Kovrizhka IV has been identified as a series of seasonal residential camps on the beach line near a cliff of a rocky cape protruding into the Vitim River. Remains of dwellings were excavated in cultural horizons 6, 3 B, 3/2, 2G and remains of a hearth feature in cultural horizon 2 B. In two cases, the living area colored or sprinkled with ochre pieces. In summary, the existing data characterize a stable, reproductively successful lifestyle in terms of adaptation and survival to the conditions of the LGM lasting approximately 500 years. The lithic processing techniques documented in the contexts of the production of microblades, macroblades, coarse prismatic blades, flakes, facial finishing of bifaces and unifaces, and judging by the graphite pendant, grinding and drilling techniques. The Yubetsu technique of microblade pressure knapping was known to the people at Kovrizhka IV, but another technique, called the Kovrizhka method, much more opportunistic in terms of blank choice and core rotation, was dominant. The rest of the lithic production at Kovrizhka IV demonstrates the cumulative nature of the preservation of traditions dating back to the Early Upper Paleolithic (macroblades), and the Middle Upper Paleolithic (coarse prismatic blades) of Siberia. The main corresponding cultures are identified as the Studenoye culture of the LUP in southern Transbaikalia and the Dyuktai culture of Yakutia. In general, the lithic industry, and especially the technique of pressure knapping microblades, is characterized as a demonstrable continuity from Kovrizhka IV to sites of the Final MIS-2 of the Baikal-Patom Highlands such as Bolshoi Yakor I, Avdeikha, and Kovrizhka III. This culture is portrayed as a local adaptive set, contributing to the general ideas about the culture of the early LUP of Northeast Asia. In terms of dwelling features, toolkits, microblade production, and anthropomorphic figurines, Kovrizhka IV is unique for the whole of North Baikal Siberia, and makes a significant contribution to the general panorama of late Upper Paleolithic Northeast Asia.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"748 ","pages":"Article 109970"},"PeriodicalIF":1.8,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145106999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This layer of osteological material is overlain by relatively thick clayey sediments, again with a number of animal bones dated consistently to MIS 3, representing a rapid erosional phase. This erosional phase is likely associated with the transition between MIS 3 – MIS 2. MIS 2 itself includes one of the coldest and driest periods of the Last climatic cycle, i. e. Last Glacial Maximum (LGM), which is represented in the cave record by redeposited loess showing signs of freezing. The onset of the Holocene is marked by a continuous layer of sinter.

Here, we present an archaeobotanical assemblage consisting of fruit and seed remains from the regionally terminal Paleolithic (8740 ± 30 BP) Tangzigou site in western Yunnan. Our taxonomic identification shows that the archaeobotanical assemblage is poor in diversity with only four taxa, i.e., <em>Celtis</em> sp.

However, the full picture of plant exploitation by the Tangzigou people cannot be gained only from the low abundance and diversity of plant remains at the site itself. Based on what is known of the practices of hunter-gatherers today, most fruits and seeds were probably eaten by Tangzigou people during the course of foraging trips, with only a small fraction being carried back to the site for processing and consumption. The fruit stone remains of <em>C. axillaris</em> have been processed with fire accidently or intentionally; the intentional fire-processing was probably for consumption of the seeds inside, which is compatible with the processing of animal foods with fire by the Tangzigou people. Our study brings to light the possible incorporation of plant food resources into the diet of the latest Paleolithic Tangzigou people who are suggested to have lived under a warm subtropical climate.

Via regional correlations of palaeomagnetic secular variation we date the deglaciation of coastal Estonia. The decay of Late Weichselian ice from Estonian territory between about 14.7 and 12.7 cal ka BP was followed by extensive proglacial bodies of water, which developed in accordance to the receding ice margin and opening of new drainage routes. This is reflected in a wide distribution of clastic varved clays. Using visual and numerical methods we correlate two varve sequences from the Pärnu basin representing previously established 584-varve-year chronology and a new 532-varve-year sequence from the Vigala basin. Our analysis indicates that varve formation in the ice-proximal Vigala basin commenced approximately 140 years later than in the more distal Pärnu basin, yielding a combined local chronology of about 670 varve years. Natural remanent magnetization relative declination measured from the studied three varve records reveal an initial continuous eastward shift of approximately 90° during the first 400 varve years, after which values stabilize. Regional correlation of these palaeo secular variation records dates the clay accumulation in western Estonia to between ca 14.0 and 13.3 cal ka BP.
