Nineteen species of spherical and spiny forms were identified and assigned to 8 genera. Finds of co-occurring conodonts and radiolarians enabled the refinement of the proposed age of radiolarian associations.
