Everyone knows that dinosaurs are extinct, and most people have some idea about how it might have occurred. But the exact periods in history when it happened are less well known. Was it a single ...

Around 66 million years ago, Earth endured a mass extinction event that marked the end of the Cretaceous and the start of the Paleogene period. Roughly 75% of all species vanished, including every non ...

The researchers began to suspect changes in geology was somehow related to the mass extinction of dinosaurs - called the Cretaceous-Paleogene, or K-Pg, mass extinction. They started to examine what ...

WACO, Texas — A new study published on Thursday, co-authored by researchers from Baylor University, New Mexico State University, the Smithsonian Institution and several international collaborators, ...

The Cretaceous–Paleogene (K–Pg) mass extinction event, marking the boundary between the Cretaceous and Paleogene periods approximately 66 million years ago, stands as one of the most profound ...

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% ...

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 Cretaceous-Paleogene (K-Pg) extinction event that occurred 66 million years ago is believed to have been caused by an asteroid crashing into Earth just off the Yucatan peninsula in south-eastern ...
