Oolithes is an oogenus with uncertain affinities. It has historical significance because it was the earliest named oogenus. James Buckman described the first named species as Oolithes bathonicae in a communication to the 4 May 1859 meeting of the Geological Society (published in 1860). Buckman believed that Oolithes represented the eggs of a teleosaurian reptile.^[1]

Since Buckman's description of O. bathonicae, two other oospecies have been named: O. nanhsiungensis and O. sphaericus, both of which were native to the Maastrichtian of China.^[2][3]
