During this period, the average species extinction rate drastically increased to 71.6% per 100 kyr. This study quantitatively demonstrates the dominant role of the rate of climate change in ...

Interactions between Earth and the solar system have profoundly shaped the planet’s history, influencing evolution and ...

During the Ordovician Period, a time of significant changes for Earth’s life-forms, plate tectonics and climate, the planet experienced a peak in meteorite strikes.

The researchers' idea that Earth once had rings comes from reconstructions of Earth's plate tectonics from the Ordovician period—which ran between 485.4 million years and 443.8 million years ago ...

The End-Ordovician Extinction was the first of the so-called ‘Big Five’ mass extinctions in the history of life on Earth - more than 80% of species in the oceans died out. But could you ...

Long before the dawn of humans, dinosaurs, insects or even trees, a cascade of unfortunate events threatened to end life on earth. During the Ordovician Period, around 485 to 444 million years ago, ...

Around 466 million years ago, at the beginning of the Ordovician period, ... “What makes this finding even more intriguing is the potential climate implications of such a ring system,” Tomkins ...

And that’s not all. “What makes this finding even more intriguing,” Tomkins added, “is the potential climate implications of such a ring system.”. The Ordovician period and its impact ...

If you were to look up from Earth some 466 million years ago, you might have seen a gleaming ring stretching across the sky, some scientists say.

Among them, the Late Ordovician Mass Extinction (LOME) is ... Topics. Week's top; ... During this period, ... The rate of climate change is identified as the primary control on extinction tempo.

The proposed ring system could also explain a climate quirk of the Ordovician. Within the Ordovician is a smaller period called the Hirnantian Age, characterized by a precipitous drop in temperatures.
