The foraminifers from the Lower Carnian (Upper Triassic) deposits on the Laptev Sea coast (the north of Central Siberia) were studied. Three new species of the spiral nodosariids (Dainitella insueta sp. nov., Marginulinopsis incompta sp. nov., and Astacolus dolganensis sp. nov.), widespread in the Osipa Formation and the lower parts of the Nemtsova and Chaidakh formations on the Laptev Sea coast, are described.
