Biology or stone? Don't throw these stones when you see them on the mountain! Have a great influence

There are countless creatures living on the earth. The remains or traces of these creatures are buried soon after their death, and the organic matter in them is completely decomposed. Hard shells and bones, together with the surrounding sediments, have become fossils through fossilization, still retaining the original shape and structure. Next, let's go into the fossil series.

chengjiang biota

Chengjiang Biota is located near Maotianshan Mountain in Chengjiang, Yunnan, China, and the occurrence stratum is yellow-green silty shale in Yushan section of Lower Cambrian in Yunnan, which is a well-preserved early Cambrian paleontological fossil group.

Kaili biota

Kaili Biota, located in Kaili City, Qiandongnan Prefecture, Guizhou Province, belongs to marine life in the early Middle Cambrian, dating back 520 million years.

guanling biota

0 1

Ichthyosaurus is a representative fossil of Guanling biota. Ichthyosaur is a large marine reptile similar to fish and dolphins. It appeared before dinosaurs, and there were ichthyosaurs about 250 million years ago. Unfortunately, about 90 million years ago, they suffered a mass extinction and disappeared from the earth.

Sea lilies are echinoderms that began in the Carboniferous. It has many brachiopods, a flower-shaped body and a limestone shell on the surface. Because it looks like a plant, people named it sea lily.

jehol biota

The Jehol biota lived in the late Mesozoic, and the western part of China is a classic area for studying the Jehol biota. A large number of exquisite fossils are preserved here, including dinosaurs, birds and pterosaurs. Known as "one of the most important paleontological discoveries in the world in the 20th century", it is a world-class treasure house of fossils and the Mesozoic Pompeii.

Hezheng biota

In the Cenozoic era, mammals ruled the earth, especially those with placenta. Paleogene is characterized by the prosperity of ancient types such as ungulates and carnivores; Neogene is the great development period of cloven-hoofed animals and elephants, and the ancestors of modern mammals have basically appeared; The Quaternary is characterized by the emergence of modern mammalian genera and species.

shanwang biota

Shanwang Biota is a set of paleontology found in Shanwang Village, Linqu County, Shandong Province, China. Shanwang Biota, which was formed 654.38+0.8 million years ago, is the only well-preserved Miocene stratigraphic fossil relic in China and has irreplaceable scientific value.

trilobite

Trilobites have a flat body covered with a solid carapace and a soft peritoneum and appendages in the abdomen. The carapace is longitudinally divided into two dorsal grooves, one axial lobe and two costal lobes, hence the name trilobite.

ammonite

Chrysanthemum stone is a group of extinct marine life, which lived from the Middle Ordovician to the late Cretaceous, and was named because its surface usually has lines similar to chrysanthemums.

Naked corn borer

Corn borer, an ancient invertebrate. A genus of brachiopods. Shell petals are large and convex, nearly round. The beak of the abdominal shell is bent into a hook and shaped like the beak of an owl. The surface of the shell is smooth without decorative patterns. Living in the middle Devonian.

Silicified wood

Silicified wood is a real wood fossil, which was quickly buried underground millions of years ago and replaced by silicon dioxide in groundwater. It retains the wood structure and texture of trees.

dinosaur egg

Dinosaur eggs are the reproductive products of dinosaurs and can be passed down to the next generation. The size of dinosaur eggs varies greatly, with a small diameter of about 3cm and a large diameter of 56cm. Egg fossils are usually oval, and a few are oval, oval and olive. The most precious variety of dinosaur eggs is dinosaur eggs with embryos.
