In 1923, scientists gave the name Oviraptor philoceratops (egg eater) to a dinosaur they found lying on top of a nest of what they thought were Protoceratops eggs. A similar egg was subsequently found containing an almost complete skeleton of an Oviraptor embryo. It is now believed that the Oviraptors were actually protecting and nurturing their own eggs rather than raiding the nest. This egg is 6in x 2in.
