"We continue to search, and there is one mammoth here, and there must be a second one. It is impossible that only such a mammoth was frozen at that time." With the discovery, Han Peacock's spirit perked up.
"Mark this side, too. There's one down here, and it looks like it's well preserved." Soon Peacock Han made the discovery.
At first, Han Peacock's search direction was mainly downward. But now that he knew how deep the mammoth was buried in the ground, Han Peacock could expand the search area in a targeted manner.
With the first mammoth fossil discovered as the center and radiating outward, the Korean Peacock soon discovered the second and third mammoth fossils. Sure enough, the Yukon River region is an important place for excavation of mammoth fossils.
The main reason why I couldn't find it before was because I didn't look for the right place. But if you find the right place, you can gain something one after another.
"Here, we dug out these tusks." After marking three mammoth fossils in succession, Han Peacock stopped at one place and stopped exaggerating the search area.
Now that a place where mammoths are buried has been discovered, Korean Peacock is not anxious anymore. Some mammoth fossils will definitely be found in this area.
"Dig now?" Huangshan has long wanted to dig out a mammoth tusk and have a look. After all, it is too cold here and activities are warmer.
"Warm up first. The fossil here only has one head. Of course, the two huge tusks on it are still well preserved. The most important thing is that it is not deep from the ground." Han Peacock said with a smile.
The permafrost layer here is two meters deep underground, and the permafrost layer is several hundred meters deep.
For example, the permafrost in the Arctic is more than a kilometer thick, the annual average ground temperature is -15C, and the top surface of the permafrost is close to the ground.
To the south, approaching the southern boundary of continuous frozen soil, the thickness of permafrost decreases to less than 100m. The thickness of the frozen soil layer gradually becomes thinner from high latitudes to low latitudes, and even disappears completely, so this area can only be regarded as permafrost.
of the periphery.
The mammoth head discovered this time is four meters deep underground, that is, two meters below the permafrost layer. This depth is much lower than the mammoth fossils discovered by Han Peacock that were often more than ten meters deep.
It's not that deep.
Han Kongque and his group are all powerful masters who have no place to use their strength. Naturally, no one is afraid of such a depth, not to mention that they will not put in any effort.
Although the permafrost layer was difficult to excavate, Han Peacock mobilized an excavator directly from the chaotic space. In just a few strokes, the permafrost layer was broken open, exposing the huge ivory.
"Okay, okay, let's dig manually next." I didn't expect it to be so simple. Huangshan didn't want the golden demon to continue to control the machine. It felt better to dig out the treasure manually.
With Han Peacock's spiritual observation, they are not afraid of hurting the ivory, so they can dig faster.
It only took half an hour for the two huge tusks to be exposed, and the mammoth's head to be fully revealed.
It has an ivory that is almost two meters long and a skull that is half a meter long. It is really rare to see such a huge creature now.
"So ugly?" Huangshan was a little disappointed after seeing the mammoth tusks.
"So big?" Jin Yao looked at the problem from a different angle.
"Too ugly." Mu Ling also said in disgust.
Although Bing Ning did not speak, it could be seen from the frown on her face that she did not expect these two tusks to be so ugly.
These two ivory tusks are indeed unsightly, slightly gray in color, and because they are in a semi-fossilized state, they look a bit dry and opaque.
However, these two tusks are considered very good among all the excavated mammoth tusks. After all, they can be used, and if they are processed well, the effect is still very good, especially if the skin of the mammoth tusks is preserved.
, will achieve a different effect.
At present, mammoth tooth processing has formed its own unique style. Some mammoth handicrafts will retain the "tooth skin", highlighting a simple and dignified style.
After carefully observing the tooth patterns on it, Han Peacock determined that it was mammoth ivory, not other types of ivory.
The lines with different thicknesses above should be Schiff's lines, and the strong network structure they form is Schiff's structure, as well as Schiff's angles.
Schiff's horns are lines of varying thickness on the cross-section of ivory, forming a strong network structure. This structure is a unique feature of African ivory/Asian ivory and mammoth ivory, commonly known as "tooth pattern".
The size of the Schiffer's angle (the angle formed by the Schiffer's line) near the "tooth skin" can be distinguished.
The average Schiff angle of African ivory and Asian ivory is greater than 115 degrees, and the average Schiff angle of mammoth tusks is less than 90 degrees.
As for the tooth skin, mammoth ivory has a very thick tooth skin, so it will look very primitive after being processed, while the Asian ivory skin is relatively thin.
In appearance, the shape of branched African ivory is crescent-shaped, while the shape of branched mammoth tusks is large and twisted.
