New Data on the Distribution of Southern Forests for the West Siberian Plain during the Late Pleistocene: A Paleoentomological Approach
Published 2023-01-01“…Subfossil remains of insects and branchiopod crustaceans (Cladocera and Notostraca) found in three late Pleistocene deposits in the Novosibirsk region in the vicinity of the village of Suzun have been described. The calibrated radiocarbon dates for these deposits were 24,893–25,966 cal BP (Suzun-1), 20,379–20,699 cal BP (Suzun-2), and 27,693–28,126 cal BP (Nizhny Suzun), which correspond to the onset of marine isotope stage 2 (MIS 2). …”

Frequent activity on Vulcano (Italy) spanning the last 80 ky: new insights from the chemo-stratigraphy of the Brown Tuffs
Published 2020“…The distinctive chemical groupings observed within the glass analyses, both temporally and spatially, allow us to fingerprint the three main stratigraphically defined macro-units in which the BT succession can be sub-divided using prominent tephra marker beds, the Ischia Tephra (Monte Epomeo Green Tuff; 56 ky) and Monte Guardia pyroclastics from Lipari (herein radiocarbon dated to 27–26 ky). The Lower (80–56 ky; LBT), Intermediate (56–27 ky; IBT) and Upper BT (here dated at 24–6 ky; UBT) macro-units display K-series volcanic glasses ranging from basaltic trachy-andesites, through trachy-andesites, to more evolved trachytes, all consistent with an origin on Vulcano. …”

A series of radiocarbon dates obtained for the settlement of Tolum-1 and other sites of the Enyi type in the north of Western Siberia, as well as the technical and technological characteristics and morphology of the stone inventory of the settlement under consideration, and a wide range of analogies leave open the possibility of attributing the structure No. 3 to the Eneolithic Period, within the span of the calibrated dates in the interval of 3600–2600 BC.…”
