Introduction
This world-famous special fossil is found in Chengjiang Hill, Yunnan, about 530 million years, including a lot of lifelike singular fossils, and many preserved Exquisite soft and fossils, they are the direct evidence of Han Wu Ji. Chengjiang bio group is a complete preservation of the early ancient bioal fossil group, covering 16 doors, more than 200 species fossils. On July 1, 2012, Chengjiang fossil is officially included in the World Heritage.
Chengjiang Biological Group reproduces the true appearance of the early ocean organism in the early days, providing extremely precious evidence to reveal the early life evolution of Earth. Chengjiang Biological fossils are stored in delicate mudstones, and the animal's soft limbs are beautifully preserved, and there are three-dimensional preservation. The ancestors of all categories in today's creatures have found. Chengjiang bioquarium is characterized by rare preservation of softomal fossils. It has been discovered that the cultivaty subordinates of Chengjiang biota, algae, sponge animals, causal animals, petron animals, leaves, and artifices, wrist animals, software Animal, arthropod, ratcinous animal, nematode animal, cocci animal, a plum animal, a somatic gantry such as a cordial, some classified position unknown singular groups, mosaic stone and fecal fossils.
These most primitive various types of marine animal software in Chengjiang bioquarium is in good condition, and it is the most old, the most complete multi-category group found in the world. . Vividly reproduce the magnificent landscape and the original characteristics of the current ocean life, and provide precious evidence for the study of early life, evolution, ecology and other theories in the early days. The discovery of Chengjiang Biochemical Fossably has aroused the sensation of the world's scientific community, known as "one of the most amazing discovery of the 20th century".
Distribution range
Chengjiang biota fossil distribution is extensive, located in Chengdong, Chengjiang County, Yuxi City, Yuxi City, Yuxi City, Yuxi City, Yudi City, 6 km of Ham Tianshan, 6 kilometers. 56 km from Kunming, 87 km away from Yuxi City.
Cap Tianshan fossil belt, is tapered, this distribution is 20 kilometers long, 4.5 km wide, the buried depth is 50 meters.
Discovery process
Mid June 1984, from the Hou Xianguang, from the Master of Ancient Biology, Chinese Academy of Sciences, came to the Yushan Mountain in Chengjiang County, Yunnan Province, looking for that once survived in Cambrian High muscle fossils. He has been late every day, climbed through the rugged mountain road, and search for the ancient biological fossils. The stone is two or three tons of weights every day, however, the hard work does not have to wanted to gain, working for more than a week, But both hands are empty, Houxian is not exempting some disappointment.
On 3:00 pm on July 1, Hou Xianguang, which is excavating, and the shoes are inadvertently filled with a loose rock formation, and a piece of strange but saves the complete fossil. , Ecstasy, he judged by the knowledge they had learned, this is a cold invertebrate fossil in the early days. He made persistent efforts. On the same day, he found three important fossils, and later identified that it was discovered that it was Nauro, the blue shrimp and the peak fossil.
is like opening an ancient bio-treated gate. In this day, Houxian Guang has repeatedly discovered the perpetual animal, water mother, worm, and the like ancient fossils. After returning to Nanjing, he worked with Professor Zhang Wentang, and wrote "Nauro in the foundation of Asia", and the animal fossil of Chengjiang is "Chengjiang Biological Group" in the paper.
From July 1, 1984, it was found that Dr. Chengjiang Animal Fossure is now, Houxian Guangguang and his partner - China and foreign geological biologists have conducted a lot of research work, and the basic content of Chengjiang animal group has basically It is clear that there are nearly more than 100 living categories of the ancient times, including algae in the plant, sponge animals in invertebrates, open categories, causal animals, 栉水 maneu, leaf foot , Ciliary chloroform, parel organism, arthropod, Yunnan insects, etc. To accurately explain the traits of these creatures, it is a special researcher. However, we have seen the scientist's ecological restoration map of the Chengjiang animal stone group drawn according to the research results. Immediately attracted the singular shape of these organisms of the ancient times shallow waters.
These creatures are only a few millimeters of size, large tens of millimeters or even larger, they are like a sponge, like a worm, like a jellyfish, like a sea shrimp, like a hat, like a vase, like a flower Like a disc ... is really a strange, beautiful. They showed the singularity of various organisms in shallow sea waters 530 million years ago.
