Earth's history is marked by violent mass extinctions that have shaped life on the planet. Here's how many of these events ...

A new analysis suggests that recent extinctions have been rare, limited mostly to islands and slowing. But others argue this is all just semantics.

The planet is seeing a decline in biodiversity, but extinctions are relatively rare and don’t meet the threshold for a sixth ...

A mass extinction event is a term used to describe a large-scale event that wipes out species. It is usually not a short, one-time incident but rather something that occurs over thousands or millions ...

Known as “the Great Dying,” the extinction event was marked by supervolcanic eruptions that expelled greenhouse gases in an Australia-size region known as the Siberian Traps in Eurasia. That led to ...

Dinosaurs' extinction "re-engineered" Earth's surface, according to new research. The reptiles had such an "immense" impact ...

The Jurassic Period is one of the three prehistoric geological periods of the Mesozoic Era. It spans from 145 million to 201 million years ago. This period was preceded by the Triassic Period and ...

At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts ...

Dinosaurs had such an immense impact on Earth that their sudden extinction led to wide-scale changes in landscapes—including ...

New research shows that while many species have disappeared, extinctions of genera are very rare across plants and animals.

Despite Earth's most devastating mass extinction wiping out over 80% of marine life and half of land species, a group of early reptiles called archosauromorphs not only survived but thrived, venturing ...
