Megaloolithus is an oogenus of dinosaur egg.[1] They are thought to have been laid by sauropod dinosaurs. They are known for having thick eggshells, at least 1.5 millimetres (0.059 in) thick, and the nearly spherical shape of the eggs.[2] They are primarily found in India and Europe, but some specimens have been found in South America.[3]
