Fossils provide invaluable data for evolutionary studies in oceanic islands. The paleontological record of the Macaronesian archipelagos has been the target of many researchers for a long time, with a recent surge in interest in scientific research related to their paleontological heritage. In the Macaronesian Azores archipelago, the marine invertebrate fossil record from the warmest period of the Last Interglacial stage (also known as Marine Isotopic Stage 5e—MIS 5e) represents approximately 95.6% of the total species. In contrast, the MIS 5e marine vertebrate fossil record comprises only four reported species (2.2%), with marine algae accounting for the remaining 2.2% (four species). This study reports on—and adds to the paleobiodiversity of the MIS 5e deposits at Santa Maria Island (Azores Archipelago)—two marine mesopelagic lanternfishes, identified from their otoliths: Diaphus cf. holti Tåning, 1918, and Symbolophorus veranyi (Moreau, 1888). Finally, we offer a plausible explanation for the presence of mesopelagic fishes in the MIS 5e fossiliferous deposits of Santa Maria Island. Full article

Arid Central Asia (ACA) is a major source of atmospheric dust in the Northern Hemisphere; however, the evolutionary models and driving mechanisms of Holocene aeolian activity in this region remain debated. Based on 13 reliable AMS ¹⁴C dates from the Sayram Lake SLM2009 sediment core, this study reconstructs the Holocene sequence in aeolian activity through end-member modeling analysis (EMMA). It evaluates its relationship with regional atmospheric circulation. Four end-members were identified from base to top: EM1, with a modal grain size of 7.58 μm, represents low-energy suspension deposition; EM2 (26.30 μm) reflects lacustrine hydrodynamic processes; while EM3 (52.48 μm) and EM4 (416.86 μm) serve as proxies for regional aeolian activity. The results indicate that aeolian activity was relatively strong during the early Holocene (reaching peaks at 11.7–11.2 and 9.2–8.1 cal ka BP), significantly intensified during the mid-Holocene (7.3–5.3 cal ka BP), and gradually weakened in the late Holocene (since 4.0 cal ka BP). Comparison of the aeolian record from Lake Sayram with Greenland ice cores, North Atlantic ice-rafted debris events, and the GISP2 K⁺ record indicates that variations in aeolian activity in arid Central Asia are closely linked to the Northern Hemisphere climate system. We propose that these variations were primarily modulated by large-scale atmospheric circulation, driven by the synergistic interaction between the Siberian High and the mid-latitude westerlies.

The main objective of the present study is to reveal the palette of pigments and the other specific constituent materials as well as the techniques used by the Roman artists to create the mural paintings discovered in the ancient city of Tomis, the modern-day Constanţa, Romania’s largest seaport and a major tourist hub on the Black Sea. This paper is an archeometric study based on the physical, chemical and biological analyses of the archeological Roman mural painting fragments from the ancient city of Tomis dating from the 5th to 6th century A.D. and to our knowledge is among the very few research studies carried out so far on the ancient Roman wall painting discovered in Romania. The methods of scientific investigation employed directly on the archeological fragments, on samples taken from the fragments and on the cross-sections prepared from the samples were: optical microscopy (OM), digital microscopy, X-ray fluorescence spectrometry (XRF) and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR). Examination and analysis of the archeological mural fragments revealed that the painted fragments consist of ground support and successive layers of color displaying specific characteristics of the artistic technique, such as imitation of marble cladding or meticulous smoothing of the surface to achieve a glossy and compact finish. It was also found that fragments exhibit subtle variations in different colors, identified in general terms, showing seven color tones: cinnabar red, red-violet, red ochre, yellow ochre, white, gray-blue, gray-black and black. The physical–chemical and biological analyses carried out provide the diagnosis and theoretical basis for choosing an appropriate conservation methodology and the correct restoration treatment of the discovered mural painting, with a view to its museum display through exhibition and virtual reconstruction and scientific use by the setting up of a useful database for researchers or specialists in museums on Roman archeology and art.

