Early Middle Pleistocene Fauna Of Fossil Rodents And Loess-Paleosol Series Of The Pekla Key Section (Taman Peninsula, Russia)

The early Middle Pleistocene which spanned from the Brunhes-Matuyama transition (772.9 ka BP, within MIS 19) till the beginning of the Likhvin Interglacial (424 ka BP, MIS 11) includes a number of interglacials and glaciations. Rodent species of the Tiraspolian faunal assemblage were found in the Chaudian fluvial deposits of the Cape Pekla section (northern coast of the Taman Peninsula). The evolutional level of the Pekla rodents are similar to those from the stratotype section of the Tiraspolian faunal assemblage in the Kolkotova Balka in Moldova (MIS 17) , which includes Eolagurus sp., Mimomys savini, Microtus (Terricola) arvalidens, Microtus (Alexandromys) ex gr. oeconomus and other species. The Pekla fauna also resembles the rodent fauna from famous English West Runton Freshwater Bed locality formed during the Cromerian Interglacial II and some other East and West European faunas. In the current work the entire loess-paleosol sequence of the Pekla section was described with five paleosols from the Middle to the Late Pleistocene. The sequence reflects the complexity of climatic fluctuations from the early Middle Pleistocene to the Holocene.
The palaeoenvironment of the Central Russian Plain during the last part of Valdai Glaciation based on small mammal datafrom the Late Palaeolithic site Byki 7 (Seim R. basin), 2022

Steppe species definitely prevail and include Ochotona pusilla, Marmota bobac, Spermophilus sp., Spalax microphthalmus, Ellobius talpinus, Lagurus lagurus and Lasiopodomys (Stenocranius) gregalis. Tundra species (collared lemming and Siberian lemming) are only represented by a small amount of remains. The lack of forest dwellers in the Byki 7 small mammal assemblage indicates of the absence of a continuous forest zone on the Central Russian Plain during the end of the Valdai glaciation. The Eurasian geographical distribution of the Rodentia and Lagomorpha species represented in the Byki-7 assemblages, have been reconstructed for the period of deposition of the site. Radiocarbon dates indicate that the multilayer Late Palaeolithic Byki 7 site correlates with the second part of the Valdai Glaciation Maximum cooling (LGM) (22-17 ka BP). Based on the small mammal data the former palaeoenvironmental conditions of the non-analogue periglacial tundra-steppe are reconstructed.

A more complex sequence of natural events and small mammal faunas is known from eastern Europe during the late Middle Pleistocene than from western Europe. The interval between the Likhvin (Holstein) Interglacial and the Dniepr (Saalian) Glaciation include a further two climatic cycles as compared to the western European sequence. Sediments of most of these cycles contain small mammal localities. The most secure correlation is between the Likhvinian and Holsteinian micromammalian faunas.

