Astronomical insolation forcing is well established as the underlying metronome of
Quaternary ice ages and Cenozoic climate changes. Yet its effects on earlier eras …

Abstract Episodes of Environmental Change (EECs) were times of accelerated hydrological
cycle that punctuated the Early Cretaceous. Uncertainties in the geologic time scales …

Earth's climate system is complex and inherently nonlinear, which can induce some
extraneous cycles in paleoclimatic proxies at orbital time scales. The paleoenvironmental …

An accurate chronostratigraphy of the timing and magnitude of global sea-level trends and
their short-term variations is an indispensable tool in high-resolution correlations …

Global perturbations to the Early Jurassic environment (∼ 201 to∼ 174 Ma), notably during
the Triassic–Jurassic transition and Toarcian Oceanic Anoxic Event, are well studied and …

The linkages between the astronomical forcing of sea-level oscillations, the environment,
and climate change during the Late Paleozoic Ice Age (LPIA) add to our understanding of …

Earth has a prolonged history characterized by substantial cycling of matter and energy
between multiple spheres. The production of organic carbon can be traced back to as early …

Abstract The Late Devonian envelops one of Earth's big five mass extinction events at the
Frasnian–Famennian boundary (374 Ma). Environmental change across the extinction …

Potential temporal and causal connections among various geologic events have long been
discussed in the geological literature. More recently, signs of common periodicities in these …

We performed spectral analyses on the ages of 89 well-dated major geological events of the
last 260 Myr from the recent geologic literature. These events include times of marine and …