Modern pollen rain studies provide essential calibration for interpreting fossil pollen records, particularly in montane environments. This study explores pollen–vegetation relationships along an altitudinal transect in the Rarău Massif (Eastern Carpathians, Romania). Eight moss cushion samples collected between 1215 and 1619 m a.s.l. were analysed palynologically and compared with eight paired vegetation surveys. Multivariate analyses, including hierarchical clustering, Mantel tests, NMDS, and Procrustes analysis, were applied to evaluate floristic and palynological similarity in relation to altitude. Pollen spectra are dominated by Picea, reflecting the prevalence of spruce forests characteristic of the montane belt, while Abies and Pinus occur in lower proportions, indicating a secondary role. Broad-leaved taxa such as Fagus, Betula, and Alnus complement the arboreal pollen signal, whereas thermophilous taxa Quercus and Tilia represent extra-local pollen input from lower altitudes. Herbaceous and shrub taxa are generally underrepresented in the pollen record relative to field observations. Pollen taxa associated with anthropogenic disturbance (Plantago, Rumex, Artemisia and Urtica) show a constant presence, which may suggest localized human influence likely linked to grazing and tourism. Statistical results show weak and non-significant correlations between pollen composition, vegetation structure, and altitude. Overall, modern pollen rain reflects the dominant vegetation structure of the studied montane belt but shows limited fidelity at the local floristic scale. Full article

Alluvial plains in the marginal zone of the monsoon system are sensitive to the climate–hydrology interaction. However, long term, high-resolution sedimentary records remain scarce in the Songnen Plain of Northeast China. This limited our understanding of the paleoclimate–paleohydrology coupling evolution over glacial–interglacial cycles. A 50.6 m continuous core was retrieved from the western Songnen Plain. The age–depth model and wavelet transform spectrum showed sedimentary continuity from ~885 ka B.P. (the late Early Pleistocene) to ~6 ka B.P. (the early Holocene), with no major hiatuses exceeding orbital resolution. Grain size analyses revealed 18 microfacies, which were synthesized into two major evolutionary cycles: a fan-delta front cycle (dominated by subaqueous mouth bars and distributary channels) and a fan-delta plain cycle (characterized by intertributary bays, floodplain lakes/swamps, and crevasse splays). The absence of pro-delta facies and the sediment succession record the oscillatory shrinkage of the Songnen paleolake. The pulsed enhancements of hydrodynamic energy, marked by grain size coarsening, coincide with major glacial–interglacial transitions (MIS 20/19, 18/17, 16/15, 14/13, 8/7, 6/5, 4/3, and 2/1), whereas fining grain sizes dominate warm interglacial periods (MIS 11, 9, 7, 5, 3, 1). These patterns are sensitive response of the alluvial plain to orbital-scale climate change. Cold–arid glacial background promoted vegetation loss and hydrological instability, and warm–humid interglacial background favored low-energy hydrological condition. This study demonstrates that the regional alluvial evolution was primarily controlled by global ice-volume fluctuations through variability of the East Asian summer monsoon. This study provides a reference for the muti-scale climate–hydrology coupling mechanism study in the northern marginal zone of EASM and highlights the importance of alluvial sediment succession in paleo-research.

Dental wear provides valuable evidence for reconstructing past human behaviour, including diet abrasiveness and non-masticatory activities such as the use of teeth as a “third hand”. This study investigates activity-induced dental modifications (AIDMs) in two adult human skeletons recovered from a 15th–19th-century necropolis at the St. Athanasius Church in Niculițel (Tulcea County, Romania). Dental remains and associated dental calculus were examined using low- and high-magnification optical microscopy and scanning electron microscopy (SEM). Well-polished grooves with parallel striations were identified on the incisor crowns, consistent with repetitive extra-masticatory activities related to fibre drafting during spinning and textile production. Dental calculus analysis revealed the presence of plant and animal fibres, providing direct micro-contextual evidence for textile-related practices. These results offer new insights into the use of teeth as tools and contribute to the reconstruction of textile-related craft activities during the Ottoman and early modern periods in southeastern Europe.

Shell middens of Guyana’s northwestern coast are a tangible stratified archive of prehistoric occupation and land use during the Holocene, an era of increased human impacts on the landscape. This study integrates stable isotope and zooarchaeological evidence to understand prehistoric land use, shell midden function, and the complex relationship between archaic populations and their landscape. We synthesize recently excavated data and archival museum collection for seven sites dating between 7500 and 2000 BP including stable isotope results of 37 individuals. Zooarchaeological materials are pooled to provide long-term patterns of human predation during the Holocene while reducing site-specific noise. This we believe highlights patterns of prey selection and exploitation intensity. We conclude that climate fluctuations during the mid Holocene influenced fishing intensification and subsequently a shift in human predation, which affected small to medium-sized fauna, estuary productivity and changes in vegetation patterns including mangrove expansion. These changes were shaped by landscape manipulation and influenced by shoreline movement and population mobility and seasonal resource use. Altogether, these processes left enduring ecological legacies along the northwestern coast of Guyana. Full article

