Mass extinction events represent intervals of abrupt, large‐scale loss of biodiversity that have repeatedly reshaped life on Earth. These crises are commonly linked to dramatic environmental ...

The Silurian Period is characterised by a dynamic interplay between environmental stressors and biotic turnover, with extinction events and carbon isotope excursions (CIEs) representing pivotal ...

Most people think of crocodilians as living fossils—stubbornly unchanged, prehistoric relics that have ruled the world's swampiest corners for millions of years. But their evolutionary history tells a ...

(CNN) — No species lasts forever — extinction is part of the evolution of life. But at least five times, a biological catastrophe has engulfed the planet, killing off the vast majority of species from ...

Asteroid impacts and volcanism have led to mass extinctions on our planet. Illustration by Emily Lankiewicz / NASA / Public Domain Life’s first major catastrophe crept across the planet with the ...

It had quite an impact — striking with the force of 10 million atomic bombs. Sixty-six million years ago, the asteroid that slammed into what is now the Yucatán Peninsula caused a mass extinction ...

Whether a species has just freshly emerged, or it has been around for millions of years does not dictate its vulnerability.

Among sharks and rays, species within the first four million years of existence are significantly more likely to go extinct than older species, according to a study led by researchers from the ...

(CNN) — A cataclysm engulfed the planet some 252 million years ago, wiping out more than 90% of all life. Known as the Great Dying, the mass extinction that ended the Permian geological period was the ...

Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their ...
