Calcium carbonate (CaCO3) biomineralizing organisms have played major roles in the
history of life and the global carbon cycle during the past 541 Ma. Both marine diversification …

There can be no doubt that early land plant evolution transformed the planet but, until
recently, how and when this was achieved was unclear. Coincidence in the first appearance …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Abstract The Late Ordovician (~ 459–444 million years ago) was characterized by global
cooling, glaciation and severe mass extinction. These events may have been driven by …

Global cooling has been proposed as a driver of the Great Ordovician Biodiversification
Event, the largest radiation of Phanerozoic marine animal Life. Yet, mechanistic …

The Cambrian is the most poorly dated period of the past 541 million years. This hampers
analysis of profound environmental and biological changes that took place during this …

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

Marine biodiversity increased markedly during the Ordovician Period (~ 487–443 million
years ago). Some intervals within the Ordovician were associated with unusually rapid and …

Abstract The Late Ordovician (Hirnantian) mass extinction (LOME) was marked by two
discrete pulses of high species turnover rates attributed to glacial cooling (LOME-1) and …

The diversity of life on Earth is controlled by hierarchical processes that interact over wide
ranges of timescales. Here, we consider the megaclimate regime at scales≥ 1 million years …