This study presents new phytolith data that reconstruct the vegetation patterns and environmental context of medieval sites in northeastern Romania, integrated with previously published archaeozoological evidence. Sediment samples from cultural layers at Târgu Neamț–La Damian and Neamț Fortress were analysed following standard extraction protocols and classified according to the International Code for Phytolith Nomenclature (ICPN 2.0). The newly obtained phytolith assemblages are dominated by morphotypes from the Poaceae family, with diagnostic cereal forms, indicating intensive cereal use. The presence of arboreal and non-grass phytoliths further suggests a mosaic landscape combining grass-dominated open areas, pastures, and nearby woodland. When compared with existing faunal data, characterized by a predominance of domestic species such as cattle, sheep/goat, and pig, the results support the reconstruction of a diversified agro-pastoral economy adapted to local geomorphological and climatic conditions. The integration of new phytolith and existing archaeozoological data highlights the complementary role of plant microremains in reconstructing medieval environments, providing valuable insight into agro-pastoral resources, vegetation dynamics, and human–landscape interactions in the eastern Carpathian region. This approach enhances our understanding of the ecological basis of medieval Moldavian communities and contributes to the reconstruction of Late Holocene anthropogenic landscape dynamics within a Quaternary environmental framework.

Alluvial–proluvial parent-material soils are widely distributed in the Qinghai Lake Basin; however, their timing of development and associated climatic background remain poorly constrained. In this study, two representative alluvial–proluvial fan-covered soil profiles (QRZQ and YXC) from the Qinghai Lake Basin were investigated. Quartz optically stimulated luminescence (OSL) dating was combined with analyses of grain-size composition and soil organic carbon (SOC) to constrain the timing of soil development and its climatic background. The results show that the studied soil profiles are mainly characterized by Ah–As–C and Ah–A–C horizon configurations, with soil development spanning from 15.7 to 1.0 ka. The underlying alluvial–proluvial parent material of the QRZQ profile formed during the Last deglaciation, whereas the oldest OSL ages in the YXC profile occur within a weakly developed A horizon, indicating that this profile had already transitioned from a depositional environment to a pedogenic environment during the Last deglaciation. This contrast reflects staged differences between depositional and pedogenic processes within alluvial–proluvial settings. The soils were formed through upbuilding pedogenesis, in which sediment accumulation and top-down pedogenic modification proceeded concurrently. Grain-size composition and SOC characteristics further indicate that the depositional environment of the YXC profile was relatively stable. Integrating the obtained chronological results with regional climatic changes suggests that climate variability in the Qinghai Lake Basin exerted a primary control on the transformation between sedimentary processes and soil development. In particular, the Late Holocene (0–4 ka), characterized by a generally cold–dry climate accompanied by pronounced humidity fluctuations, represents an important pedogenic stage for alluvial–proluvial parent-material soils in the Qinghai Lake Basin. This study provides a robust chronological framework for further investigating the mechanisms of soil development in alluvial–proluvial environments from a climatic perspective. Full article

Compound geological disaster chains pose major challenges for disaster prevention in mountainous regions due to their complex mechanisms and cascading impacts. This study investigates a landslide–debris flow–flash flood hazard chain that occurred on 21 July 2024 in the Xujia River catchment, Mianning County, Sichuan Province, China. This event is used as a representative case to improve the understanding of the formation and amplification mechanisms of breach-type debris flows through dynamic inversion constrained by sedimentary records. The objective is to reconstruct the evolution of the event and assess its downstream hazard extent. Post-disaster sedimentary and geomorphological records, including deposit distribution, channel aggradation, and flow traces, were systematically analyzed based on remote sensing interpretation, unmanned aerial vehicle surveys, and detailed field investigations. These sedimentary data were used as key constraints to estimate debris flow magnitude and mobility under different rainfall scenarios. A rainfall flood scenario-based estimation method was applied to quantify debris flow magnitude, and numerical simulations were conducted using the Rapid Mass Movement Simulation model to reproduce debris flow propagation and deposition processes. The results indicate that prolonged antecedent rainfall triggered slope failure in a tributary, leading to the accumulation of landslide-derived material and the formation of a temporary channel blockage. The subsequent breach of this blockage significantly amplified debris flow discharge, velocity, and sediment outflow, resulting in downstream hazard expansion. Simulation results constrained by sedimentary evidence show that peak discharge and solid material output under breach conditions were approximately three times higher than those of rainfall-driven scenarios under comparable rainfall frequencies. These findings demonstrate that sedimentary records provide critical constraints for the inversion of landslide debris flow disaster chain dynamics and highlight the effectiveness of post-disaster evidence based numerical assessment for hazard analysis and risk mitigation in debris flow-prone mountainous catchments.

