Abstract

Conchostracans (Crustacea) from the Induan deposits of the Tiryakh-Kobyume section (southern Verkhoyansk region) were studied. We identified the following seven conchostracan species belonging to five genera: Pseudestheria Raymond, 1946; Euestheria Deperet et Mezeran, 1912; Sphaerestheria Novojilov, 1954; Lioestheria Deperet et Mezeran, 1912; Wetlugites Novojilov, 1958. Most of the previously identified species in the Tiryakh-Kobyume region (“Pseudestheria sibirica”, “Ps. tumaryana”, “Ps. kashirtzevi”, and “Sphaerestheria aldanensis”) were described in the middle of the 20th century from the basal Triassic in the western Verkhoyansk region (Balbuk section). Revision of these species with the use of modern methods of conchostracan classification is needed.

Keywords: conchostracans, Early Triassic, southern Verkhoyansk region

Acknowledgments. We thank A.N. Kilyasov and I.V. Budnikov for their assistance during the sampling procedures and description of the section.

The study was supported by the subsidy allocated to Kazan Federal University for the state assignment no. 671-2020-0049 in the sphere of scientific activities. The conchostracan study was funded by the Russian Science Foundation (project no. 19-17-00178).
