Summary: In hot environments, collagen degrades quickly, making it difficult to obtain accurate dates through C-14 dating of bones. Although hydroxyapatite contains a small amount of carbonate, it is often heavily contaminated with exogenous carbonate, leading to underestimated dates. Acetic acid appears to be the most effective in removing carbonate contaminants.

Summary: Isotope analyses are common in analyzing ancient bones for diet and chronology interpretation. Evaluating collagen yield is important for selecting adequate specimens, and this study used proteomic methods to investigate proteinaceous biomolecules in poorly preserved samples. While waste fractions contain significant proteins, their abundance does not correlate with collagen yield, suggesting they can still provide useful molecular information.

Summary: The carbon and nitrogen isotopic compositions of bone and tooth collagen are important for studying past biological, environmental, and cultural phenomena. Collagen provides reliable quality control criteria for isotopic data, with traditional C:N QC parameters sometimes leading to unreliable isotopic compositions due to contamination. New collagen QC criteria specific to certain taxa and environments have been proposed based on a model's results, aiming to improve the interpretation of isotopic data by accurately identifying contaminated samples.

Summary: Diagenesis alters the trace elements biogenic signatures in fossil tooth enamel and bone. Leaching can restore the additive-like diagenesis in enamel but is ineffective for the substitutive-like diagenesis, while bone shows a consistent offset toward 44Ca-enriched values. Ca isotopes in fossil enamel are relatively immune to extensive diagenesis due to the low porosity.

Summary: The study analyzed the microstructure and composition of enamel in fossil and extant proboscidean teeth to assess diagenetic alterations, finding that there were no or only negligible modifications in the fossils collected and that these minor alterations were not age-dependent. This indicates that diagenesis has not significantly affected the samples studied and they are suitable for chemical and paleontological studies and as proxies for reconstructing paleoclimate and paleoenvironment.

Summary: The existence of thermomineral waters in the Lisbon region has been known for centuries. This study investigated the characteristics and conceptual model of these waters through chemical analyses, environmental isotopes, and geochemical modeling. The results suggest that the physicochemical composition of thermomineral waters is mainly controlled by water-rock interaction processes and mixing of different water sources.

Summary: The Late Miocene in the Shuitangba area exhibited a wetter climate with stronger precipitation seasonality and an average temperature 3 to 4 degrees Celsius higher than today. Comparisons with the Siwalik region suggest earlier spread of C-4 biomass and more pronounced transition to a drier habitat in the Siwalik region relative to Yunnan, possibly linked to the unique growth history of the Himalayan-Tibetan Plateau.

Summary: The megalithic cultures in central India serve as important connections between the southern Neolithic-Chalcolithic cultures and the early historical period, providing insights into the ancient traditions and knowledge of early inhabitants. Through the analysis of equine tooth-enamel and organic food remains recovered from pots in megalithic burials, the past-diet and hydro-climatic conditions of the Vidarbha region have been deduced. The scientific dating of these burial sites, however, remains challenging due to the scarcity of dateable material.

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.
