Megaloolithus is an oogenus of dinosaur egg.[1] Some eggs belonging to this oogenus may have been laid by the titanosaur Hypselosaurus. 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]
