The end of the Ordovician, in contrast, was kicked off by the Earth’s thermostat firmly flipping to “cold” – and much like ...

This unprecedented die-off is now known as the earth’s first mass extinction, the Late Ordovician mass extinction or simply LOME. Many researchers have devoted time, or even careers, to uncovering the ...

“It’s one of the more novel hypotheses for the Ordovician extinction that I’ve heard,” says University of California, Davis paleoclimatologist Howard Spero, who was not part of the study.

As per a study published in the Monthly Notices of the Royal Astronomical Society, the late Devonian extinction (about 372 million years ago) and the Ordovician extinction (about 445 million years ...

Instead, the team hypothesized a stellar explosion may have been a potential factor in the Late Devonian extinction event 372 million years ago and one at the end of the Late Ordovician 445 ...

They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.
