We investigated temporal variation in carbon and oxygen isotopic values extracted from dental enamel of <em>U. spelaeus</em> specimens from multiple stratigraphic units within Scladina Cave, Belgium, in conjunction with dental morphology, which we quantified using 2D geometric morphometrics to test the hypothesis that Pleistocene climatic changes impact phenotypic variation and feeding ecology of extinct megafauna. Size and shape of the second lower molar differ in cave bears across several stratigraphic units, even for short temporal gaps between sediment depositions (∼3ky). <em>Ursus spelaeus</em> from Scladina exhibited low δ¹³C values comparable to that of contemporary herbivores from the same sequence, suggesting an herbivorous diet for the species throughout the temporal sequence. Climatic change had an impact on size and diet, with larger dentition relating to previously suggested colder environmental periods. The existence of these periods was further supported by our δ¹³C and δ¹⁸O measurements. Warmer periods were indicated by higher δ¹⁸O values and correlated with lower δ¹³C values indicative of a diet enriched in plant sources from more forested environments. The environmental variation through the studied sedimentary units of Scladina Cave is discussed and interpreted alongside previously produced palynological results for units herein. Our results support previous suggestions that cave bears from Scladina Cave had a herbivorous diet, while further strengthening the current stratigraphic interpretation of the cave.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"743 ","pages":"Article 109914"},"PeriodicalIF":1.9,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such poor temporal constraints have hindered various analyses of Pinjor age fauna, particularly those focused on understanding Pleistocene changes and fluctuations in the ecology and climate and its possible impact on faunal and hominin populations in the region. Given the antiquity of the sediments of the Pinjor Formation, most methods of absolute dating have proven to be inconclusive in yielding any results generally due to temporal and sedimentary constraints. In this paper we use Electron Spin Resonance (ESR) dating to derive chronometric dates from fossilised teeth with a known stratigraphic association and propose a preliminary division of Pinjor age fossil localities into three time bins, 2.58–1.77 Ma, 1.8–1 Ma and 0.9–0.4 Ma.

The decline in %bSi content and XRF-based Si/Al ratios during the abrupt cold events of MIS 3 and MIS 2 suggests a reduction in upwelling intensity, likely driven by a shift in the position of the Intertropical Convergence Zone (ITCZ) and the North Pacific High (NPH), in response to the continued expansion of the Laurentide Ice Sheet until ∼16.5 kyr.

Its complex hydrography is mainly influenced by an interplay of multiple ocean and atmospheric processes, i.e., inter-oceanic heat exchange (Indonesian throughflow; ITF), ocean-atmosphere interactions (Indian Ocean Dipole; IOD and El Niño-Southern Oscillation; ENSO) and seasonal monsoon circulations, at varying time-scales. However, the associated feedbacks of these climatic components and the impact on EEIO hydrography over millennial time-scales remain unclear, thus highlighting the need for further investigation. Here, we present well-dated records of the planktic foraminiferal proxies (% <em>Globigerina bulloides</em>, % symbiont-barren and symbiont-bearing species) and stable oxygen isotope (δ¹⁸O of <em>Globigerinoides ruber</em> (r) and <em>Pulleniatina obliquiloculata</em> (o), and Δδ¹⁸O_r-o) at multi-centennial to millennial scale resolutions from a spade core SC-04B, retrieved from a specific location of the EEIO (8.40°S, 98.00°E). The core spans the late deglacial to middle Holocene period (12.8–4.7 ka). Using faunal and isotope proxies, we reconstructed changes in surface hydrography, productivity, and the upper water-column structure during 12.8–4.7 ka, and explored their potential links with the ITF, IOD-like mean state, and South Asian Monsoon (SAM) variability. We document the increased influence of surface ITF during 12.8 to ∼9.8 ka that switched to thermocline ITF during ∼9.8 to 4.7 ka. When compared with existing oceanic and land-based paleoclimate records from the Indian Ocean and adjacent continents, our faunal proxies suggest an intensification of the southeast (SE) monsoon winds and upwelling-induced surface productivity in the EEIO during the periods of 12–9.2, 8.0–7.3, 6.4–5.6, and 5.2–4.7 ka. These intervals correspond to conditions similar to a positive IOD (pIOD)-like mean state in the tropical Indian Ocean, when SAM was also intensified. In contrast, during 12.8–12, 9.2–8.0, 7.3–6.4, and 5.6–5.2 ka, weakened SE monsoon winds led to increased precipitation-induced stratification, creating surface conditions similar to a negative IOD (nIOD)-like mean state, which suppressed surface productivity in the EEIO. Further, we record four distinct intervals (∼6, ∼8.2, ∼10.5, and ∼12 ka) of low % <em>G. bulloides</em> abundance and corresponding low values of Δδ¹⁸O_r-o, which appear to coincide with the cold phases in the North Atlantic [Bond Events (BEs) 4, 5, 7 and Younger Dryas (YD)]. We think that these changes were possibly linked with the intensified northwest (NW) monsoon winds and could have been modulated by the North Atlantic cold events potentially through atmospheric teleconnections.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"743 ","pages":"Article 109917"},"PeriodicalIF":1.9,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At Gombore I (Melka Kunture, Ethiopia), lithic materials attributed to Level B are often associated with flood-prone or riparian zones, and thus subject to post-depositional alterations such as aeolian abrasion and trampling. Additionally, the diversity and nature of raw materials, mainly volcanic rocks like obsidian and basalt, further complicate use-wear studies. In this study we present preliminary findings from the Gombore IB lithic assemblage, which is attributed to the ESA, with significant levels associated with the Acheulean technocomplex. Initial sampling, based on visual inspection, prioritized artefacts deemed suitable for traceology. However, macro- and microscopic analyses revealed extensive surface alterations, limiting the preservation of use-wear traces and rendering traditional analysis unviable. Our research therefore focused on developing a broader analytical framework which could use these preservation issues for interpretations on site formation processes in the archaeological record. By employing dedicated experimental protocols to compare with the archaeological assemblage, this study establishes an initial use-wear pattern associated with post-depositional alteration. The lithic assemblage from Gombore IB offers valuable insights, which we apply to interpret the site's formation processes.
