HOHHOT, Nov. 7-- Paleontologists have discovered fossils from the Cretaceous Period at multiple sites in north China's Inner Mongolia Autonomous Region, providing precious evidence for scientific research.

Fossils of cretaceous dinosaur eggs and a host of other fossilized ancient animals have been found in localities under Alxa League, Erdos City and Hulun Buir City, Li Yaoquan, division head of the Institute of Geo-environment Monitoring of Inner Mongolia, told Xinhua on Friday.

Li said the fossils are of significant scientific and ornamental values, as they shed new light on the shapes and structures of ancient animals as well as their living conditions.

"These [discoveries] will be important for research of geological formation and movement," Li added.

The last era of dinosaur rule, the Cretaceous Period began 137 million years ago and ended 70 million years later. It saw the thrive of dinosaurs, and fossils of this era provide important evidence about the evolvement and extinction of dinosaurs.
