Youngoolithus is an oogenus of dinosaur egg.[1] It is the sole member of the oofamily Youngoolithidae, and consists of a single oospecies: Youngoolithus xiaguanensis. It consists of a single fossil nest of 16 eggs with an associated dinosaur footprint that was first discovered in 1975 in the Majiacun Formation near , Henan Province, in the Cretaceous Xiaguan Basin. The eggs are smooth, olive-shaped, and arranged in five rows. It was originally described as being a Faveoloolithid egg, however the nest is arranged quite differently than other members of that family, so it has been moved to its own oofamily, Youngoolithidae.[2][3]
