Oolithes is an oogenus with uncertain affinities. It has historical significance because it was the earliest named oogenus. The first named species was Olithes bathonicae, which was described in 1860 by J. Buckman, who believed that Oolithes represented the eggs of a Teleosaurian reptile. Since then, two other oospecies have been named: O. nanhsiungensis and O. spheroides, both of which were native to the Maastrichtian of China.
