A 20 million year old fossil tree was found in Greece, but why are its branches still intact?

It can only be said that this is a gift from nature to human beings: fossil trees are a kind of biological fossils, which can be formed as long as they reach certain geological and climatic conditionsThe branches are well preserved, indicating that they meet at least the following three points: 1. The tree was buried without injuring the branches; 2. The petrochemical process is rapid and thorough, and the branch tip part does not decay; 3. In the long process of geological change, there is no major crustal movement or other damage

1. The formation principle of fossil trees

The formation of fossil trees has its own peculiarities, isTens of millions of years ago, after the trees were quickly buried underground due to various reasons such as ** and volcanoes, the chemicals around the trees such as silica, magnesium sulfide, calcium carbonate, etc., entered the interior of the tree under the action of groundwater, and through the dual action of pressure and temperature, silicon and other chemicals produced crystallization and other reactions。In the process, the original wood composition is replaced, and only the wood structure and texture are retained, forming a fossil treeBecause of this, fossilized wood is also known as "petrified wood."

2. The rarity of the Greek fossil tree

The recently discovered fossil tree in Greece was unearthed on the island of volcano, which has about 10,000 hectares of petrified forest – not specifically excavated, but accidentally discovered during road construction and covered in a thick layer of volcanic ashThe tree is about 19 meters tall, and the rarest thing is that the roots and branches are clear and intactIt's amazing. Finally, it was transported by people with special clips and metal platforms.

Zuros, a professor at the Natural History Museum of the Petrified Forest on the island of, saidThis is the first time since 1995 that such a well-preserved fossil tree has been discovered, and through research, it will be possible to determine which plant it belongs to。At the same time, it was also saidDuring this excavation, various trees were found on the island from 17 million to 20 million years ago, and with the help of these, it was possible to reconstruct the ecosystem that existed during that period

3. Fossil tree resources in China

There are many places in the world where there are fossil trees, and the distribution in China is also relatively wide, and there are many varieties。In fact, there have been records of fossil trees in China for a long time, for example, the inscription of the famous Tang Dynasty poet Tortoise Meng's "Two Legacy Poems" clearly states that "Zhongrao ancient pines are often turned into stones", and there are similar records in Shen Kuo's "Mengxi Bi Tan" in the Northern Song Dynasty.

In recent years,Chinese researchers have found silicified preserved plant fern fossils in the Tacheng area of Xinjiang, which is the earliest petrified wood so far。In addition to Xinjiang, Yanqing in Beijing and Xinchang in Zhejiang have also been discovered, and the "Petrified Wood National Geopark" has been established. Among them,A number of petrified wood were collected in the Xinjiang Ancient Ecological Park, each with a diameter of about 1 meter to 4 meters, and the longest was 56 meters, which was longer than the 37-meter petrified wood in Yellowstone Park in the United States, which had been declared a Guinness Book of Records

Because fossils have to be buried in the ground for thousands of years, isolated from the air, they can slowly form fossils, and because all the conditions are in place, the branches can be preserved.

Maybe it's because it's been air-dried, and the things that will rot inside are taken out so that they don't rot, and the body stays here.

Because it's been a long time, think about it, can you keep a thing for two thousand years, let alone two thousand years, twenty years is not necessarily.

First of all, the objects from 20 million years ago are too long, and some of them have been crushed into fragments after many years of geological changes, and it is difficult to preserve them intact until now.

The main thing is that this fossil tree, which is 20 million years old, is well preserved, the branches and roots are clearly visible, and now it has reappeared, and it is very proud to be a tree, which is very rare.

It should be said that it is very rare, because it is very difficult for such a fossil tree to be preserved to this day.

A 20-million-year-old fossil tree was found in Greece, about 19 meters long, with intact branches and roots, and clearly visible lines.

It is a fossil that has never been seen in the area so far, and the petrified tree is a type of fossil in which the organic matter of the tree has been replaced by minerals such as silicate during geological evolution, but the original structure of the wood has been preserved to the microscopic level. Due to the complex structure of the surrounding crustal plates, volcanoes, and frequent forests, a unique petrified forest landscape was formed during the earth's evolution 20 million years ago, providing humans with a wealth of information about the composition, characteristics and climatic conditions of ancient flora.

It should be said that it is particularly rare, because fossils themselves are very uncommon things, let alone a tree.

Greek scientists recently discovered a rare fossil tree on the volcanic island of, whose branches and roots are still intact after 20 million years. During the excavations, various trees were found on the island of from 17 million to 20 million years ago, a unique discovery that allowed one to reconstruct the ecosystem that existed during that period.

It is particularly rare, and it is estimated that this is the first discovery of such a fossil tree.

1. Magical nature

Greek scientists in the field of chemistry have found a rare fossil tree on a volcanic island called, this fossil tree sounds ordinary to me, but it is not ordinary, in addition to its long time--- more than 20 million years ago, what is even more amazing is that although it has gone through so many years of geology, climate, environment, and great changes in the earth, this tree still seems to be not lacking in branches and leaves, and it is very intact and preserved.

