Short summary
StratoBayes is a novel Bayesian method for aligning stratigraphic data from multiple sites. It integrates diverse information, such as geochemical signals and radiometric dates, and provides robust age estimates with quantified uncertainty for all sites. We use StratoBayes to correlate lower Cambrian δ13C records from Morocco with an undated record from Siberia, and estimate the age of the world’s oldest trilobites.

To understand human impact on climate and biodiversity, we studied fossil teeth of Gomphotherium from Miocene Portugal. Chemical patterns, like those in modern elephants, show seasonal diet changes and geophagy during dry periods. This suggests dry seasons shaped animal behavior and ecosystems, offering insights into how land life responded to past warming—and how it might react to future climate change.

Short summary
To test the tolerance of past shallow marine ecosystems to extreme climates, we collected and compiled stable and clumped isotope data from rudist bivalves that lived in tropical shallow marine waters in present-day Oman during the Campanian (75 million years ago). Our dataset shows that these animals were able to withstand exceptionally warm temperatures, exceeding 40 °C, during hot summers. Our finding highlights how seasonal climate extremes impact marine biodiversity.

Around 70 million years ago, during the Late Cretaceous, Earth’s climate was undergoing long-term cooling despite high CO₂ levels. Using an advanced temperature reconstruction technique, we analyzed foraminifer fossils from the European Chalk Sea. Our results show highly variable surface waters, likely influenced by freshwater inputs or upwelling, while deeper waters remained warm and stable, possibly influenced by shifting ocean currents. This improves our understanding of past ocean dynamics.

Anticosti Island has a well-preserved rock succession throughout the Aeronian–Telychian boundary in the Llandovery Epoch, Silurian period, which includes two important biogeochemical events, the late Aeronian and the Valgu. This study suggests the position of this boundary in Anticosti based on the correlation of the island’s chitinozoan assemblages with the global occurrences, confirming both a remarkable preservation of upper Aeronian rocks and the record of the Valgu event.

Short summary
Middle–Late Devonian sedimentary rocks are often punctuated by anoxic black shales. Due to their semi-regular nature, anoxic events may be linked to periodic changes in the Earth’s climate caused by astronomical forcing. We use portable X-ray fluorescence elemental records, measured on marine sediments from Germany, to construct an astrochronological framework for the Kellwasser ocean anoxic Crisis. Results suggest that the Upper Kellwasser event was preceded by a specific orbital configuration.

Stable oxygen and carbon isotope analyses of fossil bivalves, gastropods and fish ear bones (otoliths) is frequently used for seasonality reconstructions of past climates. We measured stable isotope compositions in multiple specimens of two bivalve species, a gastropod species, and two species of otoliths, from two early Eocene (49.2 million year old) shell layers. Our study demonstrates considerable variability between different taxa, which has implications for seasonality reconstructions.

The datasets presented are the density, water isotopes, ions, and conductivity measurements, as well as age models and surface mass balance (SMB) from the top 120 m of two ice cores drilled on adjacent ice rises in Dronning Maud Land, dating from the late 18th century. They offer many development possibilities for the interpretation of paleo-profiles and for addressing the mechanisms behind the spatial and temporal variability of SMB and proxies observed at the regional scale in East Antarctica.

Fossil bivalves are an excellent climate archive due to their rapidly forming growth increments and long lifespan. Here, we show that the extinct bivalve species Angulus benedeni benedeni can be used to reconstruct past temperatures using oxygen and clumped isotopes. This species has the potential to provide seasonally resolved temperature data for the Pliocene to Oligocene sediments of the North Sea basin. In turn, these past climates can improve our understanding of future climate change.

The Leeuwin Current transports warm water along the western coast of Australia: from the tropics to the Southern Hemisphere midlatitudes. Therewith, the current influences climate in two ways: first, as a moisture source for precipitation in southwestern Australia; second, as a vehicle for Equator-to-pole heat transport. In this study, we study sediment cores along the Leeuwin Current pathway to understand its ocean–climate interactions between 4 and 2 Ma.

Short summary
We used new geochemical measurements to study the expression of astronomical climate cycles recorded in the Ordovician (~ 460 million years ago) geological sections of the Crozon Peninsula (France). This type of geological archive is not often studied in this way, but as they become more important going back in time, a better understanding of their potential astronomical cycles is crucial to advance our knowledge of deep-time climate dynamics and to construct high-resolution timescales.
