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 …

Temporal correlation between some continental flood basalt eruptions and mass extinctions
has been proposed to indicate causality, with eruptive volatile release driving environmental …

Cyclostratigraphy is an important tool for understanding astronomical climate forcing and
reading geological time in sedimentary sequences, provided that an imprint of insolation …

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 …

This paper addresses two fundamental issues in cyclostratigraphy and paleoclimatology:
identification of astronomical forcing in sequences of stratigraphic cycles, and accurate …

Calcareous nannofossils have provided a powerful biostratigraphic tool since the 1950's
and 1960's, when several milestone papers began to highlight their potential use in dating …

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 …

We present here a new solution for the astronomical computation of the orbital motion of the
Earth spanning from 0 to− 250 Myr. The main improvement with respect to our previous …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

Astronomical calculations reveal the Solar System's dynamical evolution, including its
chaoticity, and represent the backbone of cyclostratigraphy and astrochronology. An …
