Dinosaur Extinction Reshaped Earth's Geology, Not Just Its Fossils

Sixty-five million years ago, the vanishing of the great dinosaurs did not merely empty the skies and plains — it quietly rewrote the geology of continents. A new study suggests these creatures were not passive inhabitants of their world but active architects of it, their immense bodies suppressing forests and keeping rivers wild. When they disappeared, trees returned, rivers settled into gentle meanders, and the land itself recorded the absence in stone — a reminder that life and landscape have always shaped one another in both directions.
