Terrestrial climate in mid-latitude East Asia from the latest Cretaceous to the earliest Paleogene: A multiproxy record from the Songliao Basin in northeastern China
From the latest Cretaceous (late Campanian to Maastrichtian,~ 75–66 Ma) to the earliest
Paleogene, fluctuations in greenhouse climate, inferred primarily from marine sediments …

Calibration of chron C29r: New high-precision geochronologic and paleomagnetic constraints from the Hell Creek region, Montana
The mass extinction at the Cretaceous-Paleogene boundary marks one of the most
important biotic turnover events in Earth history. Yet, despite decades of study, the causes of …

The late Mesozoic‐Cenozoic Arctic Ocean climate and sea ice history: A challenge for past and future scientific ocean drilling
Abstract Over the past 3–4 decades, coincident with global warming and atmospheric CO2
increase, Arctic sea ice has significantly decreased in its extent as well as in thickness …

[HTML][HTML] Combined cadmium and chromium isotopes record a collapse of bioproductivity across the Cretaceous—Paleogene boundary in the Danish basin
Cadmium (Cd) isotope signatures (δ 114 Cd) deduced from modern and ancient marine
deposits are often used as a proxy for bioproductivity and for micronutrient cycling, whereas …

Absolute seasonal temperature estimates from clumped isotopes in bivalve shells suggest warm and variable greenhouse climate
Seasonal variability in sea surface temperatures plays a fundamental role in climate
dynamics and species distribution. Seasonal bias can also severely compromise the …

Integrated bio-and carbon-isotope stratigraphy of the Upper Cretaceous Gurpi Formation (Iran): a new reference for the eastern Tethys and its implications for large …
A high-resolution stratigraphic analysis of the Upper Cretaceous Gurpi Formation has been
undertaken in the Shahneshin section (Zagros Basin, Iran). New results on calcareous …

Maastrichtian oil shale deposition on the southern Tethys margin, Egypt: Insights into greenhouse climate and paleoceanography
A comprehensive set of organic and inorganic geochemical proxies, clay mineralogy, and
molecular fossils are presented from two biostratigraphically well-dated oil shale horizons of …

[HTML][HTML] Multi-proxy record of the mid-Maastrichtian event in the European Chalk Sea: paleoceanographic implications
The Cretaceous provides us with an excellent case history of ocean-climate-biota system
perturbations. Such perturbations occurred several times during the Cretaceous, such as …

Robust multi-proxy data integration, using late Cretaceous paleotemperature records as a case study
In paleoclimate studies, multiple temperature records are often compared and combined to
evaluate temperature trends. Yet, no standardized approach for integrating proxy-derived …
