Hadrosaurs were large dinosaurs, growing up to 10 metres in length, belonging to the ‘Duck-Billed’ group of dinosaurs. They are considered the ‘herd animal’ of the Cretaceous, having been found buried together in their thousands. Dinosaur egg fossils are known from approximately two-hundred sites around the word, particularly in Asia. This nest comes from the Xixia Formation, Henan region of China, which produces some of the best preserved eggs in the world. These eggs can yield entire embryos within them, making them an essential tool for understanding the biology of these creatures.
