The 'egg laying' cliff in China confuses the scientific community

A small cliff in China every 30 years "lays out" amazingly egg-shaped stones for scientists.

The locals in Qiannan Autonomous Region in Guizhou Province in southwestern China were amazed at the sight of smooth and round stone eggs shaped into protruding cliffs and falling to the ground, Sun September 12 reported. The cliff is named Chan D Ya (San Dan Nhai), which means "egg-laying cliff" in Chinese.

Test results show that the stones taken from Chan Dan Ya formed 500 million years ago in the Cambrian period. However, this particular cliff of Gandeng Mountain is made up of limestone that is common in many areas on Earth. In the stone eggs contain a large amount of sediment.

Experts believe that the egg-like shape of the stones results from the difference in the erosion time of each rock. But they still cannot explain how smooth stones are rounded in shape, or why the geological area dating back to half a billion years contains limestone.

People often bring stone eggs home because they believe they bring good luck.(Photo: Asiawire).

Cliffs are only 20m long and 6m high. Many villagers bring stone eggs home because they believe they bring good luck and good luck. That's why only about 70 stones are preserved.
