Mysterious egg-laying cliff in China baffles scientists

There is a mysterious egg-laying cliff in China that baffles scientists.

The strange phenomenon is observed over an area of 66 feet long and 20 feet wide on a mountain at Gulu Zhai village and ‘has produced rock spheres for hundreds of years.’

The strange ‘egg-laying cliff’, or ‘chan dan ya’ in Chinese, reportedly drops ‘stone eggs’ once every 30 years.

The unnamed mountain in the Gulu Zhai village measures 20 metres long (66 feet) and six metres wide (20 feet).

The ‘stone eggs’ have a diameter of between 30 and 60 centimetres (11.8 inches and 23.6 inches) and could weight up to 300kg (660 pounds). They would reportedly grow from the cliff face and eventually drop to the ground every 30 ears or so.

The mysterious stone eggs have a dark blue colour and look like dinasour eggs.

Local residents collect the spheres and worship them to pray for good luck and help the newly wed couples to have baby boys.

Over the years, geologists in China have provided some possible explanations to the cause of the phenomenon. or some, the ‘stone eggs’ were lumps formed by calcium carbonate molecules in the deep sea around 500 million years ago during the Cambrian Period.

The deep sea turned into high mountains over time, and these lumps became lodged in the mountains. And because mudstone, which forms the mountains, weathers more quickly than the lumps, it appears that the cliff is giving birth to the ‘eggs’.

Others argue that these stone eggs are made up of silicon dioxide.

Such mysterious stone egg phenomena are observed around the world in New Zealand, Russia and Bosnia.
