Coralloidoolithus verrucarius

A Late Cretaceous ootaxon from Mongolia, Coralloidoolithus verrucarius ('warty coral egg') bears distinctive warty nodules on its eggshell surface, reflected in its species epithet. Found in the rich oological record of the Gobi Desert, these eggs contribute to the remarkable diversity of dinosaur reproductive strategies documented from Mongolian Campanian and Maastrichtian sediments.

Time Period

Cretaceous Late Mesozoic Era

Coralloidoolithus verrucarius 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.