Travel back in time and space to imagine how many ancient fossil trees are buried on this volcanic island 20 million years ago, when the trees on the island were repeatedly covered and piled up by the hot lava from the eruptions. More than 20 million years ago, the island thrived with thriving life, with tens of thousands of hectares of forests covered by rolling trees.

Perhaps more than 20 million years later, we will never be able to restore it to its original appearance through technical means, but the miraculous Creator has left us this 19-meter-long complete fossil tree, which has played a vital role in our study of ancient ecosystems. Another unexpected discovery is that in addition to this complete fossil tree, some other tree and animal fossils have been found in the nearby area, which is really an unexpected harvest!

Second, the cause of formation

So, how did this huge fossil tree, which has been preserved so intact after so many years, come to be? In the process of decay, groundwater or other water seeps into the tree, and a part of the inorganic salts dissolved in the water will slowly precipitate on the part of the organism that is not easy to be corrupted with the evaporation of water, accumulating into a layer of crystal shells, which will slowly thicken and fill the original position of the entire tree, and become fossils. Plants have cell walls, so it's easier to produce whole fossils.

Third, experts said

Fossil experts are thrilled that this is the best-preserved tree we have ever excavated since it was developed in 1995. We are thrilled to discover such a huge and well-preserved fossil tree, and in the process of excavating this huge fossil tree, we have also discovered a variety of trees that existed in other years, which is a huge help for studying the ecosystem 20 million years ago.

Because of its location, it is deserted, no one destroys it, and it has a very special tree species.

In this episode, let's take a closer look at the archaeological discoveries of paleontology and ancient ruins, what methods did scientists use to identify their years?

Yes, according to Reuters,Greek scientists recently discovered a rare fossil tree on the volcanic island ofThe branches and roots of the tree are still intact after 20 million years.

The tree was discovered during road construction near an ancient forest on the island of, which had been petrified millions of years ago and had been transported out with a special type of splint and metal platform.

Nikos Zouros, a professor at the Natural History Museum of the Petrified Forest on the island of, said it was the first time since excavations began in 1995 that such a well-preserved fossil tree had been found, with its branches and roots intact.

The discovery of a 20-million-year-old fossil tree in Greece is a huge discovery for archaeology. There may be many archaeologically important clues on ancient trees more than 2,000 years ago, because there may be many ancient genes on trees more than 20 million years ago. Although the ancient tree has lost its life, there may still be some genetic material in the cells.

As a result, new discoveries may be made about many of the problems. There may be substantial evidence for both climate change and the eye of life, so the study of this ancient tree may take the study of human biology to a new levelArchaeological materials such as fossils are very rare, so it is especially difficult to find fossil valley books that are more than 20 million years old. <>

It is not easy to excavate this fossil in Greece because it is very difficult to preserve the fossil. Many fossils contain the remains of living beings, but since many of them were directly decomposed by related fungi and bacteria in ancient times, many fossils have not been able to survive to modern times. Being able to see fossil trees that are more than 20 million years old is an important breakthrough in the archaeological community.

As we all know, the vitality and longevity of trees are very strong. A single tree may be able to live for thousands of years. Therefore, for this discovery, we were able to do a better study of ancient trees.

Archaeological discoveries can also confirm many historical problems. This is because there are many historical accounts that do not correspond to the landscape we see in modern times. <>

Therefore, the development of archaeology can promote the progress of the biological and historical worlds, because the conclusions drawn from archaeology provide an important basis for many historical speculations and historical speculations. It is likely that we can deduce the cause of the extinction of the species from the fossil valley book more than 20 million years ago. At the same time, the old tree will still retain its previous genetic material.

It is likely that this genetic material will be able to be studied to draw relevant conclusions. The study of genetic material in biology can better confirm many problems in the evolution of species. By comparing the same elements in the genetic material, it is possible to better determine the evolutionary order of the species.

Therefore, Greece** should have taken good care of this fossil when it discovered this fossil phenomenon. And the fossil needs to be studied by relevant researchers. This discovery is a breakthrough for the world's archaeological community, so it is even more necessary to protect these archaeological discoveries.

It's a new discovery. This fossil tree from 20 million years ago is still well preserved and will bring some new ideas to archaeology.

The 20 million-year-old fossil trees excavated from Greece should be very different from the current trees, and the study of these fossil trees can be used to justify our contemporary evolutionary theory.

I think this discovery is still very valuable, and the tree species from so many years ago are really rare now.

I believe that the discovery of fossil trees is very important for the study of the ancient history of Greece.

The discovery of this fossil tree is actually very meaningful for the study of some history, and it is possible to judge some of the circumstances at that time.

According to Reuters, Greek scientists have been in the market recentlyVolcanic IslandA rare fossil tree was discovered, with branches and roots still intact after 20 million years.

The fossil tree, which was about 19 meters long, was covered in a thick layer of volcanic ash after it fell. A large number of fruit tree leaves and animal bones were also found at the same site.

"During the excavations, a variety of trees were found on the island of from 17 million to 20 million years ago, and we can reconstruct the ecosystem that existed during that period," Zuros said. ”
