There have been countless creatures living on the earth, and the remains or traces of these creatures after death are quickly buried, and the organic matter in them is decomposed, and the hard shells, bones, etc. are petrified together with the surrounding sediments and become fossils, still retaining their original form and structure. Next, let's walk into the fossil series together.
Chengjiang biota
The Chengjiang biota is located near the Maotian Mountain in Chengjiang, Yunnan, China, and the output strata is the yellow-green silt shale of the Yuqushan section of the Lower Cambrian Bamboo Temple Formation in Yunnan, which is a well-preserved early Cambrian paleontological fossil group.

Carey Biota
The Kaili biota is located in Kaili City, Qiandongnan Prefecture, Guizhou, and belongs to the early Middle Cambrian period, 520 million years ago.

Guanling biota
01
Ichthyosaurs are representative fossils of the Guanling biota. Ichthyosaurs are large marine reptiles that resemble fish and dolphins. It predates dinosaurs, and ichthyosaurs appeared about 250 million years ago. Unfortunately, they suffered a mass extinction about 90 million years ago and disappeared from the earth.

Sea lilies are a kind of echinoderms that first appeared in the Carboniferous Period, with multiple brachiopods, a flower-shaped body, and a limestone shell on the surface, because they look like plants, people gave them the name of sea lilies.

Rehe biota
The Rehe biota lived in the Late Mesozoic Era, and the Western Liaoning region of China is a classic area for studying the Rehe biota. It preserves a large number of exquisite fossils, including dinosaurs, birds, pterosaurs, etc., and is known as "one of the most important paleontological discoveries in the world in the 20th century", a world-class fossil treasure trove, Pompeii in the Mesozoic Era.

and political biota
In the Cenozoic Era, mammals dominated the earth, especially with placental evolutionary radiation. The Paleogene is characterized by the flourishing of ancient types such as ungulates and carnivorous; the Neogene is a period of great development of ungulates and elephants, and the ancestors of modern mammals have basically appeared; the Quaternary is characterized by the emergence of modern mammalian species.

Shanwang biota
The Shanwang biota is a biota composed of a series of paleontologists found in Shanwang Village, Linqu County, Shandong Province, China. Formed 18 million years ago, shanwang biota is the only stratigraphic paleontological fossil remain in China, rare in the world, with complete preservation, complete categories, irreplaceable and important scientific value in the Miocene.

trilobite
The trilobites have a flattened body, covered with strong dorsal carapace, and the ventral side is a soft peritoneum and appendages. The dorsal carapace is two dorsal grooves, which are divided longitudinally into an axis leaf and two rib lobes, hence the name trilobite.
Ammonite
Ammonite is an umbrella term for a group of extinct marine life that lived from the Middle Ordovician to the Late Cretaceous, so named because of the often chrysanthemum-like lines on its surface.

Owl head shell
Owl head shell, ancient invertebrate. A genus of brachiopods. The shell lobes are large, convex, and nearly rounded. The shell beak of the abdominal shell is curved like a hook and resembles an owl's beak. The shell surface is smooth and has no finish. It lived in the Middle Devonian.
Silicified wood
Silicified wood is a true wood fossil, a tree fossil that was replaced by silica in groundwater after trees were quickly buried underground millions of years or earlier, and it retains the wooden structure and texture of trees.
Dinosaur egg fossils
Dinosaur egg fossils are the reproductive products of dinosaurs that can be passed down from generation to generation. Dinosaur egg fossils vary in size, with small diameters of about 3 cm and large diameters of up to 56 cm. Egg fossils are usually ovate in shape, with a few being oblong, oval and olive-shaped. The most prized variety of dinosaur eggs is the dinosaur egg containing embryos.

Fossils, which have evolved over thousands and hundreds of millions of years, are the best witnesses of the history of the earth, leading us to explore the mysterious prehistoric world together.
