Secrets of Cliff Stone Egg’s “Life Experience”

  There is a climbing mountain in Sandu County, Guizhou Province. This mountain is very strange. The mountain is covered with trees and weeds, except for a cliff on the side of the mountain. What’s even stranger is that some stone eggs are automatically dropped out of this cliff every thirty years, so local people are used to calling it “egg-laying cliff”.
  The egg-laying cliff is more than 20 meters long and 6 meters high. The surface is extremely uneven. At high places, several huge and sharp rocks lie across it, which is extremely steep. And the stone egg bred quietly on the relatively recessed cliff. Some have just emerged, some have already given birth to half, and some have matured and will soon be separated from the mountain.
   Why can stone eggs be born on the cold stone walls and they will automatically fall every 30 years? This mysterious phenomenon of egg-laying stones not only surpasses the logical category known to mankind, but also like a huge mist that has been shrouded in the aquatic village below Denggan Mountain.
   Gulu Village is an aquatic village in Sandu County. Since a branch of the aquatic moved to Qiannan 1,000 years ago, this village has also experienced thousands of years of wind and rain. The houses of the Shui people are the same, the clothes are the same, and the lifestyles are the same, but Gulu Village has a feature that other Shui villages don’t have, that is, almost every household collects stone eggs born from the egg-laying cliff. .
   Although there are only 20 households in the entire Gulu Village, 68 stone eggs are preserved in the whole village so far. People in Gulu Village are proud of having such a stone egg in their family, because as long as anyone has a stone egg in their house, whoever has a stone egg can thrive with humans and animals, and worry about food and clothing.
   Everyone who heard the news thought it was amazing and wanted to solve the mystery. Slowly, this matter became more and more widespread. Many people came to try to find out. Unfortunately, no one knew what it was. what happened.
   Dr. Wang Shangyan is the chief engineer of Guizhou Provincial Bureau of Geology and Mineral Exploration and Development. In June 2005, he saw the photo of the stone eggs on the egg-laying cliff, and he had the association, “From the morphological point of view, most of them are round or oval, and the color is slightly yellow. Like a dinosaur egg.”
   Dinosaur Eggs? This is a bold and surprising guess. China is the country with the largest production of dinosaur eggs in the world. Although some dinosaur bone fossils have been found in Guizhou Province, no dinosaur egg fossils have been found so far. Therefore, if these stone eggs are really dinosaur eggs, it will have inestimable scientific and economic value.
   Wang Shangyan immediately compared the stone eggs with the dinosaur egg fossils found before. He found that the average diameter of the stone eggs on the laying cliff is 30 cm, but there are also large and small. This is compared with the dinosaur egg fossils found in Heyuan, Guangdong in 1995. Regardless of the shape and size, they are very similar; in addition, although the dinosaur egg fossil has an eggshell structure, the texture exposed by long-term weathering still has many similar features compared with the stone egg.
   With so many similarities, does it mean that these stone eggs are dinosaur eggs? If the answer is yes, then there is a bigger doubt that cannot be explained-the geological age of Guizhou belongs to the Triassic, and the appearance of dinosaurs is 50 million years later than the Triassic! So how could dinosaur eggs be discovered in the Triassic strata before the dinosaurs?
   If it’s not a dinosaur egg, what exactly is the stone egg that was born automatically? In order to determine the nature of these stone eggs, only on-site inspections can be done. Without further ado, Wang Shangyan immediately set off with his companions and rushed to Sandu County to find out. As soon as he arrived in Sandu County, Wang Shangyan hurried to Denggan Mountain.
   The phenomenon of stone egg digging is very serious here. The tools Wang Shangyan brought came in handy immediately. Although he had worked in geology for 30 years, he couldn’t restrain his excitement when he came into contact with this spectacle so close. Could these rare stone eggs be dinosaur eggs?
   “These stone eggs are obviously not dinosaur egg fossils. Generally, dinosaur eggs are mostly spindle-shaped in shape and should have a shell. This stone egg has no shell; except for the shell, the inside structure of the dinosaur egg is the same as the egg white. And egg yolk, then there must be uneven clumps in it, and the rock we see obviously has a relatively uniform structure in it.” Wang Shangyan explained.
   Wang Shangyan not only collected all required rock samples on the egg-laying cliffs, but also extensively surveyed the geological environment around Sandu County, and collected similar rock samples from the surrounding areas and brought them back to the laboratory. He hopes to reveal its mystery by determining the geological age of these stone eggs.
   After measurement and analysis, Wang Shangyan discovered that the geological age of the stone eggs was the Cambrian, which is 500 million years old. Wang Shangyan also discovered that the stone wall on the egg-laying cliff was made of a kind of mudstone, and the stone egg turned out to be a limestone structure commonly seen in many places. How did the stone egg made of such common limestone get into the Cambrian stone 500 million years ago?
   In the Cambrian period 500 million years ago, Sandu, Guizhou, was still a deep sea. At that time, some calcium carbonate molecules were free in the soft mud of the deep sea. Under certain chemical action, they gradually condensed together to form nodules. After the continuous pressure of upper sediments In fact, the ooze and nodules have become rocks buried in the deep sea, the ooze has become mudstone, and the nodules have become stone eggs. After hundreds of millions of years of geological movement, they are finally exposed to the surface.
   When the stone eggs are formed and exposed to the surface. Due to differential weathering, the cliff walls made of mudstone have a fast weathering speed, while the stone eggs formed by nodules have a slow weathering speed. When the mudstone layers are weathered and peeled off, the stone eggs will slowly grow out. Because the weathering speed of the surrounding rock and the stone egg differs by about 30 years, the stone egg automatically falls off and rolls to the foot of the mountain every 30 years or so under the action of gravity.
