Fossils of paleontology such as corals and brachiopods were found in the Mountains at the junction of Guangzhou-Foshan
(Mysterious Earth uux.cn) According to Guangzhou Daily All Media (Huang Jianyuan): Recently, Mr. Zhao, a citizen of Sanshui, reported to this newspaper that he found coral and shellfish fossils at the junction of Sanshui and Huadu in Foshan. Zhang Xianqiu, an expert in geology and paleontology, said that in this batch of fossils, at least three paleontological fossils such as corals, brachiopods, and sea lily stems can be identified. Zhang Xianqiu believes that fossils such as corals and brachiopods are typical marine fossils, and the discovery of these fossils further proves that in the Carboniferous Period more than 300 million years ago, most of Guangdong was a sea.
Miracle: He found coral fossils on the mountain
The reporter saw that Mr. Zhao found a dozen "coral fossils" and "shellfish fossils" of different sizes. The stones have a common feature, they are all gray-black, like coal. One of the larger stones can be seen after polishing, and inside the circle are some regular "patterns". "This one is a coral fossil." Mr. Zhao told reporters.
There are also some small stones, which look like modern shells on the outside, and have obvious textures on the surface, but these "shells" are "long" with the stone, and the color is also gray-black.
Mr. Zhao told reporters that he is a fossil enthusiast and usually likes to pick up stones in the wild. The fossils were found in the mountains at the junction of Sanshui and Huadu in Foshan. "It was found in an abandoned quarry, and as the quarry dug out the section of the formation, I walked down the hillside and accidentally picked up the fossils." When the fossils were first discovered, he said, there was a metallic luster on the surface, which may be related to pyrite.
"The local geological conditions are complex, with strata of different eras such as both the Carboniferous and the Devonian, and it is difficult to distinguish in chronology." Mr. Zhao said that according to his preliminary judgment, the fossils are from the Carboniferous Period, more than 300 million years ago.
Mr. Zhao also believes that these fossils may have witnessed the changes in the natural environment of Guangdong. "It's possible that it was the sea more than 300 million years ago, and then it was uplifted to land through geological movement." He guessed.
Verification: They bear witness that the Guangfo was once a sea
Zhang Xianqiu, an expert in geology and paleontology, identified this. Zhang Xianqiu said that these fossils can identify at least three kinds of corals, brachiopods, sea lily stems, etc., and from the chronological point of view, they belong to the early Carboniferous Period, dating back to about 320 million to 330 million years ago. "The environment in which corals live requires very clear water and deep water." Zhang Xianqiu said that fossils such as corals and brachiopods are typical marine fossils, and the discovery of these fossils further proves that in the Carboniferous Period more than 300 million years ago, most of Guangdong was a sea. "The process of biological evolution is irreversible, there are different biological fossils in different ages, and we can judge the geographical environment at that time according to the type of fossils." Zhang Xianqiu said.
"In the Carboniferous Period, many parts of northern Guangdong, northwestern Guangdong and central Guangdong were marine environments." Zhang Xianqiu told reporters that coral and brachiopod fossils have also been found in many Carboniferous strata in northern Guangdong.
Evidence: Zhaoqing has also found fossils of marine life
Coincidentally. In addition to the marine fossils such as corals and brachiopods found at the junction of Guangzhou-Foshan, a large number of shellfish fossils have also been found in Zhaoqing. According to Ling Jingsheng, a geological expert in Zhaoqing, on the mountain of Zhaoqing Banana Garden, a large number of marine shellfish fossils such as banana leaf shellfish, long-body shellfish and stone swallows have been found, which are typical fossils of the Middle Devonian Period 350 million years ago, which is a strong evidence that this place was shallow at that time.
Ling Jingsheng said that there are more than 20 kinds of marine shellfish fossils in Jiaoyuangang, which were discovered many years ago during the construction of Xijiang North Road. Most of these shellfish have long been extinct, and some fossils are more precious and have geological research value. This geological belt extends eastward to the Dinghu and Huadu areas. He said that at that time, the Area around Guangzhou was a bulging ancient land island, while the current Guangxi region was a deep sea at that time.
Do you know: Do you know them?
Brachiopods: Brachiopods are mollusk phylum, marine benthic invertebrates. Brachiopods are similar in appearance to modern shells, but not identical. The shells of brachiopods are divided into dorsal and ventral shells, while bivalves are left and right shells. Brachiopods are distributed from the shallows of the warm sea to the deep seabed, flourishing in the Paleozoic Era, gradually declining with the passage of time, and most of them are now extinct, which can be used as standardized stones to determine the geological age of the stratigraphic.
Sea Lily: Sea lily is an ancient invertebrate that was found everywhere in the ocean hundreds of millions of years ago. In the Paleozoic Carboniferous Period, the number of sea lilies was extremely large and varied. Sea lilies are not plants, but a echinoderm, living in the sea, with many brachiopods, a flower-shaped body, a calcareous shell on the surface, because they look like plants, people have given them the name "sea lilies".
