A fossil soft-shell egg has been discovered in Antarctica. The egg is a large, football-sized egg believed to have been left by an ancient marine reptile known as a mosasaur. The fossil was estimated to be 66 million years old, as iflscience details:
"It is from an animal the size of a large dinosaur, but it is completely unlike a dinosaur egg," said lead author Lucas Legendre, a postdoctoral researcher at the University of Texas Austin's Jackson School of Geosciences,” in a statement. "It is most similar to the eggs of lizards and snakes, but it is from a truly giant relative of these animals."
It was previously believed that giant marine reptiles from the Cretaceous did not lay eggs, yet “nothing like this has ever been discovered.” Chilean scientists first came across the fossil nearly a decade ago, after which it sat unlabeled in the country’s collections at the National Museum of Natural History. Scientists referred to the more than 28-by-18-centimeter (11-by-7 inches) stone-like fossil simply as “The Thing”.
