Summary: Our understanding of Late Cretaceous dinosaur ecosystems has improved through stable isotope analyses. An analysis of a Triceratops bonebed provides insights into the paleoecology of these large herbivores and their habitat use, diet, and possible migration.

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: Through heating experiments of MHC, the researchers found that the stable isotopic compositions of ikaite pseudomorphs can be used for paleoclimate reconstruction, providing information about water temperature, δ18O(CARB), δ18O(fluid), and δ13C(CARB) which are influenced by dehydration diagenetic effects.

Summary: The Cretaceous climate was characterized by arid and semiarid conditions around the world, with significant paleoclimatic reconstructions being developed in the Bauru Basin of Brazil due to the well-preserved sedimentary sequences and abundant fossil content. By studying the paleosols in the basin, researchers identified environmental and climatic patterns from the Lower to Upper Cretaceous, allowing for the elaboration of maps of paleoclimatic evolution that contribute to the understanding of Cretaceous paleoclimatic context in South America.

Summary: The study suggests that the paleoenvironment of central Myanmar did not significantly change from the late Miocene to early Pleistocene, serving as a refuge for forest/woodland dwellers. The development of drainage systems in late Neogene Myanmar likely buffered against the rain shadow effect of the IndoMyanmar Ranges. The current aridification in central Myanmar is likely related to Middle to Late Pleistocene sea-level changes in the SE Asian region.

Summary: This article presents a high-resolution lacustrine record from a western Mediterranean intramountain basin, providing detailed paleoclimatic information from the Late Miocene to the Early Pleistocene. The study reveals the influence of orbital forcing and global paleogeographic and climate change on regional paleoclimate, as well as the connection between continental climate and marine dynamics in southwestern Europe. It suggests that the closure of the Central Atlantic Seaway and changes in the Atlantic Meridional Overturning Circulation played a role in the regional climate variability.

Summary: Various geochemical analyses were conducted on Paleogene terrestrial mammal remains to determine their taphonomy, stratigraphic provenance, and paleoenvironmental conditions. The results suggest that the mammal fossils were initially deposited in a marine setting before being washed into the sea. By comparing ratios with background datasets, researchers were able to characterize the stratigraphic levels bearing the fossils.

Summary: This research presents the paleoenvironmental evolution of a drained lake at the Lousoi plateau (northern Peloponnese) for the past 10,000 years, based on the analysis of a 7 m depth core. The study reveals that the lake experienced increased water levels and wet climatic conditions from 10,900 to 7700 cal BP, with a dry pulse at 9400 cal BP. The transition to more shallow waters and a more oxygenated phase occurred at 8200 cal BP. In the Late Holocene period, the lake was highly affected by pedogenic processes, making it difficult to distinguish paleoclimatic/paleoenvironmental signals.

Summary: This study reconstructs the sedimentary mechanisms of shale in the southern Sichuan Basin by combining logging, mineralogy, and geochemistry. The study found that the shale in the area can be divided into different sequences, which are influenced by factors such as volcanic eruption and glaciation, leading to different sedimentary environments and lithofacies. This has significant implications for the development and exploration of shale gas.

Summary: After the K-Pg crisis, crocodyliforms underwent strong diversification on Gondwanan continents, with most being tethysuchian species, particularly with a significant increase in marine species. This suggests that crocodyliforms did not suffer from the crisis and benefited from the extinction of large marine reptiles to evolve in marine environments.

Summary: Spectral analysis is a time-series analysis technique that breaks signals down into linear combinations of harmonic components. It gained popularity in palaeoclimatology since the early 1980s due to the availability of long time series of past climates and the development of new methods. This paper reviews important spectral analysis methods for palaeoclimate time series, discussing their prerequisites, advantages, and disadvantages, while also providing an overview of suitable software and computer code.

Summary: The study focused on investigating the warm and humid paleoclimate dominated in the Yili Basin during the early-Early Jurassic and Middle Jurassic, which led to high productivity of peat-forming paleo-vegetation. In contrast, the late-Early Jurassic interval between these formations was marked by relatively arid conditions, interrupted peat formation, and preservation under hypoxic sedimentary conditions.

Summary: The research on the Eocene halite deposits in the Kohat Basin reveals the origin and evolution of these deposits, shedding light on the paleoclimate in Asia during the Eocene period. The halite samples showed a mixture of different solutions and the involvement of recrystallization in their formation, pointing to unstable paleoclimatic conditions that led to the transition from an evaporite basin to a terrestrial foreland basin. These events were controlled by regional tectonic activities and linked to the uplift of the NW Indian Craton and the Eocene thermal maximum.

Summary: Cattle populations arrived in Southern Africa almost 2000 years ago, brought by farming communities migrating southwards. Over the centuries, cattle have played a crucial role in livestock production, cultural events, and social status indicators. Research indicates that indigenous cattle breeds in South Africa are well-adapted to local environmental conditions and have the potential to enhance productivity and alleviate poverty in the developing livestock sector.

Summary: This study examines charcoal sequences from the Holocene period in southern Africa and compares them with paleoclimate records and archaeological data to analyze the relationship between human activity and fire. The findings suggest that increased fire activity during the late Holocene coincides with changes in human activity, particularly the introduction and intensification of food production. This indicates that humans used fire as a tool to manage landscapes in a novel way, with outcomes influenced by regional ecosystem characteristics.

Summary: AfriArch is a community that aims to integrate datasets related to human-environmental interactions in Holocene Africa. This dataset includes bioarchaeological stable isotope (C/N/O) and radiocarbon measurements from African archaeological sites, as well as modern measurements reported in original publications. The dataset can be used for various studies, such as paleodietary, paleodemography, paleoclimatic, and paleoenvironmental research, and can also help identify data gaps and shape future research agendas.

Summary: Despite advances in understanding the Paleolithic record, there is still much unknown about the evolutionary and ecological consequences of changes in human behavior. Developing expectations for identifying these phenomena is difficult due to the multi-generational impacts of behavior changes, requiring insights into emergent phenomena over longer time periods. Generative models show promise in exploring the unexpected consequences of human-environment interaction.