Protective level
Chengjiang bio group is from the world's most discovered area in the world. Not only the bio-hard body tissue is stored, but also preserves a large number of soft bio-fossils, exhibiting a complete Hanwu early marine bio community and ecosystem. On January 14, 2011, "Chengjiang Animal Fossure" was finally named "Chengjiang Fossil" as the final name, officially identified by the State Council as the only item for the Chinese government declared world natural heritage.
On July 1, 2012, at the 36th session of the World Heritage Committee held in St. Petersburg, Russia, Chengjiang fossils successfully passed the vote, officially included in the World Heritage List, became China's first Fossil World Heritage, filled the gap between China's fossil natural heritage.
Found meaning
1, providing ancient biological evidence
The "cold draft outbreak" of the earth's life is here. Chengjiang Biological Group reproduces the true appearance of the early ocean organism in the early days, providing extremely precious evidence to reveal the mystery of Earth's early life evolution. Chengjiang biotonium fossils are stored in delicate mud rocks, and animal soft body is beautifully preserved and saved in three-dimensional. The structural fine energy can be easily revealed in the microscope.
Life diversity is the basic characteristics of all complexities, which is the basic form of life, thus becoming a most concern with the world today. "Hanwu Big Broad" incident occurred from 540 million to 530 million years is the most important event formed by the basic framework of modern diversity. my country's early morning and cold martial arts is not only completely complete, but also is very ancient, and the representative time is very close to the "Han Wu Dawa Broad" incident, in order to reveal the "Han Wu Ji Broad Dream" and in turn This important scientific issue provides a best "window" and rich scientific basis for the origin and evolution of the diversity of human beings.
Scientists have taken more than 130 fossils. Almost all the categories of the current animals and extinct creatures suddenly appeared in the cold murder floor, but the annual formations did not have their ancestral fossils found. Chengjiang bioquarium is characterized by rare preservation of softomal fossils. It has been discovered that the cultivated fossil branch of Chengjiang biotonium, animal, guano animal, leaf fat animal, wrist animal, soft animal, arthropod, etc. The animal door and a singular group of some classified positions. In addition, there are a variety of symbiotic algae. The jellyfish in the animal fossil group filled the blank of the ancient biological research in my country. The discovery of early jellyfish fossils in the early days of the cold is also the first time.
Except for jellyfish, there are sponges, worms, wrist footsteps, abdominal, soft tongue, golden borephics, and other types of arthropod, and its software structure and bone preservation are very complete. And with a variety of kinds, the complete preservation, vividly can be comparable to the world famous Australian night Han Wu Ji, Bourgius Shale, Canada. And this discovery fills an important part of the evolution between Booleans and Eddikara. Although more than 500 million years of vicissitudes, these most primitive various types of marine animal software structures are well-constructed, and there is a very old, lifelike, and is the oldest and most preserved multi-category group group found in the world; Vividly reproduce the original characteristics of the marine life magnificent landscape and the current animals, providing precious evidence for the study of early life, evolution, ecology and other theory.
The discovery of Chengjiang Animal fossimism, causing the sensation of the world's scientific community, known as "one of the most amazing discovery of the 20th century. Chengjiang biotriqué accurately records the historical facts of the early bioabs of Cambrian. Not only The nonlinear sudden evolution of "Han Wu Ji Broadre Dream" provides a scientific facts, and it has produced significant challenges to Darwin gravity evolution.
2, life origin of life
Arthropod is the largest type in the animal industry, but the relationship between arthropical animals and the relationship between various groups, the scientific community is very small. In the past, fossils found, mostly the outer skeleton of arthropods, In order to solve the artificial classification, discuss its evolutionary relationship, the key construction is leg limbs. Precautions of the leg limbs are rarely found in fossils. Therefore, the system classification of the Hanwu arti arts is in a chaotic state.
Through Chengjiang Festival animal research, there is a clear understanding of arthropod classification relationship with the original characteristics. Chengjiang arthropod has a very original body differentiation, such as modern shrimp, about 18 different types of dysfunction, and Chengjiang festival animal only 3 or 4. Fully demonstrates the development of different functional evolution as a long time, the arthropods of arthroplasts exercises.
In the biological group of Chengjiang, the double-criminal arthrost is a variety of pieces, small Around 1mm, the big can reach more than 100mm, many types are saved with perfect soft limbs. The study confirmed that similar shells were wrapped in very different software and limbs. Therefore, their shell flaps can be used as a basis for classification and interrelationships. The shell is a convergence of evolution. The same is a double-petal shell animal, and they can be divided into different superline. Therefore, Chengjiang bioquipment provides valuable evidence for scientists to study early life origin and evolution.
