This study provides a comprehensive and quantitative estimate of how global temperatures
have changed during the last 540 million years. It combines paleotemperature …

It is well established that greenhouse conditions prevailed during the Cretaceous Period (~
145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

The temporal link between large igneous province (LIP) eruptions and at least half of the
major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of …

The Cretaceous/Paleogene mass extinction, 66 Ma, included the demise of non-avian
dinosaurs. Intense debate has focused on the relative roles of Deccan volcanism and the …

A compilation of foraminiferal stable isotope measurements from southern high latitude
(SHL) deep-sea sites provides a novel perspective important for understanding Earth's …

Mass extinctions manifest in Earth's geologic record were turning points in biotic evolution.
We present 40Ar/39Ar data that establish synchrony between the Cretaceous-Paleogene …

The Cretaceous-Paleogene boundary~ 65.5 million years ago marks one of the three largest
mass extinctions in the past 500 million years. The extinction event coincided with a large …

The Chicxulub asteroid impact (Mexico) and the eruption of the massive Deccan volcanic
province (India) are two proposed causes of the end-Cretaceous mass extinction, which …

Paleobotanists have long used models based on leaf size and shape to reconstruct
paleoclimate. However, most models incorporate a single variable or use traits that are not …
