Duovallumoolithus shangdanensis

†Duovallumoolithus shangdanensis is a dinosaur egg oöspecies from Late Cretaceous deposits of Shangdan Basin, Shaanxi Province, China. Its eggshell is defined by double-grooved ridges (duovallumate ornamentation) on the outer surface. Attributed to herbivorous dinosaurs, these eggs add to the diverse ootaxonomic record of Late Cretaceous China.

Diet & Feeding

Herbivore

Duovallumoolithus shangdanensis was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Cretaceous Late Mesozoic Era

Duovallumoolithus shangdanensis 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.
