Dinosaurs ruled the Earth for over 150 million years. Compared to the mere 4–6 million years that scientists believe humans and their earliest ancestors have been on the planet, it wouldn’t be ...

SAN DIEGO - In what researchers describe as a historic step toward de-extinction science, an international team of gen ...

New plankton arrived just a few millennia — maybe even decades — after the Chicxulub asteroid, forcing a rethink of evolution ...

A newly described dinosaur that appears to have persisted beyond a catastrophic die-off is forcing scientists to rethink how mass extinctions actually play out on the ground. Instead of a clean break ...

Who knows what life would have looked like on Earth if an extinction-level event hadn't killed all of the dinosaurs? I highly doubt the dinosaurs would have let us evolve and take over the planet the ...

Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact ...

The researchers are not the first to propose that the space rock belonged to a group of asteroids that formed beyond the orbit of Jupiter. Their findings, however, strengthen the case thanks to a rare ...

Throughout the past 600 million years there have been five major mass extinction events that devastated life on Earth. While some of these events are very well studied, such as the killer asteroid ...
