Turns out, dinosaur eggshells are way more than just fossilized breakfast—they’re literal time machines! Scientists just figured out that radioactive isotopes inside the shells act like built-in clocks, letting them pinpoint exactly when those eggs were laid and fossilized. Using lasers and mass spectrometry, they can now date dino nests to the million-year mark, totally rewriting the timeline of dinosaur evolution and extinction. Imagine cracking open an egg and finding the exact moment in history inside! #Science #Dinosaurs #ScienceNews