A group of avian species, mostly small passerines, allows us to reconstruct the landscape and general climate of an area of Fuerteventura prior to the arrival of the first humans. Many of the bird species are typical of forest environments and the edges of bodies of water, conditions incompatible with the current hot and arid climate. The record of a high number of quail as well as small flying passerines surely implies the concurrence of two types of diurnal birds of prey, hunters on the ground and in flight, respectively. No trace of the abundant Puffinus holeae has been found, which evidently occupied a habitat very different from those in the north and interior of the island. Full article

Lake Faro (Cape Peloro coastal lagoon, NE Sicily, Italy) is a distinctive Mediterranean coastal lake characterized by the coexistence of a shallow platform and a steep-sided deep basin within a very limited area. This study provides a sedimentological and geological characterization of the present-day lake floor based on grain-size, petrographic, statistical, and GIS-based analyses, with the aim of clarifying the relationship between basin morphology and modern depositional processes. The lake floor is subdivided into two main bathymetric domains. The shallow platform (<10 m water depth) is dominated by modern coarse-grained, very poorly sorted sediments, including gravel and very coarse- to medium-grained sand, deposited under high-energy, low-confinement conditions comparable to beach and open-lagoon environments. In contrast, the deep basin (>10 m water depth) is characterized by modern finer, organic-rich sediments with extremely poor sorting, reflecting lower-energy and more confined depositional conditions. A key new finding is the identification of upper Holocene beachrocks beneath the modern unconsolidated sediments of the shallow platform, which likely exert a significant morpho-structural control on platform development. Overall, the results highlight the strong influence of bathymetry on sediment distribution in coastal lake systems and provide a reference framework for comparable Mediterranean lagoon environments.

Phytoliths, pollen, and spores in a stratigraphic sequence from the Shishan Wetland (Azraq Basin, Jordan) and supported by modern pollen and phytolith data provide information on vegetation, climatic trends, and the influence of fire through MIS 2 and MIS 1. Additionally, a pilot study introduces an innovative approach that uses shape and morphometric parameters of Bulliform phytoliths to assess hydro-climatic changes. The phytolith terrestrial–aquatic ratio, grass–pollen size, and the Artemisia–Amaranthaceae ratio (A:C) indicate that during the Last Glacial Maximum (LGM), the study area was a wetland surrounded by steppe, and that during the deglaciation period (c. 20–11 ka), the wetland vegetation remained almost unchanged but the surrounding area tended to aridity. The phytoliths’ terrestrial ratio, the presence of C₄ grass phytoliths, and the low A:C is characterized by a reduced wetland and the establishment of a hot desert, like the present. The record at Shishan Marsh shows effective moisture trends concurrent with other records in the western southern Levant, but climatic events (Heinrich Stadial 1 and Younger Dryas) are not recorded because of the low time-resolution of the studied sequence. This study shows that combining pollen and phytoliths strengthens vegetation reconstruction by discerning local from regional floristic components and that Bulliform phytoliths are a potential tool to reconstruct hydro-climatic conditions.

This paper presents archeological data and chronometric dates documenting human presence in Serbia, central Balkans, during MIS 2. We describe findings from excavations at three cave sites and dating results from two additional localities. The evidence suggests that people were present in the area during the second half of the glacial peak between 25 and 19ka calBp. The chronological placement of these sites is complementary to what is known from adjoining regions, indicating that people may have occupied this part of the Balkans when they were not present elsewhere. All three excavated sites appear to represent short-term occupations, with relatively narrow ranges of activities, raising the question of whether they are fully representative of the land use system of foragers during MIS 2.

