A Late Permian (Severodvinian stage) outcrop with numerous fossils is located on the floodplain of the left bank of the Sukhona river, in front of eastern part of Poldarsa. Numerous ostracod and bivalve shells, bones and coprolites of fishes and chroniosuchid Suchonica vladimiri were collected from these deposits. Due to the presence of chroniosuchids, this locality was assigned to Kotelnichsky subcomplex.[5]
