Studies of dinosaur eggs flourish in southern China

In the coastal province of Guangdong, dinosaur eggs have also been found in Nanxiong, Huizhou and Foshan in the Pearl River Delta region and Maoming in the western part of the province.

Dinosaur eggs found in Guangdong date back to both the earliest and late stages of the Cretaceous Period, said Wang.

"Dinosaur eggs unearthed in other areas are generally of a single type. From the perspective of geological age, eggs discovered in Heyuan play a connecting role in the dinosaur egg fossil group in China," he said.

Unlike fossils usually found in soft soil elsewhere, dinosaur eggs in Heyuan are mainly found in rough red sandstone, added Wang.

Among all the areas in China where dinosaur eggs were found, Heyuan is the only place where dinosaurs had laid their eggs in rough "delivery rooms", according to Wang.

"It provides more possibilities for future research on the living environment of dinosaurs in Heyuan, and also reflects the adaptability of these dinosaurs to the environment," he said.
