On April 26, a user certified by Weibo as vice president and curator of the Jiangsu Institute of Geological Survey posted that Chen Shangbin, director of the Department of Geology of China University of Mining and Technology, was on a business trip when he found fossil debris on the sink slab at Guiyang Longdongbao Airport toilet, and casually photographed the circle of friends.
According to the identification of Dr. Qian Maiping, a stratigraphic paleontologist, the fossil plate of the airport toilet in Guiyang Longdongbao is: Stone Gangular Shell Shell, and the biological classification belongs to the five-room shell, the branch shell family, and the pseudo-shell shell genus. It is about 439 million years old.
Some geologists joke that the men's toilet at Guiyang Airport has the potential to become a popular punch card.
The fossils of the washstand were scattered and separated, indicating that they were buried rapidly when they formed, apparently a storm or tsunami accumulation. The early Shiliu Caledonian Movement in Guizhou was characterized by large-scale uplifts into shallow basins, where storms could spread to the seabed, forming rapid hybrid accumulations, and tsunamis caused by tectonic activity also formed rapid accumulations.
Because the proposed house in Guizhou was scattered and broken, it was cut into building plates for sale.
Similarly, there are owl shell fossils in Guangxi, because they are well preserved (the two shells are combined, there is no separation and scattering), which can be sold as ornamental fossils, and the value is much more expensive than the shell shells!
This is the Shell Shell of the Stone Cast, with a scale of 10 mm.
