Are human fossils rare? Are fossils valuable?

There are very few fossils of ancient humans, because the number of human beings was still very scarce, and by the time of the progress of civilization in the later period, human beings had begun to bury them, so fossils would not be formed. Pre-human fossils are scarce. Ancient human fossils in China are also relatively abundant, certainly not as many as in Africa.

One of the most famous hominin fossils is Peking Man, which is a representative of Homo erectus in East Asia. However, the age of ancient human fossils in China cannot be compared with that of Africa. The earliest Wushan ape man in China is only 2 million years old.

And Africa's is more than 5 million years old.

Hominin fossils are rare because the formation of fossils requires a certain amount of time and specific geological conditions. Because of the vast territory of China, the number of ancient human fossils is relatively large.

The timing of fossil formation is not fixed and varies depending on geological conditions.

Rare, the living environment and survival ability of human beings determine that the possibility of human fossils is small, and it is not easy to find, you see Lucy more than 3 million years ago, is the only fossil of their kind of Australopithecus.

There are many factors that affect the formation of human fossils, including the time of burial and the burial environment, and other factors. It is one of the important contents of Paleolithic archaeological research and paleoanthropological research. The skull of Peking Man as we know it is a fossil of ancient humans.

Ancient human fossils are more likely to be found in cave sites. So far, due to the insufficient depth and breadth of work, the number of human fossils found worldwide is not large, and the number of specimens at various stages of human evolution is uneven. Last year, it was rated as one of the top ten new archaeological discoveries in Lingjing, Henan Province, and the Paleolithic site of Lingjing, Henan Province, was found about 100,000 years ago.

It takes hundreds of millions of years for fossils to form, and human history is less than 5 million years, so if human fossils are found, it will definitely be a major event that shocks the world and overturns the existing theoretical system of biological evolution.

Not rare, crematoriums are more.

On September 14th, there was a "16,000-year-old human skull fossil" **, which once appeared in the top few of the Weibo hot search list. It's not right to think about it, the cave people in the junior high school history textbooks are about 30,000 years old

It's all laymen. It is impossible for humans to be fossilized when they appeared until now, which means that the earliest humans buried in the ground cannot be fossilized until now.

Fossils take hundreds of millions of years to form! So no!

Probably not, it's just hard to find. ~~

It depends on the age and historical value of the past.

Fossils have value.

Fossils have lived on the earth in a long geological time, and many of the remains of these creatures after death or the traces left by life were buried by the sediment of the time.

In the years that followed, the organic matter in the remains of these organisms was decomposed, and the hard parts such as the shells, bones, branches and leaves, along with the surrounding sediment, were petrified and turned into stone, but their original form and structure remained.

In the same way, the traces left by those creatures when they lived can be preserved in this way. We call the remains and remains of these petrified organisms fossils, and fossils generally take at least hundreds of millions of years to form.

Formation conditions:

1. Organic matter must have hard parts, such as shells, bones, teeth, or woody tissues. However, under very favorable conditions, even very fragile organisms, such as insects or jellyfish, are able to turn into fossils.

2. Creatures must avoid being destroyed immediately after death. If a creature's body parts are crushed, decayed, or severely weathered, this may alter or eliminate the possibility of the organism becoming fossilized.

Fossils have a very high collection value, and have both scientific research and collection value. Collecting fossils not only allows you to understand scientific knowledge such as natural history, but also plays a role in self-cultivation and sentiment.

Fossils are the remains or relics of various organisms in a distant geological and historical period, therefore, fossils can more or less reflect the conditions of organisms and their living environment at that time, and also provide important clues for human beings to understand the history of life and the history of ecological environment changes on the earth. Through the study of fossils, scientists have gained a deeper understanding of the living environment, lifestyle, laws and mechanisms of evolution of paleontology. The study of marginal disciplines such as biostratigraphy, molecular paleontology, paleobiochemistry and paleobionics is also inseparable from paleontological fossils.

It can be seen that all aspects of paleontology and scientific research in some related disciplines are inseparable from paleontological fossils.

Introduction to fossils and their classification:

Fossils are the remains of paleontology, relics or relics that remain in rocks, most commonly bones and shells. Fossils are of great value for the study of ancient topography, landform, climate, and biological development. According to the relevant laws and regulations of the People's Republic of China, fossils belong to the state.

Except for the special approval of the Ministry of Agriculture of the People's Republic of China, the market trading of fossils is illegal, so the fossils have market value.

1: Fossils in the stratum, from the perspective of their preservation characteristics, can be roughly divided into four categories: solid fossils, molded fossils, relic fossils and chemical fossils;

2: Solid fossils refer to fossils that have been preserved almost in whole or in part from the remains of paleontology itself. Under particularly suitable circumstances, the original organisms avoid the oxidation of the air and the corrosion of bacteria, and their hardware and software can be preserved relatively intact without significant changes;

3: Molded fossils are impressions or recasts left by biological remains in the stratum or surrounding rock. One is imprints, the second is impression fossils, and the third is nuclear fossils;

4: Relic fossils refer to the traces and relics of paleontological life activities preserved in rock formations. The most important of the relict fossils are footprints, in addition to arthropod crawling marks, burrowing, drilling, and the latent burrows composed of tongue-shaped mussels living in coastal areas, which can form relic fossils;

5: Chemical fossils refer to the remains of ancient organisms, although some have been destroyed and not preserved, but the organic components of the organisms that make up the organisms are decomposed to form various organic substances such as amino acids, fatty acids, etc., which can still be retained in the rock formation, which is invisible, but it has a certain chemical molecular structure enough to prove the existence of past organisms fossils called chemical fossils.

