Stratigraphic Subdivisions of the Lower Triassic of South Primorye Region. Article 3. First Findings of Euflemingites prynadai and Shimanskyites shimanskyi (Ammonoidea) in the SMID Section

Stratigraphically important early Olenekian ammonoids are found for the first time in the SMID section (outskirts of the town of Artem, southern Primorye): Euflemingites prynadai (Kiparisova), Shimanskyites shimanskyi Zakharov et Smyshlyaeva, Parussuria semenovi Zakharov, and Xenoceltites aff. variostatus Brayard et Bucher. The scheme of zonal subdivisions of the lower substage of the Olenekian Stage of this region is refined on the basis of new paleontological data.
