We consider the distribution of dinocysts of the genus Pseudokomewuia in the stratotype section of the Zhuravka Horizon (Zashchitino Village) and in the section of borehole 13 (Chelyuskintsev Village), which exposes the Turtas, Abrosimovka, and Beshcheul Formations. Similar compositions...

... change, involving the flora (extinction of the forest mesophilic Turgai flora and formation of the forest-steppe post-Turgai flora). Three stages of the development of the Turgai flora – Tagan, Kas’kovka, and Isakovka – have been outlined by paleobotanical data generalized over the Beshcheul Horizon...

The compiled paleomagnetic section, which includes seven regional horizons and same-named formations (Oligocene Atlym, Novomikhailovka, and Zhuravka Formations and Neogene Abrosimovka, Beshcheul, Tavolzhan, and Novaya Stanitsa Formations), was compared with the Cenozoic polarity scale...

..., they consist of four formations: Abrosimovka, Beshcheul, Tavolzhan, and Novaya Stanitsa. These sediments are widespread on the southern West Siberian Plain. The Lower Neogene–Lower Miocene. The Abrosimovka Formation overlies the Zhuravka Formation (56.6–50 m) with erosion and is made up of lacustrine...

... Siberian Plain [ 2 ], we recognized marine deposits of the Gan’kino, Lyulinvor (BH-15), and Tavda (BH-2, BH-4, BH-10, and BH-15) Formations ( Fig. 3 ). The Paleogene continental deposits include the Atlym, Novomikhailovka, and Zhuravka Formations. The Miocene includes the Abrosimovka, Beshcheul, Tavolzhan...

... of the Kas’kovka floral level [e.g., 4 , 11 ]. Later on, rich and quite typical floras of this level were identified not only in the Kas’kovka Formation per se but also in the lower beds of the Beshcheul’ and Suzun Formations [ 16 ]; in total, they are now known in more than 70 occurrences. The collections...

... is dated late Middle—Upper Eocene (upper Lutetian—Bartonian—Priabonian). We describe eight palynological assemblages from the continental Paleogene and Neogene deposits and substantiate the establishment of the Zhuravka, Abrosimov, Beshcheul’, and Tavolga Formations in the boreholes. Three stages...

... ]. The age of the deposits is the Lower Miocene. The basalt deposits of the Abrosimovka Formation which are still characterized by the Late Oligocene spore-and-pollen complex are absent from BH-9. The Beshcheul Formation is recognized in the range 124–90 m. The deposits are represented by finely...

In the late Early–Middle Miocene (21–18 Ma), a new stage of lacustrine–alluvial sedimentation began (Beshcheul Formation...

A typical spore-pollen assemblage of the first half of the Middle Miocene is found as the Kozhevnikovo flora in the lower section of the Beshcheul...

They indicate a significantly warmer climate, with average annual temperatures being up to 10° higher than they are now...

Most of these formations and sequences lack stratotype sections and remain poorly constrained as to the stratigraphic position, range, faunas, and relations of specific geological bodies...
