Parvoolithusis anoogenusofMongolianfossil eggsfrom theCampanianBarun Goyot Formation.They are known from a single small, smooth egg, which cannot be assigned to any known oofamily.[1]It is very similar to the eggs of modern birds in many aspects; in fact, acladistic analysisby Zelenitsky and Therrien found it to be a sister taxon to the guinea fowl (genusNumida), indicating that they represent the eggs of birds, rather than a non-avialantheropod.[2]
