Dinosaur - Extinction Causes, Evidence, & Theory

Dinosaur Extinction Debate: Decline or Dominance Before the Asteroid?

About 66 million years ago, the Cretaceous Period drew to a dramatic close as non-avian dinosaurs disappeared alongside roughly 75 percent of Earth’s species. This Cretaceous-Paleogene event reshaped life on the planet, paving the way for mammals to rise. While a massive asteroid impact stands as the frontrunner explanation, fossil records from North America hint ...
