Paleontologists agree that a massive asteroid strike triggered the end of the dinosaurs, but a debate has persisted over the reptiles’ overall state at the time of the fateful collision.

Dinosaurs weren't in decline when an asteroid smashed into Earth and wiped them out, scientists say. Instead, the idea that dinosaur diversity was declining before the asteroid struck 66 million ...

The aftereffects of the collision resulted in the extinction of an estimated 75% of animal species, including most dinosaurs except for birds. But practically nothing of the asteroid itself remains.

The asteroid responsible for our last mass extinction 66 million years ago — wiping out the dinosaurs — originated from the far reaches of our solar system, unlike most asteroids that have ...

It’s a long-debated issue, but now researchers say the idea Dinosaurs were in decline before the Chicxulub asteroid struck 66 million years ago could be due to fossil collection practices.

The extinction of the dinosaurs has been a hotly debated topic for decades, and whether it was an asteroid, a volcanic eruption or even poisonous plant species. But researchers have found hard ...

A new study suggests that dinosaurs likely weren't in decline before an asteroid wiped them out 66 million years ago; instead, there may just be limited fossils from that time period, challenging ...

In other words, were dinosaurs increasing or decreasing in diversity in the years ahead of the asteroid? Recent research in PNAS attempts to answer these questions. Relying on fossilized dinosaur eggs ...
