Coralloidoolithus shizuiwanensis

An ootaxon from the Late Cretaceous Shizuiwan locality of China, Coralloidoolithus shizuiwanensis is named after its type locality. The coral-like eggshell microstructure of this egg type distinguishes it within the oofamily Coralloidoolithidae. Chinese Late Cretaceous oological diversity is among the richest in the world, reflecting the diversity of dinosaur nesters in East Asian ecosystems.

Time Period

Cretaceous Late Mesozoic Era

Coralloidoolithus shizuiwanensis 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.
