Historical findings

A dinosaur egg fossil dated back to the Late Cretaceous was discovered by primary school student named Zhang Yangzhe while playing near the Dong River in 2019 in July. The boy's mother, Li Xiaofang, later contacted the Heyuan Dinosaur Museum members, and under their excavation guidance more than 10 dinosaur egg fossils each about 9 centimeters in diameter and dating back to 66 million years were revealed.^[5][6][7]
