The boy went to the Yangtze River to look for stones, but at this moment, he inadvertently found a black stone that did not slip in autumn, gray and was covered with sand and dust
Because it is against the sun, the nail lines on the surface of the stone have attracted special attention from the young man, and after taking it home, they have published it online for identification, and the result has surprised the boy.
Fossils of hui wood are a type of tree fern that grew in the Permian period of about 200 million years ago, the tree is 10 meters high, when it grew luxuriantly, and it is a coal-forming plant. The wood fiber of hui wood, after being silicified, is hard and siliceous, called silicified wood or wood fossil.
Fossils of hui wood, that is, fossils of tree ferns, grew in the permian of the geological era 200 million years ago, semi-negative tree species, prefer warm and humid climates, and often grow in groups in shrublands by valley streams. Co-existing with dinosaurs, this tree species has long been basically extinct.
The name "Huimu" may be due to the fact that it is rooted in a cross-sectional, arranged in a radial manner, describing it as "radiant" as the sun's brilliance. The texture of the pyrene stone is hard, the pattern and color are beautiful and abnormal, so such fossils are very precious