The East Caucasian Forelands during the Quaternary: Deposits and Environments

The Quaternary deposits (~160 m thick) are located in the middle reaches of the Kuma River (East Caucasian Forelands) near Otkaznoye Village (44°19' N, 43°51' E). All analyses were carried out for two vertical profiles. Longest Profile I presents ~140 m thickness penetrated by a borehole on the interfluvial plateau (at ~245.5 m a.s.l.). Three sedimentary cycles are exposed here. The first cycle contains alluvial deposits (127.6–136.4 m) and subaerial strata including three well-developed paleosols (115.8–127.6 m); the second cycle presents alluvium (112.8–115.8 m) and subaerial formations with two paleosols (107.35–112.8 m). The third cycle presents alluvial-proluvial series (64.9–107.35 m) and a thick member of loessial deposits with 6 paleosols (1.4–64.9 m). The Matuyama-Brunhes reversal (~0.778 Ma) was found at 75 m a.s.l. The Jaramillo event was recognized within the Matuyama zone in the 103.0–113.0 m interval. According to pollen data, deposition of this interfluvial series took place during the Early–Upper Pleistocene and terminated in the formation of thick upper loess, which was deposited during the Dnieper Glaciation and during the first half of the Mikulino (Eem) Interglacial. The results obtained from Upper Pleistocene deposits were completed by analysis of Valdai sediments of lower terraces of the Kuma R. Palynological characteristics of the deposits located below the Brunhes-Matuyama boundary are fragmentary and permit reconstruction of only some stages of the Early Pleistocene. Two phases were distinguished in the deposits related to the Jaramillo event. The first phase was characterized by cooling and aridization (steppe landscapes). The second phase was characterized by warming and increasing of humidity (broadleaf forests). Comprehensive palynological information provided a basis for reconstructing of flora evolution, vegetation and climate changes for 15 interglacial and cold stages of the Brunhes Chron. For the most part of this period the Terek-Kuma Lowland was occupied by interglacial forest-steppes or by periglacial forest-steppes. For the first time in Middle Pleistocene history (Likhvin Interglacial, MIS 11, Paleosol Complex IV) steppes became dominant here. More than a hundred of small mammal remains from PC IV were studied (Spermophilus pygmaeus, Spalax microphtalmus, Cricetus cricetus, Cricetulus migratorius, Eolagurus luteus volgensis, Lagurus lagurus, Microtus ex. gr. arvalis-socialis). Rodent fauna was attributed to Singilian-Gunkovian mammal assemblage and very characteristic to steppe landscapes. Dry steppes and semi-deserts that appeared occasionally in the Middle Kuma basin at some warm Early Pleistocene intervals assumed dominant importance during Mid-Late Pleistocene, firstly at the cryoxerotic stage of the Dnieper ice age (~MIS 6), and later at the same stage of the Valdai glacial epoch (~MIS 4-2). The vegetation at those stages were typical periglacial. Forest landscapes were dominant during five intervals. At the Muchkap Interglacial (~MIS 15) prevailed broad-leaved forests with participation of subtropical species. Broad-leaved forests (mesophytic or xerophytic) occupied the region during the interglacials corresponding to ~ MIS 9, MIS 7 and MIS 5. Some phases of the Kaluga cold epoch (~MIS 10) were marked by dominance of spruce and Siberian stone pine forests. The named five “forest” phases correspond to climate-induced rises of Caspian Sea level during the Mid-Late Pleistocene. Keywords: Quaternary, East Caucasian Forelands, environments.

The fauna most likely is of Middle Pleistocene age.

The faunas of this evolutional level existed during the Early Middle Pleistocene and could be correlated with MIS 17.

The received data permit to reconstruct the climatic-environmental condition during the Early Khvalynian transgression in the Manych basin. This transgression was dated by 14 C in the interval between 16–12 kyr BP. As a result of the formation of a Cascade of Eurasian Basins for the first time in the Late Pleistocene Caspian waters of the Khvalynian Sea had flooded to the Manych depression and the Manych-Kerch strait was originated during that time. The marine mollusks appeared in the Manych basin together with Caspian Sea water. The salinity of Khvalynian basin was close to the same of the Caspian Sea (10–12%) and the water temperature was lower than recent one, what confirms by the fact that mollusk’ shells were two-three times smaller than the modern ones of the same species. The analysis of the ...

Tarasov, who summarized data on paleoecology and habitat conditions on this site in a number of publications. However, the stratigraphic position of the deposits containing the cultural layer remained rather uncertain due to the fact that in the sections of the site it was not possible to identify the reference loess-soil horizons and data on the age of the cultural layer were not obtained. A comprehensive study of the site, renewed since 2007 under the direction of archaeologist A. K. Ocherednoi in the frame of the Verkhnyaya Desna expedition of the Institute for the History of Material Culture RAS, permit to detail the deposition rhythmic during the Late Pleistocene and the stratigraphic position of the cultural layers in different parts of the site. By received 14 C data, the site was inhabited in the range of 28.5–36.0 cal kyr BP (calibrated dates), i.e., belongs to the end of the Valdai megainterstadi...
