Story summary

A groundbreaking study from University College London reveals that dinosaurs may not have been in decline before the catastrophic asteroid impact 66 million years ago. By examining over 8,000 North American fossils, researchers discovered that perceived drops in diversity could be attributed to inadequate fossil records, not dwindling populations. Geological shifts likely obstructed fossilization, reshaping our understanding of extinction.
