New theory explains possible origin of the Armageddon-causing object. It forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub…
New research suggests that overhunting by humans was not responsible for the extinction of mammoths, ground sloths, and other North American megafauna. A new study…
The idea that mass extinctions allow many new types of species to evolve is a central concept in evolution, but a new study using artificial…
Researchers find that timing of mass extinctions lines up with asteroid impacts and massive volcanic eruptions. Mass extinctions of land-dwelling animals — including amphibians, reptiles,…
A new statistical analysis of dinosaur diversity shows they were not in decline at the time of their extinction by an asteroid hit 66 million…
Researchers in Japan, the US, and China say they have found more concrete evidence of the volcanic cause of the largest mass extinction of life….
Scientists show the unfolding of one of the largest mass extinctions in Earth’s history. Earth’s history knows catastrophes that are unimaginable for humans. For example,…
New study provides a comprehensive reconstruction of the Permian-Triassic boundary event. Life on Earth has a long, but also an extremely turbulent history. On more…
Between a decline in biodiversity and a series of extinction events, the Late Devonian period was not the most hospitable time on Earth. And then…
It’s not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In…
Imagine reading by the light of an exploded star, brighter than a full moon – it might be fun to think about, but this scene…
A team of University of Rhode Island scientists and statisticians conducted a sophisticated quantitative analysis of a mass extinction that occurred 215 million years ago…
New dates for fossils indicate land animal turnover extended for hundreds of thousands of years. The mass extinction at the end of the Permian Period…
The world is waking up to the fact that human-driven carbon emissions are responsible for warming our climate, driving unprecedented changes to ecosystems, and placing…
When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis, and blasted so much sulfur into the…
Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and…
The greatest mass extinction pulse was the Permian-Triassic extinction event, and it happened about 250 million years ago, nearly wiping out life on Earth. It…
Paleontologist Alim Reisdorf and the co-authors of a new study published in the journal Paleobiodiversity & Paleoenvironments have been trying to figure out exactly how…
