Scientists from Osaka Metropolitan University have discovered that ancient reef-building organisms called stromatoporoids survived the Late Devonian mass extinction event and continued to thrive ...

Based on this, the team determined that 2.5 near-Earth supernovae occur per billion years —a figure that matches the timing of the Late Ordovician and Late Devonian extinctions.

While the Late Devonian Mass Extinction left forests unperturbed, disaster befell life in the ocean. Almost 73 million years after the late Ordovician mass extinction, or 375 million years ago, half ...

Melvyn Bragg and guests discuss one of the five major extinction events on Earth so far.

I call the Late Devonian my favorite mass extinction primarily because it shows that humans are far from the only organism to remake the Earth.

Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass ...

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

Earth has experienced five mass extinction events over its 4.5 billion-year history. A sixth mass extinction is underway as a result of human-driven climate change.

It killed off about 70 percent of all species. The Late Devonian Extinction, as it's called, snuffed out a lot of marine life, including armored fishes and reef-building creatures.

The late Devonian extinction event, for example, was really a series of extinction pulses, spread out over 20-25 million years. Anatomically modern humans have been here for 200,000 years, tops.

Diverse and full of sea life, the Earth's Devonian era—taking place more than 370 million years ago—saw the emergence of the first seed-bearing plants, which spread as large forests across the ...

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 ...
