Shell-rich rocks trace a mostly upward climb in ocean life, with each mass extinction slashing both diversity and biomass ...

In 2015, two members of the Blue Beach Fossil Museum in Nova Scotia found a long, curved fossil jaw, bristling with teeth.

In a first-of-its-kind study, Stanford researchers have measured how the abundance of ocean life has changed over the past ...

The large fish, spanning nearly a metre on the lake bed, lived in waters thick with rival fish, including giants several times its size ...

Douglas McIntyre, Editor-in-Chief at Climate Crisis 24/7, reports on new research from The Guardian showing that over 500 bird species could go extinct within the next century due to the climate ...

A Pattern of Extinctions According to Our World in Data, Mass extinctions are not new to Earth. For over 500 million years, the planet has experienced five major biological crises, during which at ...

Earth has already faced five mass extinctions—and scientists say the sixth has begun. Species are vanishing, climates are shifting, and humans may be next. Is there any way out of this?

Marine bivalves lost around three-quarters of their species during this mass extinction, which marked the end of the Cretaceous Period. My colleagues and I – each of us paleobiologists studying ...

A new fossil study reveals that after the asteroid-induced mass extinction 66 million years ago, marine ecosystems remarkably retained all ecological niches despite losing most species, an outcome ...

66 million years ago, an asteroid caused a mass extinction that wiped out around 70% of species, including many marine creatures. Remarkably, bivalves, despite losing many species, retained their ...

Mass extinctions clearly upend the status quo. Now, our ocean floors are dominated by clams burrowed into sand and mud, the quahogs, cockles and their relatives – a scene far different from that ...
