It was a fearsome predator that lived during the Late Jurassic Period millions of years before Tyrannosaurus rex. This image shows a young female Denisovan, reconstructed based on DNA methylation maps. Under a microscope, the halos resembled a protein-heavy eggshell membrane that has been found as the innermost layer of crocodile and bird eggs. Previously, it was believed that mosasaurs had live birth, said Julia Clarke, study coauthor and professor in the University of Texas at Austin's Jackson School's department of geological sciences. They provide evidence that dinosaurs laid soft-shell eggs. The unusual features of this hatchling also suggested it lived in a different habitat and different conditions, but the researchers won't know more until they discover other examples of this in the fossil record.

Once hatched, the baby mosasaurs would make their way to the ocean — not unlike baby sea turtles. "From an evolutionary perspective, this makes much more sense than previous hypotheses, since we've known for a while that the ancestral egg of all amniotes was soft," said Matteo Fabbri, study coauthor and a graduate student at Yale University's department of geology and geophysics, in a statement.
