Fossils reveal dinosaurs were flourishing in diverse ecosystems right up until the asteroid impact ended their reign.

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 years ...

There might still be dinosaurs living on Earth today — if not for the giant asteroid. It’s a long-debated issue, but now researchers say the idea Dinosaurs were in decline before the Chicxulub ...

In a new study in Geology, researchers calculated how long it took for novel single-celled marine species to appear after the asteroid impact, and it’s surprisingly fast.

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 ...

NEW MEXICO (KRQE) — The extinction of the dinosaurs may be ancient history, but that history continues to be rewritten, thanks in part to a professor at New Mexico State University. As Chad Brummett ...

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% ...