The color of ivory has white, yellow, light brown and other tones, the surface is not covered with enamel, the texture is tough and fine, and the luster is soft, so it looks beautiful.
The mammoth ivory has been buried underground for tens of thousands of years. The dentition has been semi-petrified or completely petrified, and its color is slightly gray or even brown. It is a masterpiece of nature without decay, so the Korean peacock has no other luxury.
Mammoth ivory is in a semi-fossil state, dry and opaque, which is very different from the moistness and transparency of ivory, especially the tooth grain, tooth core, etc., which are in obvious contrast.
Mammoth ivory is incomparable to modern ivory. The ivory grows wider toward the outer ring, the texture becomes looser, the ivory is less moist, and the reticulated and herringbone patterns become more obvious.
The closer the ivory is to the tooth core, the less obvious the tooth lines are, the denser the texture, and the better the moistness of the tooth.
The ivory heart is usually made into bracelets and the like, and the scraps from the periphery of the tooth can be made into hand beads. With good blood teeth, you can barely see the tooth lines, and the transparency is so good that it can be seen through natural light.
Therefore, even if there are a lot of mammoth ivory on the market, some people are still unscrupulous enough to poach ivory because ivory products are more beautiful than mammoth ivory fossil products.
The outer skin of ivory is peeled off during processing, so it cannot be seen on the round sculptures and pendants we buy. However, it can be seen on the raw ivory. The black-skinned ivory has good dentition and a shallow mouth, making it the finest ivory.
Since mammoth ivory has been buried in the soil for a long time, it is difficult to distinguish between the outer skin and the inner skin due to petrification. Generally, the skin color of mammoth ivory is obviously darker than that of ivory skin, and the skin of mammoth ivory has no enamel.
When Han Kongque cleaned out the two tusks, their support team also came, not from the outside world, but from the chaotic space.
This time, scientists from the Devil's Island Laboratory came over. They needed to find catkins in order to enter the chaotic space through the ink lotus diagram in the catkins leader's hand.
The arrival of a scientific research team of more than a dozen people made the wasteland lively. Through careful questioning, these scientists determined the objects to be excavated.
There were three complete mammoths discovered by Han Peacock, one of which was slightly damaged and the smallest. These scientists chose the one that was slightly damaged and the smallest to excavate first.
In their words, if it is not handled properly, even if there is a loss, the loss will be minimized.
Even so, the excavation should be done with caution this time. After all, this is a completely frozen mammoth.
If this mammoth is excavated, Han Kongque and others can see what these behemoths that lived on the earth tens of thousands of years ago looked like.
From the fact that this mammoth is so well preserved, it can be analyzed that the mammoth here died in a sudden ice age, so the body was frozen immediately after death, so it did not have time to decay in the future.
And because it has been protected and buried by ice and snow in the cave for thousands of years, it can be completely preserved.
Complete individuals with skin and flesh have also been found in the permafrost in northern Siberia, the Soviet Union. Of course, this area has also been found before, so it is not unusual for Korean peacocks to find several well-preserved mammoths. Therefore, Siberia and
The best mammoth tusks are found in Alaska's permafrost.
Han Kongque also did not expect that when he discovered mammoth fossils for the first time, he found a complete body of a prehistoric mammoth in the permafrost. The most surprising thing was that due to the freezing climate, the body of this mammoth was
The preservation is relatively complete.
Because it was necessary to preserve this mammoth as much as possible, the last moment of excavation was chosen in the coldest early morning, so that the temperature difference between the inside and outside would not be too great.
At this time, the outside temperature has reached more than ten degrees below zero, so we are not afraid that the mammoths that have just been cleaned will be affected. Of course, working at this time will be very uncomfortable for the people working there.
After clearing out the mammoth, they have obtained the eyes, large foot pads, and even internal organs of this young mammoth that is more than 10,000 years old, all of which are intact.
From the perspective of mammoth growth, this can only be regarded as an infant mammoth, and its wounds may have been caused by lions or prehistoric humans.
This mammoth was covered in long, fluffy hairs, which made it easier for them to live in an ice-covered environment. This mammoth died when it was three to four years old.
The most striking thing is that there are two clear wounds on the mammoth's back, as well as several missing bones, including the spine, skull, ribs and pelvic area, but the skull area was found near the corpse.
In addition, after carefully studying the mammoth's wounds, they found that there were long linear incisions from the head to the center of the back, just like the "unusual incision shape" found on the right side of the abdomen. These marks were like a primitive
A serrated tool that remains after cutting.
It is obvious that this kind of slaughtering method cannot be caused by predators such as lions. It is more likely that ancient humans in the Ice Age used saw-like tools when slaughtering mammoths. (~^~)
