Yale University ecologists reveal a lizard lineage that rode out the dinosaur-killing asteroid event with unexpected ...

The Cretaceous-Paleogene mass extinction, occurring approximately 66 million years ago, represents one of the most dramatic biotic crises in Earth’s history.

The Cretaceous period is known for the K-Pg extinction event. This event happened approximately 66 million years ago. During this time, many invertebrates and large vertebrates became extinct.

Eventually, time tempered the catastrophic climate of the KT extinction event. As conditions became livable again, survivors of the event flourished and diversified. These organisms are the ancestors ...

Perhaps the most well-known extinction is the Cretaceous-Paleogene (K-Pg) extinction event, which took place 66 million years ago. We all know about it because it was the event that wiped out the ...

The Cretaceous-Paleogene (K-Pg) mass extinction event, which occurred roughly 66 million years ago, was Earth’s last major extinction event and is estimated to have resulted in the removal of 55 ...

The Cretaceous-Paleogene (K-Pg) mass extinction event, as it is known, sparked drastic ecological changes around the world. This eventually led to the extinction of approximately 55-76 percent of ...

When physicist Luis Alvarez and his team discovered the Cretaceous-Paleogene iridium boundary in 1980, their conclusion that an iridium-rich asteroid had hit the Earth and caused the extinction of ...

However, the Cretaceous–Paleogene extinction event was not the worst loss of life in our planet’s history. That distinction belongs to the Permian-Triassic extinction or the Great Dying.

By the time the Cretaceous-Paleogene, or K-Pg, extinction event was over, about three-quarters of species alive at the time of impact had disappeared forever. Advertisement.
