Elongatoolithus

† Elongatoolithus is a genus of elongated oviraptorosaurian dinosaur eggs from the Late Cretaceous of Asia, among the most common fossil eggs recovered from the Gobi Desert. Their characteristically elongate shape and complex prismatic eggshell microstructure with branching pore canals distinguish them from other oospecies. Clutches of Elongatoolithus eggs are found arranged in paired rows, consistent with brooding behaviour by oviraptorids. Multiple species are distinguished based on egg size, shape, and eggshell thickness.

Diet & Feeding

Carnivore

Elongatoolithus was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Late Mesozoic Era

Elongatoolithus 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.
