Fossils from the Cretaceous era that carry significance for a previous scientific research were discovered in several areas of Inner Mongolia in northern China.
On Friday, Institute of Geo-environment Monitoring of Inner Mongolia Division head Li Yaoquan announced the discovery of fossilized Cretaceous dinosaur eggs and other old-world animals in several localities including Erdos City, Alxa League and Hulun Buir City.
"These [discoveries] will be important for research of geological formation and movement," Li stated, explaining that the fossils will provide significant information about the appearances of the ancient creatures particularly their shapes and structures as well as their lifestyle and habitat.
The Cretaceous era had been home to the last dinosaurs that walked the Earth, beginning some 137 million years ago and ending after 70 million years.
Fossils found during this era were concrete proof that dinosaurs did exist and that they had evolved and become extinct after several million years of roaming the planet.
Earlier last month, the Proceedings of the National Academy of Sciences revealed the discovery of the earliest known lamprey larva fossils in Inner Mongolia.
According to experts, these creatures have ventured the Earth about 125 million years ago.
Desui Miao, collection manager of the University of Kansas Biodiversity Institute, explained that these oldest identified fossilized creatures displayed stages of both pre-metamorphosis and metamorphosis.
"To understand the whole arc of vertebrate evolution, we need to know these animals. The biology of the lamprey holds a molecular clock to date when many evolutionary events occurred," he added, noting that the eel-like lamprey may hold significant clues about the roots of humanity.
Miao further explained that some features of the human body came from the jawless fishes which slowly evolved since the Devonian about 400 million years ago.
