Youngoolithus is an

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]
