The "Big Five" mass extinctions of the Phanerozoic Eon have long attracted significant attention from the geoscience community and the public. Among them, the Late Ordovician Mass Extinction (LOME ...

This estimate is in good agreement with the number of unexplained mass extinction events on Earth — specifically, the Devonian and Ordovician extinctions, both of which occurred within the last ...

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, ...

The fossil record of mass extinctions older than 300 million years is a bit sketchy, as life existed only in the sea at the time. The end-Ordovician mass extinction correlates with the Suordakh ...

A time when the first-ever mass extinction may have turned Planet Earth into Sponge World. The end of the Ordovician period was a pretty terrible time to be alive. I don't know if you remember it ...

The biggest mass cataclysm of all time, called the end-Permian extinction, occurred 252 million years ago. Some 95% of species disappeared on land and at sea as a result of global warming — with ...

It’s called the Late Ordovician mass extinction. Back then, most living things were in the ocean. About 85% of them died. Scientists think it happened for two reasons.

As scientists say we’re in a sixth mass extinction, ... (492 feet) lower, respectively — played a major role in the earliest identified mass extinction event, the end-Ordovician, according to ...

At least five times, a biological catastrophe has engulfed Earth killing off the vast majority of species. As scientists say we’re in a sixth mass extinction, what can we learn from the past?
