Applying sterols and bile acids as biomarkers for identifying human versus wild animals' faecal traces in cave sediments at archaeological sites
Faecal biomarkers are used to trace and identify the source of faecal matter at various types of archaeological sites. Until now, the focus has been centred on humans and domesticated animals. However, in caves, it's wild animals that play a role in the deposition of organic matter. To assess the participation of animals and humans at such sites through molecular markers it is crucial to recognize their biomolecular signature. We developed a data…
Faecal biomarkers as evidence of human presence in the caves of Kraków-Częstochowa Upland
This study investigates past human presence at cave sites by analysing faecal biomarkers—specifically sterols, bile acids and phosphorus-and compares the results with available archaeological data. The research concentrates on seven sites in the Kraków-Częstochowa Upland (S Poland): Biśnik Cave, Bramka Rockshelter, Ciasna Cave, Łabajowa Cave, Łokietka Cave, Sąspowska Zachodnia Cave, and Shelter in Smoleń III. It involved analysing sediment sample…

New Data for Asymmetric Core Reduction in Western Tian Shan Piedmonts: The Ertash Sai 2 Open-Air Site
This study describes a multi-proxy approach toward a newly discovered open-air loess site, Ertash Sai 2, located in the western piedmonts of the Tian Shan in Uzbekistan. Technological analyzes enabled the identification of an asymmetric core reduction scheme accompanied by a Levallois-like predetermined knapping scheme, along with the production of truncated-faceted pieces and burin-cores. Moreover, the results show a direct relationship between …

Potential impact of Holocene climate changes on camel breeding practices of Neolithic pastoralists in the Central Asian drylands: A preliminary assessment
Archaeological findings from the Neolithic open-air location Ayakagytma ‘The Site’, situated in the south-eastern part of the Kyzyl-kum Desert in Uzbekistan, can potentially shed new light on the camel domestication process in the Central Asian drylands and help to connect it to regional changes of paleoclimate. Detailed analyses of composition and 13 C isotopic ratios of fatty acids performed on potsherds from an archaeological horizon of a Kelt…
Technological study of the lithic materials from the site Wołkusz 3 in NE Poland. The concept of the preferential blades' production
The article aims to present the results of the technological analysis of the lithic artefacts from the site Wołkusz 3. This comprises a detailed characterisation of one of the two reconstructed flint knapping strategies described as the concept of preferential blades. The Wolkushian culture inventory consisting of almost 3000 pieces was subjected to the analyses. The collection includes the debitage products – cores, flakes and blades, as well as…
New evidence for mountain Palaeolithic human occupation in the western Tian Shan piedmonts, eastern Uzbekistan
This article presents preliminary results from mountain survey in the Chatkal Range in the western Tian Shan piedmonts, eastern Uzbekistan. In 2021, several new Palaeolithic sites were discovered, including a single, multi-layered, open-air site-Kuksaray 2-located near a flint outcrop. The authors' initial investigations have recovered a stone tool assemblage containing tools displaying both Middle Palaeolithic and Initial Upper Palaeolithic char…
Is there Initial Upper Palaeolithic in Western Tian Shan? Example of an open-air site Katta Sai 2 (Uzbekistan)
The paper presents the results of multidisciplinary studies on the open-air loess site Katta Sai 2 located in the western piedmonts of Tian Shan in Uzbekistan. Two archaeological horizons contain features associated with the Initial Upper Palaeolithic (IUP) - both Levallois and blade/bladelet volumetric technology, together with an Upper Palaeolithic toolkit. The cultural traits observed in Katta Sai 2 might have local roots dating back to MIS 5a…

Middle Paleolithic technological diversity during MIS 3 in the Western Tian Shan piedmonts: Example of the Katta Sai 1 open -air loess site
This paper aims to reconstruct the general knapping scheme in the Katta Sai 1 assemblage dated to around 40 kya. The site was excavated within a large -scale fieldwork project of interdisciplinary studies on Middle Paleolithic settlements in the western Tian Shan piedmont. The technological analyses allow the identification of a new variant of human adaptation in the regional Middle Paleolithic. The locally -collected river pebbles were knapped u…
Raw material procurement as a crucial factor determining knapping technology in the Katta Sai complex of Middle Palaeolithic sites in the western Tian Shan piedmonts of Uzbekistan
Searching of the Paleolithic Sites in the Akhangaran River Valley: History and Our Time
The article deals with the history of the study of the Paleolithic sites in the Akhangaran river valley (Eastern Uzbekistan) as well as the data obtained from the current research cycle. There are three zones of concentration of archaeological objects in the Akhangaran valley, on the basis of the materials of which it is possible to get an idea of the peculiarities of the Paleolithic development in the foothills and lowlands of the Tien Shan. The…
