Dinosaurier -Ei direkt zum ersten Mal datiert

Direct dating as defined in the article:
„To determine the age of an egg directly, the researchers fired lasers at eggshell fragments to vaporize the minerals deposited on the surface during fossilization. The resulting vapour contained lead and uranium atoms. Uranium naturally decays into lead. Because the decay happens at a consistent rate, studying the composition of decaying uranium atoms (or isotopes) and stable lead atoms trapped in geological material, such as the dinosaur eggs, reveals the fossil’s age.“
