"Uncovering Dinosaur Secrets: Organic Material Found in Eggshell Fossils"

Scientists have detected ancient amino acids in dinosaur eggshell fossils, providing a rare opportunity to study organic remains from dinosaurs that lived 66 to 86 million years ago. The amino acids, found to be racemic, were preserved within the calcite mineral of the eggshells, offering insights into the biology of extinct organisms. This discovery may help researchers understand molecular changes in fossils over long periods of time and unlock secrets about ancient life through stable isotopes.
