Faveoloolithidae is an oofamily of dinosaur eggs. It contains Faveoloolithus, Hemifaveoloolithus, Parafaveoloolithus, and probably Sphaerovum.[1] However, unlike the other Faveoloolthids, Sphaerovum has compactituberculate ornamentation more similar to megaloolithids.[2] Like Dictyoolithidae, the membrane and the calcareous part of the eggshell formed simultaneously instead of forming the membrane before the calcareous like modern birds.[3]
