Wood artefacts rarely survive from the Early Stone Age since they require exceptional conditions for preservation; consequently, we have limited information about when and how hominins used this basic raw material1. We report here on earliest evidence structural use of wood in archaeological record. Waterlogged deposits at site Kalambo Falls, Zambia, dated by luminescence to least 476 ± 23 kyr ago (ka), preserved two interlocking logs joined transversely an intentionally cut notch. This...
Abstract Pleistocene hominin dispersals out of, and back into, Africa necessarily involved traversing the diverse often challenging environments of Southwest Asia 1–4 . Archaeological palaeontological records from Levantine woodland zone document major biological cultural shifts, such as alternating occupations by Homo sapiens Neanderthals. However, Late Quaternary cultural, environmental vast arid that constitutes most remain scarce, limiting regional-scale insights into changes in...
ABSTRACT Increasing evidence suggests that bifacial technology (Acheulian, Mode 2) arrived in Europe during the early Middle Pleistocene, i.e. significantly earlier than previously proposed. In northern France and Britain, much of age attribution for these assemblages has been based on biostratigraphy lithostratigraphy rather absolute dates. This study presents a systematic application electron spin resonance (ESR) dating sedimentary quartz ESR/U‐series fossil tooth enamel to key Acheulian...
The African Middle Stone Age (MSA, typically considered to span ca. 300-30 thousand years ago [ka]), represents our species' first and longest lasting cultural phase. Although the MSA Later (LSA) transition is known have had a degree of spatial temporal variability, recent studies implied that in some regions, persisted well beyond 30 ka. Here we report two new sites Senegal date end around 11 ka, youngest yet documented Africa. This shows this phase into Holocene. These results highlight...

The geomorphology and Quaternary history of the River Orontes in western Syria south-central Turkey have been studied using a combination methods: field survey, differential GPS, satellite imagery, analysis sediments to determine provenance, flow direction fluvial environment, incorporation evidence from fossils for both palaeoenvironments biostratigraphy, uranium-series dating calcrete cement, reconciliation Palaeolithic archaeological contents, uplift modelling based on terrace height...
The nature of human dispersals out Africa has remained elusive because the poor resolution paleoecological data in direct association with remains earliest non-African people. Here, we report hominin and non-hominin mammalian tracks from an ancient lake deposit Arabian Peninsula, dated within last interglacial. findings, it is argued, likely represent oldest securely evidence for Homo sapiens Arabia. indicates a well-watered semi-arid grassland setting during movements into Nefud Desert...
A weakening of the Atlantic Meridional Overturning Circulation (AMOC) is predicted to occur under multiple scenarios future warming. However, effect meltwater from a decaying Greenland Ice Sheet (GrIS) on AMOC uncertain. Using basin-wide network North sediment cores, we show that largescale melting GrIS during previous interglacial (Marine Isotope Stage 11c (MIS11c); 397 – 427 ka) led millennial-scale, 30±15% and an associated abrupt 2 7⁰C cooling event over subpolar Atlantic. Furthermore,...
Abstract Immature and mature calcretes from an alluvial terrace sequence in the Sorbas basin, southeast Spain, were dated by U-series isochron technique. The immature horizons consistently produced statistically reliable ages of high precision. typically unreliable but, because linear trends dataset low errors associated with each data point, it was still possible to place a best-fit through produce age uncertainties. It is, however, only prove that these have geochronological significance...
