We document three aspects of microbialite resurgence that followed the Late Ordovician extinction event (LOEE) using centimetre-scale sedimentological logs of carbonate rocks deposited on the ...

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 ...

The events that triggered the Late Ordovician Mass Extinction or LOME of marine animals and plants has largely remained a mystery until now.

The Late Ordovician mass extinction, the oldest of all and the second most lethal, isn’t one of them. Though there is a standard explanation for this granddaddy of death — involving an ancient ice age ...

A second theory that has gained some traction, ties both waves of extinction to the warm periods that bookend the ice age. In a 2020 paper, two geologists assert that a large volcanic eruption may ...

Researchers suggest supernovas may have caused two major mass extinctions on Earth, possibly factors during the Late Devonian and Late Ordovician periods.
