Elongatoolithus excellens

† Elongatoolithus excellens is a large oospecies of oviraptorosaurian eggs from the Late Cretaceous of the Gobi Desert, Mongolia. Among the larger Elongatoolithus oospecies, its eggs attain lengths of up to 20 cm, suggesting a relatively large oviraptorosaur parent. Beautifully preserved clutches from the Djadokhta and Nemegt Formations occasionally include embryos, providing rare direct evidence linking egg morphology to specific dinosaur taxa. The Mongolian Cretaceous has yielded the world's best-documented elongatoolithid brooding record.

Time Period

Cretaceous Late Mesozoic Era

Elongatoolithus excellens lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
