Description:
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 the Oviraptor philoceratops holotype, suggests that this dinosaur may have been a brooding adult.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Norell, M A -- Clark, J M -- Demberelyin, D -- Rhinchen, B -- Chiappe, L M -- Davidson, A R -- McKenna, M C -- Altangerel, P -- Novacek, M J -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):779-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17730398" target="_blank"〉PubMed〈/a〉