There are many, many such fossils. In places where there has been no discovery record, such fossils still have a certain scientific research value, and in places where stratigraphic information has been identified, such significance is not great, not to mention that such fossils can be found a lot, so the value is not great. If it is confirmed that it is already a fossil, you may be able to change it to a pack of cigarettes, but you can't change it to a good brand.

Dear hope this answer is helpful to you.

As follows:

Huanglongyu. Huanglongyu is a kind of quartz stone with silica cryptocrystalline texture, also called yellow wax stone.

Aventurine jade. The reason why aventurine jade is also on the list of the top ten worthless jade is because it itself has nothing to do with jade, but it looks like jade and belongs to a quartz ore.

Eighty-three jade. Eighty-three jade is an associated mineral of jadeite, and it is not really jadeite, so it is not valuable.

Peach Blossom Jade. Peach blossom jade is an emerging jade variety, which belongs to a type of quartzite and is a low-end stone.

Rice topaz. Beige topaz is named because the color is the same as yellow rice, and the main component is calcite crystals, which are yellow because of the metallic chromium.

Dragon's Breath. Dragon breath stone is very fantasy from the name alone, and it is also very colorful from the appearance, because it is more like opal, so some merchants use ancient European gimmicks to package.

Chalcedony. Chalcedony, as the name suggests, is the essence of jade. In fact, chalcedony is a kind of quartz stone, which does not belong to jade.

Ice Emerald. When Bingcui first came out, it was said that it was very expensive, and it was regarded as a kind of jadeite full of green ice**, every item was worth a lot, and some loyal fans of jadeite were also amazed by its transparent texture and shining full green, but the essence of Bingcui is that glass is not worth so much money.

Emperor Stone. Emperor stone is very kingly from the name, but in fact, it belongs to the yellow wax stone class, which is a relatively cheap ore.

Kava stone. Kava stone, also known as Xinjiang Xiuyu, is a stone used to imitate nephrite, which is a fossilized wood, and looks more like jade.

In fact, humans can also become fossils, as early as 50,000 years ago there were modern human fossils, and the history of ancient human fossils before that was even older. Therefore, there is a certain probability that people will become fossils after death.

The remains, relics or traces left by organisms of animals or plants belonging to paleogeological ages preserved in the earth's crust are called fossils. Animal fossils include "fleshy fossils" and "bone fossils". Due to glacial movements, crustal changes and other reasons, the earth's organisms were quickly buried underground, and after hundreds of millions of years of evolution, the biological hardware part was preserved.

However, the possibility of the evolution of the fleshy soft tissues (including ears and internal organs) into fossils is very small, and it is easy to be corroded and dissolved by microorganisms in the natural environment, so it is difficult to form solid flesh fossils.

The "ear" fossil discovered by scholar Huang Jinxiang makes us clearly understand that there are indeed "meat fossils" on the earth, which is a major discovery in the history of human natural science.

1. Squashed Jurassic spider fossils.

This is the best-preserved spider fossil. It comes from China and dates back to the Middle Jurassic period 100 million years ago. The scientific name of this spider is Eoplectreurys Gertschi.

According to paleontologists, the spider fossil is even about 100 million years older than the only two other known specimens of older spiders, and the details are clearer. Spider fossils are very rare due to their fragile bodies and difficult to preserve.

2. Prehistoric python fossils that can devour dinosaurs.

Paleontologists have discovered a 67-million-year-old fossil of a giant python. The python was coiled next to a pile of dinosaur eggs, and there was a baby dinosaur that had just hatched in the python encirclement.

3. Fossilized crocodile dung.

Fossil dung can reveal information about the food and behavior of ancient animals. However, the fossil in this image appears rather bizarre. The fossil was found beneath a sandy beach on the west coast of Chesapeake Bay in the United States.

4. Source Australopithecus fossils.

With the help of Google Earth, scientists have found two fossilized primate skeletons in South Africa that are 1.9 million years old. This discovery adds a new member to the primate family. Known as the source Australopithecus, this primate has long legs and a nose that protrudes forward, as well as extra-long forearms and flexible feet.

5. Forgotten prehistoric giant fish fossils.

These fossils were initially ignored and forgotten because of miscalculations. Later, scientists rediscovered the fossils in the museum and judged them to be two newly discovered species. They are the fossils of two prehistoric giant fish that lived in the ocean about 100 million years ago.

After hundreds of millions of years to become a fossil, due to the erosion of geology, it was exposed to the ground and discovered.

Fossil Finds:

How to know if there are fossils in a stone requires manual judgment. For example, what strata, what rocks, and what age corresponds; whether there may be fossils in it; If so, what fossils may be. For example, the Permian, Triassic, Jurassic, Cretaceous, etc., their respective geological characteristics are not the same, and experienced people can judge them.

In addition, most fossils are found in production and life rather than professionals, for example, if a part of an insect is exposed on a rock, then there may be other insect fossils buried in the stone, which require further processing.

Handling of fossils:

Fossils are collected from the field and processed in-house, which is important for both material research and teaching. There are a variety of treatments, and most fossils need to be repaired to obtain clearly decorated specimens or clear internal structures. Repair of fossils,