3, Fast evolution evidence
Chengjiang Biological Group showed a variety of animals to appear immediately when the Cambrian broke out, now lives on the earth, almost all of the animal categories, and it is in a very The original grade, only in the later evolution, each of the different groups evolved into a fixed mode. If the number of heads of all insects is the same, the number of primary arthropod groups is quite large. (From 1st to 7). From morphological point of view, the evolution of Wushi Animals in the early cold is much better than now. The new constructor can be generated at one night, the classification unit characteristics The speed of the generated may be as fast as we think.
Darwin pointed out that higher levels of classification is the result of slowly accumulating the evolution of biological type horizontal levels, and reaches the genus , Objective, Outline and Gate level. This does not mean that Darwin is incorrect because of the shackles of scientific conditions at that time, but its theory is not comprehensive. Natural choice is largely a stable choice, this choice It is possible to hamper evolution. In addition, as the situation encountered in the current insects and plants, new or small mutations can be formed by a single or few mutations, and actually hybrids are difficult to produce.
< P> In Cambrian, the new door (such as a wrist dome) through different organs in the growth rate, can be generated by simple conversion, so that the adult individual can save a ancestral larvae filter lifestyle. This process can be formed in hundreds of years or thousands of years. Evidence (mutation) of the biological advanced classification unit provided by Chengjiang Biological Group (mutation) is what we cannot be read in the textbook.4, modifying the history of biological evolution
The older group of the oldest preserved software that is known is the Central Hanwucked Canada Boolean Biological Group, it is better than the cold Wu Shi Hanmu broke out more than 1 million years later. Therefore, the Boolean biotr group of Canada is impossible to point out what the oldest animals on the earth are. We have known the biological and biological community structures generated by Cambrian Bioma.
In modern oceans, 70% of the animal species and individuals are actually composed of soft tissues, so there is little possible possible to form fossils. So, when the Cambrian creature is big, there will be such a large number of soft body animals.
Through Chengjiang fossil research, it is fully able to fix some of the original research error perspectives. Such as animal door large shrimp animals, has more than 100 years of research history, and this animal has been considered to be a huge monster in the past. Chengjiang biotics not only have such animals, but also stored well, and the research has fundamentally changing the original view. The study of the German shale leaves of Boolean, Canada, the scientific community, has always used it as an incredible laky monster. Clarion's similar fossil research, proved that the research results are back, abdominal inverted. If there is no Chengjiang bio group, we will always be a mystery for these animals.

Chinese Academy of Sciences Nanjing Geological Biological Studies The first discovery of Herde Shrimp in the Chengjiang Biological Group was reported on the British "Journallessystematicpalaeontology". These shrimp fossils have a total of six kinds of monoclon, including at least two new species. The discovery of various types of shrimp fossils in Chengjiang Biological Group, indicating that the early prenatal shrimp animals have been highly diversified in the early days of Cambrian, which confirmed the complex food chain and ecosystem similar to the modern ocean in Cambrian. The outbreak is already formed.
Discover two
Han Jian researchers in the early life research team of Northwestern University, cooperated with the UK Cambridge University, and found two older polyprotics in the Yunnan Chengjiang Biological Group. - Ancient sectaria and Chinese female caterpillar. Among them, ancient dishword or a link animal that has been preserved in a known multi-hairy fossil, which has unique significance for the origin of exploration.
Molecular biology studies show that multi-hairy is the most original type in the link animals. Through research, this team found two newly known older polyprotic vendial species in Yunnan Chengjiang Biological fossils, including ancient sectaria and Chinese follicle caterpillar. The most significant feature of the two includes a complete baffle and mush, and a bundled bristles extending from the slats. The most strange thing is that the torso surface of the ancient sewa also has a tabs that are arranged, and the two ribs under small spines. These bone structures are common in modern soft animal doors and the original tentacles.
Thus, they believe that the ancient seafrich should be a link animal that has been preserved in the most primitive characteristics of the known multi-hairy fossils; and the inside of the Chinese fiddier caterpillar has the exterior of the body. Acupuncture, it is likely to be closer to the multi-hairy crown. The research results are titled "China's discovery of the multi-hairy" of the early bones of the cold, "published online" Nature "" Science
