The discovery of dinosaur eggs is a rarity, but we do know something about them. During the early 1920s, a team of scientists from the American Museum of Natural History in New York made an expedition to the Gobi Desert in Mongolia. Here they uncovered the remains of a small dinosaur, called Protoceratops, together with nests of eggs. These were so well preserved in the sandstone rocks that by cutting sections in order to look inside, it was possible to reconstruct models showing baby dinosaurs hatching from their eggs. These eggs were more than 80 million years old.
