Microfauna assemblages dating the uppermost Kyra and the lowermost Kelimyar Formations (Kurung Mbr) are defined for the first time in the reference Jurassic sections situated in the northeastern Siberian Platform (Kelimyar River, lower reaches of Olenyok River). Continuous stratigraphical section of the Pliensbachian and Toarcian is revealed for the first time in the north of East Siberia. Stratigraphiac position of the lower and upper boundaries of the Kurung Member of the Kelimyar Formation is specified. Stratigraphic range of the bituminous Kurung Member corresponds to the Kiterbyut Formation in the Regional Jurassic scale of Siberia.
