Crystals hidden inside dinosaur eggs at a famous fossil site are giving scientists a chance to do something that’s long proven elusive: figure out how old the ancient nests really are.
Finding these fossilized eggs’ true shelf life makes it possible to connect large-scale changes in climate to tiny shifts in the structure of eggshells, the researchers report September 11 in Frontiers in Earth Science. That, in turn, offers a new way to assess the ancient environments in which the dinosaurs nested.
