In a groundbreaking study, researchers have uncovered evidence suggesting that dinosaurs were thriving in North America just before the asteroid impact that led to their mass extinction 66 million years ago.

This latest insight, published in the journal Science, challenges previous beliefs that dinosaurs were already in decline before the catastrophic event. By analyzing fossils in New Mexico's Kirtland Formation, dating back 400,000 years prior to the asteroid strike, scientists have revealed a diverse range of species.

However, experts caution against drawing broad conclusions as the findings are based on a single site. Accurate dating of dinosaur remains presents challenges, and further research is needed to understand the global picture of dinosaur existence on the eve of their extinction.