This work presents the results of an integrated monitoring of soil radon gas and seismic activity at Mt. Etna from August 2023 to May 2025, aimed at enhancing comprehension of magma migration and eruption dynamics. Radon data were collected using a permanent station with an alpha particle probe, aggregated hourly. The INGV-OE network monitored seismic activity at 100 Hz; volcanic tremor was analyzed using Root-Mean-Square (RMS) values from the Serra La Nave station. Earthquakes were located using the Hypoellipse algorithm and a 1D crustal velocity model. A robust correlation was found between radon and RMS anomalies, with the former preceding the latter with increasing probability over time (e.g., 30.1% within 1 day, 46.4% within 3 days). Correlations were also found between radon anomalies and Strombolian activity at the summit craters (e.g., 23.8% within 1 day for the Central Crater), suggesting a potential predictive role for radon. Conversely, correlations with paroxysmal events were weaker in the short term but increased over longer time windows. No clear correlation was found between radon anomalies and seismic strain release, likely due to differing temporal resolutions. These results support the idea that radon plays a role as a short-term precursor in volcanic unrest. Full article

The discovery of hippopotamid remain from a cave near the village of Grebci, Bosnia and Herzegovina, represents the first confirmed record of Hippopotamus in this part of southeastern Europe. The specimen, a partially preserved right os coxae, is housed at the Dubrovnik Natural History Museum. Morphological and metric analyses identify it as Hippopotamus cf. amphibius, although its fragmentary state prevents a more precise taxonomic attribution, while lack of stratigraphic context prevents chronological assessment. Despite the uncertain stratigraphic context, taphonomic analysis reveals evidence of mineralization, surface abrasion, and post-depositional fracturing, consistent with long-term cave deposition. This find fills a long-standing paleogeographic gap in the distribution of the Pleistocene hippopotamids in southeastern Europe, as no remains have previously been documented from the region outside Greece. Its presence supports the hypothesis that the Balkan Peninsula functioned as a migratory corridor for hippopotamids dispersing from Africa into Europe. Further research integrating stratigraphic, geochronological, and comparative morphological data is needed to clarify its evolutionary and biogeographic significance. Full article

This study presents a zooarchaeological and taphonomic analysis of the previously unstudied component of the Mousterian faunal assemblage from Unit A9 at Grotta di Fumane (northeastern Italy), offering refined insights into Neanderthal subsistence behaviour during Marine Isotope Stage 3. Building on the previously published analysis of the principal portion of the assemblage, the new data reaffirm a subsistence strategy focused on selective transport and intensive on-site processing of high-utility carcass components. The ungulate assemblage—dominated by Cervus elaphus and Capreolus capreolus, with additional contributions from Rupicapra rupicapra and Capra ibex—is characterised by the dominance of hindlimb elements, moderate cranial representation, and a pronounced scarcity of axial remains. These patterns indicate that carcass reduction commenced at kill sites, where low-yield trunk segments were removed, while high-nutritional-value limb portions were preferentially transported to the cave for secondary processing. Taphonomic indicators, including abundant cut marks, percussion notches, and extensive bone fragmentation, demonstrate systematic defleshing, marrow extraction, and possible grease rendering within the cave, activities that were spatially associated with combustion features. Occasional cranial transport suggests targeted acquisition of high-fat tissues such as brains and tongue, behaviour consistent with cold-climate optimisation strategies documented in both ethnographic and experimental contexts. Collectively, the evidence indicates that Unit A9 served as a residential locus embedded within a logistically organised mobility system, where carcass processing, resource exploitation, and lithic activities were closely integrated. These findings reinforce the broader picture of late Neanderthals as adaptable and behaviourally sophisticated foragers capable of strategic planning and efficient exploitation of ungulate prey within the dynamic environments of northern Italy.

By its availability and deposition dust is a key indicator for past climate variability. Due to the location in the main North African dust corridor, the Canary Islands preserve dust deposits in different geoarchives—for instance in valleys dammed by Quaternary volcanism. These basins act as sediment traps for aeolian, volcanic, and slope-derived material, forming alternating pale, carbonate-enriched (PCLs) and reddish, clay-enriched layers (RCLs). However, the extent to which these sequences retain primary dust signals remains uncertain. We examine the interpretability of locally called vega sediments by disentangling input pathways, post-depositional processes, and geomorphological controls. Two sections on Lanzarote (Teguise, Femés) and the section Vallebrón (Fuerteventura) were investigated using grain-size analysis, XRF and XRD measurements, and IRSL dating. The sequences reveal two dust components: high-intensity dust fall events forming PCLs, and persistent finer dust input preserved in RCLs through kaolinite. Many PCLs originated as loess-like deposits subsequently modified by carbonate redistribution, while clay mineral transformations complicate provenance interpretation. Archive clarity varies with geomorphology, from less distinctly layered, patchy carbonate-enriched succession at Vallebrón to continuous cyclic sequences in Teguise. Overall, these basins preserve both episodic dust events and continuous fine-grained input, offering a valuable framework for reconstructing Late Quaternary dust dynamics. Full article
