Summary: The deposition of Mesozoic carbonates in the Horn of Africa is significant for correlation purposes. Based on the discovery of calcareous nannofossils and calpionellids, the presence of Cretaceous deposits in the Blue Nile Basin is confirmed, extending the age of the Antalo Limestone Formation to the late Berriasian. This discovery not only impacts the biostratigraphy of Ethiopia but also integrates the study region of eastern Africa with the South Tethysian margin calpionellid domain for the first time.

Summary: The surface sediments in the Tarim Basin originate from Central Asia and adjacent arid/semi-arid areas, being completely homogenized by the Westerlies and local wind systems before deposition. The sediments in most parts of the basin contain a higher proportion of dust from Central Asia in the 2-16μm fraction and exhibit a relatively high level of homogeneity. Additionally, materials derived from regional sources dominate the 32-63μm and >63μm fractions, with fluvial systems playing an important role as additional transport mechanisms.

Summary: The Angeac-Charente site in France has yielded a diverse array of fossils from the Lower Cretaceous period, including vertebrate macroremains, microremains, and coprolites. This site provides a snapshot of a Lower Cretaceous ecosystem and is considered a fossil-Lagerstatte due to the richness, diversity, and preservation of its fossils. The bonebed at Angeac-Charente is complex, likely formed by a combination of ecological, biological, and physical processes such as predation, mass mortality events, and hydraulic transport.

Summary: Extant terrestrial vertebrates, including birds, have symbiotic relationships with insects and arachnids, but arthropod-vertebrate symbioses in the fossil record are rarely found. In this study, direct and indirect evidence of beetles feeding on feather remains from an undetermined theropod host 105 million years ago is presented. An exceptional amber assemblage was found, including beetle larval exuviae associated with feathers, along with additional amber pieces containing isolated larval exuviae. The morphological and taphonomic data suggest that these beetle larval exuviae belonged to a keratophagous species, indicating a symbiotic relationship between beetles and their Early Cretaceous relatives similar to current ecosystems.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

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.
