What's hidden in this?

Han Zhou was curious.

Han Zhou couldn't help but think of the famous movie "Jurassic Park".

A scientist named Hammond used the dinosaur blood in the body of a prehistoric mosquito condensed in amber to extract the genetic genes of the dinosaurs, resurrecting the prehistoric behemoth that had been extinct for 65 million years, making the entire Isla Nublar a paradise for dinosaurs, that is, "Jurassic Park".

The film is just "science fiction" and doesn't have to be taken seriously.

Because even amber, which claims to be able to seal time, cannot withstand the erosion of 65 million years.

Even if you can really find a mosquito in amber that sucks dinosaur blood, the genetic sequence in the blood has long been damaged due to age. It's a mess of scum.

Not to mention dinosaur blood, even if the bone marrow of a dinosaur is sealed, it can't be cloned.

So the paleontology in amber is like fossils, and it is mainly the form that is retained.

Of course, the form of amber preservation will be more realistic and lifelike. Some feathers, proteins, etc., which are not so old, can also extract certain amino acids, genetic materials, etc.

Very valuable for research.

The famous geohistorian, Xing Lida, became famous by studying the paleontology in amber. (He mainly studied amber and dinosaur tracks)

This person single-handedly pulled the global ranking of China University of Geosciences to the top 80.

Why is it so exaggerated......

Because he alone posted almost 200 SCI articles.

The so-called SCI, or Science Citation Index, is a kind of discrete law theory based on Bradford's literature, and based on the theory of discrete law in Garfield's literature. Based on the citation analysis theory, through the statistics of the citation frequency of papers, the academic journals and scientific research achievements are evaluated in a multi-faceted way, so as to judge the performance of a country's or region, scientific research units and individuals, and reflect their international academic level.

SCI is an internationally recognized scientific and technological literature retrieval tool worthy of reference.

Publishing SCI papers is the only way to enter the high-end academic community.

I often send one or two articles to graduate with a master's degree. And Xing Lida posted 200 articles alone, which is really terrifying. Not to mention that there are also papers from the top international journal "Science".

Xing Lida's birthplace is Tengchong, a border city in China, adjacent to Kachin State in Myanmar, and an important distribution center of Burmese amber. Xing Lida often comes here to look for amber.

He has found countless rare ancient creatures in amber, which together can be called a small zoo:

Freshly hatched primitive birds, feathered dinosaur tails, lizards, frogs, snakes, snails, and a wide variety of insects...... Just as a 19th-century biologist collected species in the abundant and inaccessible rainforests, he used amber from Myanmar's border to depict the details of tropical forest habitats 100 million years ago.

In Xing Lida's article, the vertebrates of the Cretaceous period are enough to fill an ecological tank. For example, the study published in Science Advances found a young snake with 97 vertebrae preserved in amber, the study published in Science Reports showed that there were frogs about 2 centimeters in size in amber, and the most famous study, published in Current Biology, found a feathered dinosaur tail in amber with hemoglobin remaining.

In addition to Xing Lida, other scientists are also stepping up research on amber. In 2018 alone, scientists discovered 321 well-preserved new paleontological species in Burmese amber, a year that already accounts for a quarter of the total number of discoveries (1,195) so far. Some say that the paleobiodiversity found in Burmese amber may be greater than the number of dinosaurs found in previous fossil discoveries combined. The paleontology preserved in amber sheds light on how creatures lived at that time and adapted to arboreal life. These findings could provide a genetic and ecological basis for the formation of modern ecosystems.

About why Xing Lida is so successful.

In fact, in essence, it is not because of the high level of his research, but because he has organized an efficient amber trading network in Tengchong and Myitkyina.

Teach the locals how to look at the claws inside the wings of Cretaceous birds and count the number of toes so that they can tell if it is a lizard or a dinosaur. If he gets some gossip, he will immediately send the photos to the relevant experts, and if it is confirmed that the scientific value of the specimens is indeed worthy of the high price tag, he will decide to buy them.

In this way, when I found traces of paleontology in an amber, I sent a paper.

Find another one, and send another paper.

Find another one, post another one.

......

There is no shortage of children and grandchildren.

You don't need a particularly high level of research to publish this type of paper. Describe the pattern, follow up with the tree, name the importance of the discovery, and the number of words.

It's not to belittle Professor Xing. That's exactly what it is.

If it is a particularly precious amber fossil, it can be published in the top issue. If it's an ordinary fossil, send an ordinary SCI irrigation.

Therefore, some people said that his research is basically based on simple descriptions of fossils, and there are few systematic research results.

This is also true.

This year, a paper by Xing Lida entitled "The World's Smallest Dinosaur (Bird)" was published in Nature and caused a sensation.

But it was quickly questioned by many scholars that it was actually a lizard, not a dinosaur (bird).

In the end, Xing Lida's team "retracted". said that it was a retraction, but it was actually a forced rejection.

Dinosaurs belong to the order Ornithischian and Lizards of the class of reptiles, and lizards belong to the suborder of lizards of the class of reptiles. There is a clear difference between the two morphologically.

And according to the current scientific definition, the so-called dinosaurs are-

"The nearest common ancestor of the sparrow and triceratops and all their descendants".

That said, sparrows are also dinosaurs.

All birds are dinosaurs.

The chickens, ducks and geese you eat every day are dinosaurs.

The goose down (though often duck down) in the down jacket you wear is dinosaur fur.

Dinosaurs, all around us.

Han Zhou said: "Lao Zhao, is there a place to process amber nearby?" These rough amber stones need to be processed to see the doorway inside. ”

Lao Zhao said: "Mr. Han, let's go back to China directly and go to Tengchong." I know a couple of amber processors there, all good brothers who can help you with the processing. ”

Han Zhou said: "Okay." ”

The two drove directly into customs.

Came to Tengchong.

Tengchong belongs to Yunnan Province and is a county-level city managed by Baoshan, located in the southwest of Yunnan Province.

Tengchong in the famous population "Heihe Tengchong Line" refers to this place. Heihe is the city of Heilongjiang.

Pull a line from Heihe to Tengchong. The southeastern region on the right, which accounts for about 43% of the country's land area, is home to about 94% of the country's population.

On the left, about 6% of the country's population lives in the northwestern region, which accounts for about 57% of the country's land area.
