New Records of Lower Artinskian Radiolarians and Conodonts from the Village of Donskoe (Orenburg Region, South Urals)

Forty-five radiolarian species were identified from the Upper Sakmarian and Lower Artinskian of the Shosse section, near the village of Donskoe (Orenburg Region, right bank of the Ural River). Analysis of their distribution made it possible to establish the position of the Paratriposphaera crassiclathrata–Quinqueremis arundinea Beds in the uppermost part of the section. Sample 5/44 contains the P1 element of the conodont Sweetognathus aff. asymmetricus with an unusual arrangement of pustules on the platform.
