Dinosaur Eggshells Reveal Fossil Ages

Researchers led by paleontologist Ryan Tucker from Stellenbosch University have developed a method using uranium-lead radioisotopic dating on dinosaur eggshells to determine their ages and the ages of surrounding fossils. This method was applied at sites in Utah and Mongolia, revealing precise ages that align with geological data. Notably, the Mongolian eggs' sediment also suggested a meteor impact around 99 million years ago. This breakthrough could transform paleontological dating accuracy across different sites.
