At the Sinlunshan fossil reserve located in the central region, scientists identified unique findings consisting of fossilized eggshells. According to the information, the age of the 28 discovered eggs is estimated to be approximately 86 million years.
Experts emphasize that most of the eggs belong to the family Dendroolithidae and are classified as the species Placoolithus tumiaolingensis. Their shape is somewhat flattened spherical, with lengths ranging from 120 to 170 millimeters, and the shell thickness does not exceed 2.4 millimeters.
These characteristics indicate the unique geological significance of the eggs. Scientists used a method called the “atomic clock” to determine the age of the eggs.
This method involves measuring lead and uranium isotopes in the eggshell to calculate an accurate age. Researchers hope that this technique will play an important role not only in age determination but also in studying how dinosaurs adapted to cold climates.
Because this information could reveal new aspects of the lives of ancient animals. The lead researcher, Bi Chjao, stressed the necessity of carefully studying the findings.
According to him, this complex process requires modern laboratory conditions and high-precision equipment. Most importantly, the samples must not be contaminated with other substances.
Experts believe that this discovery is an important step for global paleontology and will enable the identification of new information about the lives of dinosaurs and their environmental adaptations in the future.
