Elongatoolithidae

† Elongatoolithidae is a family of elongate dinosaur eggs attributed to oviraptorosaurs, widespread across Late Cretaceous Asia and extending into South America. Characterised by their elongated oval shape and distinctive branching pore canals in the eggshell, they are found in organised clutches typically arranged in two concentric rings. Elongatoolithid eggs are frequently associated with nesting theropods caught on the nest, providing some of the best dinosaur brooding evidence. The family includes numerous genera and species.

Diet & Feeding

Carnivore

Elongatoolithidae 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

Elongatoolithidae 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.
