We investigated ecological attributes of fossil mammals during the middle to late Miocene (17.5–8.5 Ma) in the western Mojave region of North America to evaluate the response of herbivorous ungulates to paleoenvironmental changes. Herbivores may utilize the same food resources across generations, relying on relationships with vegetation and habitats established over multiple generations. We employed stable isotopes of carbon and oxygen from ancient soils and herbivore tooth enamel to evaluate changes in vegetation and herbivore diets. We compiled isotopic data from published studies of three sequences from the warm Miocene Climatic Optimum and added new data from the Dove Spring Formation, which formed during the cooler Middle Miocene Climatic Transition. Herbivorous ungulates exhibited dietary fidelity for nearly nine million years, selectively consuming C₃ plants even as C₄ vegetation became more prevalent on the landscape. High oxygen stable isotope ratios in comparison to equids suggest that ancestral antilocaprids and camelids were likely facultative drinkers. These findings reveal enduring dietary preferences that enabled these herbivores to persist amid the profound environmental transitions of the Miocene.</div></div>","PeriodicalId":19928,"journal":{"name":"Palaeogeography, Palaeoclimatology, Palaeoecology","volume":"673 ","pages":"Article 113013"},"PeriodicalIF":2.6,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This area is located in the western part of the Jiangnan Orogen of the South China Block. Secondary ion mass spectrometry (SIMS) U<img>Pb zircon dating of the Xiamalian basalt, Youziping gabbro, and Mahai clinopyroxenite yielded concordia ages of 786.0 ± 5.6 Ma, 788.9 ± 4.8 Ma, and 780.1 ± 4.7 Ma. Geochemically, the Ximalian basalt and Tangtou clinopyroxenite, as well as three gabbroic rocks, have arc-like geochemical affinities characterized by moderate light rare earth element (LREE) enrichment (La_N/Yb_N = 2.79–9.45), pronounced negative Nb<img>Ta anomalies, and relatively low Nb/La ratios (with an average of 0.52). They have variable εNd(t) (−4.5 to 3.9) and positive εHf(t) (6.5–8.5) values. We thus conclude that these rocks were derived from the mantle wedge in a subduction setting via partial dehydration melting of the lithospheric mantle metasomatized by dehydrated fluids. In contrast, the Mahai clinopyroxenite exhibits ocean island basalt (OIB)-like signatures, including LREE enrichment (La_N/Yb_N = 11.87–22.25), a lack of negative Nb, Ta, and Ti anomalies; and positive εNd(t) (0.5–1.5, with one exception of −2.9) and εHf (t) (3.0–3.5) values. We infer that the Mahai clinopyroxenite was generated by partial decompression melting of the upwelling asthenospheric mantle in an extensional setting. Based on the regional geology, as well as the results of this study and previous publications, we conclude that the arc-type rocks analyzed in this study were generated under geodynamic processes triggered by the rollback of the subducted slab in a subduction setting. The OIB-like rocks were related to the break-off of the rolled-back slab, which created an extensional setting and enabled asthenospheric upwelling and partial melting.</div></div>","PeriodicalId":19928,"journal":{"name":"Palaeogeography, Palaeoclimatology, Palaeoecology","volume":"673 ","pages":"Article 113008"},"PeriodicalIF":2.6,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Qiongdongnan Basin in the South China Sea provides valuable geological records for reconstructing the paleoenvironmental conditions of the western Pacific during the late Oligocene to early Miocene. In this study, we conducted cyclostratigraphic and paleoclimatic analyses using high-resolution geophysical well-logging data, planktic foraminifera, and sporopollen from Well Ls33a. The power ratio accumulation (PRA) method indicates that among various geophysical logging parameters, natural gamma-ray (GR) data exhibit the highest sensitivity. Time series analysis reveals astronomical signals in the GR data, which were further validated through objective statistical methods such as TimeOpt, COCO, and PRA. By calibrating the interpreted 405-kyr eccentricity cycle, we developed a floating astronomical timescale spanning approximately 7.32 million years. Subsequently, based on the preliminary chronological framework derived from planktic foraminiferal biostratigraphy (∼28.4 Ma–21.12 Ma) and the La2010d theoretical astronomical solution, we established an absolute astronomical timescale for the 3547–3934 m interval of Well Ls33a, covering 28.55–21.23 Ma. Within this astronomical timeframe, we reconstructed sea-level fluctuations in the study area from the late Oligocene to early Miocene using the sedimentary noise model. Notably, the sea-level variations near the Oligocene-Miocene boundary exhibit a weak response to astronomical forcing. Further application of recurrence quantification analysis (RQA) reveals nonlinear characteristics in the region's climate evolution. By integrating sporopollen data, we classified the climate history into three distinct stages. Over long timescales, astronomical forcing is the primary driver of global climate change. However, local sedimentary and environmental variations introduce strong nonlinearities, leading to phase shifts in response to astronomical forcing. Finally, we propose a simplified model to elucidate the mechanisms by which Earth's orbital obliquity influences climate system dynamics, providing new insights into the climate evolution of the late Oligocene to early Miocene.</div></div>","PeriodicalId":19928,"journal":{"name":"Palaeogeography, Palaeoclimatology, Palaeoecology","volume":"673 ","pages":"Article 113007"},"PeriodicalIF":2.6,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lake Xiaolongchi, a small alpine lake located in Northern Tianshan Mountains of arid central Asia, is used to explore the source area of the main pollen taxa in lake sediments. Pollen data of a well-dated sediment core from Lake Xiaolognchi are analyzed to discuss vegetation dynamics on the sunny and shady slopes and their response to climate. The pollen data are used to reconstruct the temperature and humidity changes over the last 8000 years. <em>Picea</em> pollen mainly originates from the shaded slopes, while <em>Artemisia</em>, Amaranthaceae and Poaceae are mainly from the sunny slopes. Cyperaceae pollen originates primarily from the tundra vegetation in the high elevation of the catchment. Accordingly, the taiga biome score reflects changes in arboreal plants on the shady slopes of the catchment, which are sensitive to temperature. High or low taiga biome scores can be used to indicate high or low temperatures, respectively. The steppe and desert biome scores reflect steppe and desert vegetation on the sunny slopes, which are sensitive to humidity. High steppe/desert biome scores can be used to infer humid/arid climate respectively. The temperature reconstruction based on the taiga biome score exhibits a cooling trend, and the humidity reconstruction based on the steppe and desert biome scores shows a wetting trend over the past 8000 years. These trends are generally consistent with other climate records from the arid central Asia. The climate was extremely dry from 2.1 to 1.7 cal kyr BP, corresponding to the Roman Warm Period (RWP). This extremely dry event appears to be a regional signal and possibly have caused a significant decrease of archaeological sites in arid central Asia in that period.</div></div>","PeriodicalId":19928,"journal":{"name":"Palaeogeography, Palaeoclimatology, Palaeoecology","volume":"673 ","pages":"Article 113009"},"PeriodicalIF":2.6,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we document the changing proportion of acritarch morphotypes through two well-documented Darriwilian (Middle Ordovician) sections of Öland, Sweden. Progressive changes of key morphological characters, such as the standard process length, as well as the relative abundance of different morphotypes, are continuous throughout the sections. These changes in the acritarch assemblages parallel the transition from deeper to shallower water environments as deduced from local facies analyses and regional sedimentation patterns. Consequently, the previously suggested biostratigraphical signals in the acritarch assemblages could also be interpreted as ecophenotypical responses to the changing palaeoenvironment.

