An embryonic skeleton of a nonavian theropod dinosaur was found preserved in an egg
from Upper Cretaceous rocks in the Gobi Desert of Mongolia. Cranial features identify the
embryo as a member of Oviraptoridae. Two embryo-sized skulls of dromaeosaurids, similar
to that of Velociraptor, were also recovered in the nest. The eggshell microstructure is similar
to that of ratite birds and is of a type common in the Djadokhta Formation at the Flaming
Cliffs (Bayn Dzak). Discovery of a nest of such eggs at the Flaming Cliffs in 1923, beneath …
