Abstract. During the Late Pleistocene, stadial and interstadial fluctuations affected vegetation, fauna, human groups that were forced to cope with these pronounced climatic environmental changes in time space. These especially abrupt during Marine Isotopic Stage (MIS) 3. However, little is still known about local regional conditions experienced by hominins Europe. Here we reconstruct trends northern Iberia considering stable isotopic composition of ungulate skeletal tissues found archaeological deposits dated between 80 15,000 cal BP. The carbon oxygen preserved carbonate fraction tooth enamel provides a reliable high-resolution proxy food water consumed animals, which indirectly related environment, climate, allowing us estimate paleotemperatures rainfall data. This study presents 44 bovine, equid, cervid teeth from five sites Vasco-Cantabrian region (El Castillo, El Otero, Axlor, Labeko Koba, Aitzbitarte III) one Mediterranean area (Canyars), where evidence attested Mousterian Magdalenian. isotope values reflect animals feeding on C3 plants mix-feeder diet mainly developed open environments. value ranges point differentiated ecological niches for equids bovines, Aurignacian region.

The Iberian Peninsula is a key region for unraveling human settlement histories of Eurasia during the period spanning decline Neandertals and emergence anatomically modern humans (AMH). There no evidence occupation in central Iberia after disappearance ~42,000 years ago until approximately 26,000 ago, rendering "nobody's land" Aurignacian period. Abrigo de la Malia provides irrefutable settlements dating back to 36,200 31,760 calibrated before present (cal B.P.) This site also records additional levels around 32,420 26,260 cal B.P., suggesting repeated this territory. Our multiproxy examination identifies change climate trending toward colder more arid conditions. However, climatic deterioration does not appear have affected AMH subsistence strategies or their capacity inhabit region. These findings reveal ability groups colonize regions hitherto considered uninhabitable, reopening debate on early Upper Paleolithic population dynamics southwestern Europe.

The existing radiocarbon (14C) dating framework for Lagar Velho is broadly consistent but provides limited constraint on several geoarchaeological complexes (GCs) and does not favour detailed chronological comparisons across all sectors of the site; including stratigraphically disconnected child burial complex in east area broader archaeological sequence central-west area. In this study, we undertake a complementary assessment Rock Shelter using single-grain quartz OSL, TT-OSL combined U-series/ESR fossil teeth, with aim establishing more comprehensive reconstructions events placing human occupation firmer regional climatic context. Expanding original also compare published 14C datasets against widely used sample quality indicators (i.e., organic preservation contamination proxies) to ensure reliable our new luminescence ages.

Understanding the factors that influence geographic range of extinct megafaunal species is crucial for reconstructing their ecology and extinction dynamics. For extant herbivores, it has been demonstrated large body mass provides potential greater range. Allometric scaling relationships are observed in placental mammals but have not well-established marsupials, particular, marsupial megafauna. Here, we employ a phylogenetic generalised least squares regression model using macropodids to estimate home ranges individuals from genus Protemnodon. The predicts mean 11.6 ± 5.8 km 2 This prediction, centred on Mt Etna caves, incorporates several distinct geological features with variable, known 87 Sr/ 86 Sr isotope ratios. Fossil Protemnodon recovered cave deposits at returned values similar host limestone, which systems formed, broader Mount Alma Formation. similarity suggests foraged close where they were fossilised, indicating smaller than predicted. Smaller body-mass unexpected, attributed unique combination individual behaviour, diet and/or locomotion regime within stable rainforest environments. Our results suggest that, foraging megaherbivores may be more strongly associated environmental quality rather mass. New in-situ uranium-thorium single-grain TT-OSL ages refine, agreement with, previous interpretations chronology, rainforest-adapted fauna persisted until 280 ka. We propose small environment, such as rainforests, predisposed these megafauna after 280ka, driven by an increasingly dry unstable climate. underscore need regionally specific biologies individuals, populations when considering pathways Pleistocene fauna.

Aquatic environments are highly dynamic. They characterized by rapid and often unpredictable transformations driven sea-level fluctuations, climate change, tectonic activity, anthropic land-and-sea use practices that result in large-scale environmental shifts. Globally, archaeology has documented how people adapt respond to these changes altering subsistence strategies, settlement patterns, travel routes, technologies meet the challenges of a constantly transforming aquascape. Coastal regions, particular, have both challenged sustained human populations, offering abundant resources while also requiring significant adaptability response regular and, at times, substantial sea level fluctuations from terminal Pleistocene throughout Holocene. Using an interdisciplinary approach pairs coastal geomorphology archaeology, we investigated Mid- Late Holocene development barrier island southeast Victoria, Australia–the which prompted wider inshore ecosystem transformations. Results archaeological excavations demonstrate responded flexibly adjusting their lifeways strategies over short time-scales through firing landscape, shaped surrounding ecosystems return. Understanding populations navigated past changes, immediate adaptive responses long-term cultural transformations, provides valuable insights into resilience societies face uncertainty.