The sediments deposited in this lake are assigned to the Karewa Group. In this paper, we reconstruct palaeoclimate using the Climate Leaf Analysis Multivariate Program (CLAMP) and the Coexistence Approach (CA), based on late Pliocene leaf assemblages recovered from the Dubjan Member of the Hirpur Formation (Karewa Group). CLAMP-based climate reconstruction indicates a mean annual temperature (MAT) of 18.1 ± 2.3 °C and a cold month mean temperature (CMMT) of 11.1 ± 3.5 °C, suggesting a warm subtropical climate with a 9–10 month growing season. Estimated growing season precipitation (GSP) was 159.2 ± 64.3 cm, with a strong seasonal rainfall pattern (WET:DRY ratio of 6.9:1).

To further elucidate the driver of the productivity in the western Bay of Bengal we analysed various paleoproductivity proxies over 1.3 Myr at the International Ocean Discovery Program (IODP) Expedition 353 Site U1446 located near the Mahanadi Basin in the Northwest (NW) Bay of Bengal.

We found that δ¹³C_org, δ¹⁵N, and other Rock-Eval parameters, reflect the contributions of both marine and terrestrial Organic Matter (OM). However, a shift in OM from marine to terrestrial was observed across MPT. The increase in productivity after the MPT was most pronounced during the glacial periods and was closely linked to climate variability in the SH. The productivity in the interglacial periods was low owing to intensified monsoon associated with NH climate variability. Our results, therefore, infer that NH climate variability (during interglacials,) in tandem with SH climate variability (during glacials) modulates productivity in NW Bay of Bengal.
