Summary: Through stratigraphy, chemostratigraphy, and molecular compound analyses of the Kuqa River section in the Tarim Basin, north-western China, we uncover the evolutionary processes of wildfires in the Early Jurassic. Our findings suggest that wildfires are influenced by both paleoclimate change and astronomical factors, with periodically enhanced wildfires corresponding to high eccentricity cycles. These results are important for understanding the impact of wildfires on Earth systems and the interactions between the atmosphere and biosphere.

Summary: The study presents evidence of orbital-scale variability of the East Asian summer monsoon in the early Miocene period, with dominant cyclical patterns of approximately 100 kyr eccentricity. This variability is linked to Antarctic ice sheet modulations and changes in weathering intensity in the Lanzhou Basin, possibly influenced by changes in westerly moisture due to orogenic barriers and uplift of NE Tibet during the late Oligocene-early Miocene period.

Summary: Understanding the evolution of the East Asian Summer Monsoon (EASM) at different time scales is important for revealing the interactions between the hydrosphere, land, oceans, and atmosphere. By studying the late Miocene period, researchers have reconstructed the EASM precipitation and found that it is influenced by global climate and the uplift of the Tibetan Plateau. Additionally, on orbital time scales, the eccentricity periodicity plays a dominant role in the EASM precipitation cycles.

Summary: This study used time series analysis to investigate the sedimentary processes of an Upper Jurassic (Tithonian) section from the Adriatic Platform and found that the sedimentation was influenced by both random factors and Milankovitch cycles. The analysis of synthetic data sets and the Tithonian data revealed significant differences between random and astronomically-forced sedimentation. Spectral analysis and wavelet analysis showed that the thickness of the Tithonian parasequences was influenced by long-term and short-term eccentricity as well as obliquity and obliquity modulation.

Summary: The sedimentological record of the Pranjani Basin in Serbia reveals tectonic and climatic variations in the Dinaridic orogen. The Mg-clay-bearing succession in the lacustrine strata demonstrates cyclical patterns driven by water availability, reflecting wet and dry intervals under semi-arid to arid climatic conditions. Longer-term fluctuations in lake level and chemistry are attributed to alternating humid and arid phases influenced by tectonic uplift and subsidence in the region.

Summary: The study discusses the evolutionary history, diversity, and distribution of Cainozoic to present-day species of the Trochidae subfamilies Cantharidinae and Trochinae based on an extensive literature survey. The European fossil record suggests two major radiations during the Eocene and Miocene periods, with the present-day fauna originating in the Pleistocene and Holocene. There is no clear correlation between the evolution and diversity of these subfamilies with major geodynamic events, except for a notable radiation of Cantharidinae following the hydrological isolation of the Paratethys Sea in the late Miocene.

Summary: Tuffaceous layers in Miocene sediments of the Dinarides and Eastern Alps were analyzed to determine their mineralogical composition and infer potential source areas of volcanic ash. The tuffs examined displayed varying degrees of alteration, with different compositions ranging from andesite to rhyolite. Using trace-element correlation, it was determined that the earlier tuffs likely originated from the Western Carpathians, while the later ones were sourced from the Apuseni Mountains and/or Eastern Carpathians. The spatial distribution of the tuffs suggests tropospheric easterly trade winds as the likely carrier of ash towards the southwest.

Summary: This study presents a revision of Clavatulidae gastropods from the Neogene of the Central and Eastern Paratethys seas. A total of 83 species and 17 genus-level groups were documented after revision. The presence of certain Clavatulidae genera in the Paratethys Sea suggests a biogeographic relationship with extant Clavatulidae faunas from the tropical eastern Atlantic. The high biodiversity and endemicity observed in Paratethyan assemblages indicate that the Central Paratethys was a major center of radiation for clavatulid gastropods. Clavatulidae diversity was found to be low in the Eastern Paratethys, restricted to the early Miocene Sakaraulian.

Summary: This study presents the first detailed intra-basin correlation of Upper Miocene deposits in the Austrian part of the Vienna Basin, integrating the most important hydrocarbon fields. It uses a high resolution dataset to calculate regional differences in sedimentation rates over a time span of approximately 1.6 million years. The study reveals high lateral variability in thicknesses during the early Pannonian, which gradually decreases. The shift of high subsidence rates from the southern to the northern Vienna Basin during the middle Pannonian is documented. The still high sedimentation rates during the late Pannonian indicate persisting extensional tectonics in the Vienna Basin throughout the Late Miocene.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
