The new curve reveals that Earth's temperature has varied more than previously thought over much of the Phanerozoic Eon, the past 540 million years of geologic time when life has diversified ...

The start of the Phanerozoic Eon 540 million years ago is marked by the Cambrian Explosion, a point in time when complex, hard-shelled organisms first appeared in the fossil record. Although ...

Published in the journal Science, the study presents a curve of global mean surface temperature that reveals Earth's temperature has varied more than previously thought over much of the Phanerozoic ...

A record of global mean surface temperature (GMST) throughout the Phanerozoic – the last 540 million years during which animals and plants evolved – is crucial. Over the last 500 million years ...

Humans are living in a geologic era with the most diverse life-forms — the Phanerozoic Eon. Beginning about 540 million years, the eon started with an explosion of the modern life we see today.

It turned out, the team found, that this underestimation of past warm periods extended to the entire Phanerozoic. In particular, Earth’s tropics were much warmer during these episodes than ...

Judd et al. During the Phanerozoic Eon, a vast swath of geological time that began around 540 million years ago, life diversified, populated land and endured multiple mass extinctions. All of ...

The mapping revealed clear global trends among marine, terrestrial, and lacustrine-dominated organofacies through the Phanerozoic and that widespread source rock deposition is likely not tied to ...
