Increased flooding caused by global warming threatens the safety of coastal and river basin dwellers, but the relationship of flooding frequency, human settlement and climate change at long time scales remains unclear. Paleolithic, Neolithic and Bronze Age cultural deposits interbedded with flood sediments were found at the Shalongka site near the north bank of the upper Yellow River, northeastern Tibetan Plateau. We reconstruct the history of overbank flooding and human occupation at the Shalongka site by application of optically stimulated luminescence and radiocarbon dating, grain size, magnetic susceptibility and color reflectance analysis of overbank sediment and paleosols. The reliability of OSL dating has been confirmed by internal checks and comparing with independent 14C ages; alluvial OSL ages have shown a systematic overestimation due to poor bleaching. Our results indicate that the Yellow River episodically overflowed and reached the Shalongka site from at least ~ 16 ka and lasting until ~ 3 ka. Soil development and reduced flooding occurred at ~ 15, ~ 8.3–5.4, and after ~ 3 ka, and prehistoric populations spread to the Shalongka site area at ~ 8.3, ~ 5.4, and ~ 3 ka. We suggest that climate change influenced the overbank flooding frequency and then affected prehistoric human occupation of the Shalongka site.

The chronology of the Mesolithic, Neolithic, Aeneolithic, and Bronze Age sites in the Trans-Urals (Russia) was studied, and a framework for previously established cultural complexes is suggested based on 153 radiocarbon dates. In this new chronological model, the Mesolithic is dated to ~10,000–6500 cal BC; the Neolithic complexes exist at ~6500–3800 cal BC; the Aeneolithic is dated to ~4300–2800 cal BC; the Early Bronze Age spans ~2500–2100 cal BC; and the Late Bronze Age can be preliminary assigned to ~1600–1100 cal BC.

Does the riding of horses necessarily go with the emergence of Eurasian pastoralism? Drawing on their fine sequence of animal bones from Begash, the authors think not. While pastoral herding of sheep and goats is evident from the Early Bronze Age, the horse appears only in small numbers before the end of the first millennium BC. Its adoption coincides with an increase in hunting and the advent of larger politically organised groups.
