250 million years ago, catastrophic volcanic eruptions plunged Earth’s oceans into a toxic, oxygen-starved crisis that erased ...

The collapse of tropical forests during Earth's most catastrophic extinction event was the primary cause of the prolonged global warming which followed, according to new research. The Permian–Triassic ...

The impact dinosaurs had on Earth was so big that their extinction seems to have caused dramatic and wide-ranging changes to the planet’s landscapes, such as shifting rivers. There is a marked ...

Imagine a massive asteroid heading toward Earth, similar to the one that ended the age of dinosaurs 65 million years ago.

Mass extinction events are defined by a 75% loss in total species. These events can take tens of thousands to several million years. Experts are alarmed at today’s “unprecedented” population abundance ...

Scientists trace the dinosaur-killing asteroid to a rare meteorite, shedding new light on Earth's biggest extinction event.

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 ...

Mass extinctions are extremely catastrophic events on Earth. Throughout Earth's evolutionary history, numerous mass extinctions have occurred, with five major mass extinctions being particularly ...

Around 250 million years ago, one of Earth’s largest known volcanic events set off The Great Dying: the planet’s worst mass extinction event.... How did these species survive mass extinction events?

A Stanford-led study has provided the strongest evidence yet that warming oceans and declining oxygen levels caused Earth's largest mass extinction around 252 million years ago. The research explains ...

Earth responded to its most severe past warming event by evolving a new and bizarre type of photosynthesis that allowed a group of primitive plants to survive. Research led by the University of Leeds ...

The study of extinction dynamics in the fossil record integrates patterns of biodiversity loss with environmental and biotic drivers across geological time. Fluctuations in global diversity often ...
