One (Ordovician) was about 440 million years ago when temperatures dropped by 7 degrees in a few million years, precipitating a relatively brief ice age killing 80 per cent of living species.

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 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.

(CNN) — Famously known for its extensive ring system, Saturn is one of four planets in our solar system that have the distinctive feature. And now, scientists hypothesize that Earth may have sported ...

This period, which occurred near the end of the Ordovician, is recognized as one of the coldest in the last 500 million years of Earth’s history.

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 ...

Three researchers from Monash University, in Melbourne, Australia, examined the positions of the 21 meteorite craters that are known to be related to the Ordovician impact spike.
