Settlements of the Amnya cultural type in the context of the Early Neolithic of North-Western Siberia

Purpose. The Stone Age settlement of Amnya I in North-Western Siberia represents the northernmost hunter-gatherer-fisher fort in Eurasia. Dating back to the beginning of the 6th millennium BC, this unique site enables the study of key innovations of the Neolithization process in the taiga zone, such as defensive structures, early pottery, and an increase in polished tools including arrowheads. Results. The Amnya cultural type also includes the nearby Kirip-Vis-Yugan-2 settlement, which shows close similarities with Amnya I in material culture however lacks fortifications. To follow up open questions, work on Amnya type sites was resumed in 2019. Plans of the sites, their layout and stratigraphy were clarified, and first palaeoenvironmental data was received. Radiocarbon dating of stratified contexts at Amnya I confirmed its Early Neolithic age. The settlement of Amnya II located just 50 m east of the fortifications was also dated. Originally attributed to later, Eneolithic times, the two new AMS dates date back to the beginning of the 6th millennium BC, indicating that Amnya I and II existed broadly contemporaneously. Palaeoenvironmental studies based on drillings in the adjacent peat bog show that at the time of settlement at Amnya I and II open water existed on the south of the hill fort, and the Amnya River was flowing on the north side. Thus, this place was comfortable for living and provided good conditions for fishing. Botanical macro-remains from cultural layers at Amnya I show that during the existence of the settlement, along with pine, deciduous trees - birch and alder, have grown in the area of the site, indicating a warmer climate, compared to current conditions. Conclusion. The studied archaeological settlements show the case of Neolithic innovations which testify to formation of special social structures and, most likely, appearance of the new population in the taiga zone of Western Siberia at the turn of 7th - 6th millennium BC.
