First dinosaur eggs were soft like a turtle's
New research suggests that the first dinosaurs laid soft-shelled eggs -- a finding that contradicts established thought. The study analyzed the eggs of two vastly different non-avian dinosaurs and found that they resembled those of turtles in their microstructure, composition, and mechanical properties. The research also suggests that hard-shelled eggs evolved at least three times independently in the dinosaur family tree.
