After years of detective work, University geosciences professor Gerta Keller and her colleagues have found that an intensive period of volcanic eruptions and a series of asteroid impacts likely ended ...

Fossils reveal dinosaurs were flourishing in diverse ecosystems right up until the asteroid impact ended their reign. Their abrupt extinction reshaped Earth’s ecosystems and set the stage for mammals ...

For a long time, the prevailing theory was that dinosaurs were already in decline before the Chicxulub asteroid struck Earth approximately 66 million years ago, leading to the extinction of about 70% ...

New research indicates that dinosaur populations in North America were thriving just before the asteroid impact 66 million years ago, which triggered their mass extinction. This finding offers a fresh ...

Scientists have long debated whether dinosaurs were in decline before an asteroid smacked the Earth 66 million years ago, causing mass extinction. New research suggests dinosaur populations were still ...

Dinosaurs weren’t dying out before the asteroid hit—they were thriving in vibrant, diverse habitats across North America. Fossil evidence from New Mexico shows that distinct “bioprovinces” of ...

Scientists studying the Chicxulub crater have made strides in understanding the formation of central rings in large impact ...

The asteroid that wiped out the dinosaurs may not have been the whopper scientists thought. Analysis of chemical remains of the asteroid that can still be found in sediments under the sea shows the ...

A massive meteorite impact and extreme volcanic activity occurred around the same time that Earth's large dinosaurs went extinct. But, did the volcanic activity play a role in the mass extinction, or ...

A ridge of rocks in New Mexico holds a snapshot of a dinosaur heyday. Fossils of crested hadrosaurs, long-necked sauropods and a variety of plants all point to a flourishing ecosystem. “Without this ...
