Millions of years ago – long before even the strike of the dinosaur-killing asteroid – a Protoceratops laid a dozen eggs in an area that would later be the Gobi Desert of Mongolia. Yet those eggs never hatched and instead became frozen in the mists of time. And eventually, against all the odds, they were discovered by scientists and made their way to the vaults of the American Museum of Natural History in New York. Then, in 2017, experts used a new approach to take a closer look at the fossilized eggs. And what they found could change what we thought we knew about the dinosaurs.
