"Titanoboa also lived on land, but it could also go to the sea. Therefore, this is probably the junction of land and sea, so it is understandable that Iguanodon appears on the shore."
"Is it possible that this isn't an Iguanodon at all?"
"It's unlikely. You see, these smaller Iguanodon fossils seem to be bipeds. They stand upright and drag their tails on the ground, acting as the third fulcrum of the tripod. But these huge ones,
It was on all fours, so it must be an Iguanodon, because as the Iguanodon grew older and gained weight, it would more often adopt a quadrupedal gait.
The arms of juvenile Iguanodon are shorter than those of adults, about 60% of the length of the hind limbs, while the length of the forelimbs of the adult is 70% of the hind limbs. Based on the fossilized footprints of the Iguanodon, as well as the structure of the hands and arms of the Iguanodon, we can
It is inferred that when Iguanodon adopts a quadrupedal gait, the three hoof-like fingers in the middle can support the weight.
The hind feet of Iguanodon were quite long, with three toes on them. They would walk like digitigrade animals, using their fingers and claws to walk. Therefore, the maximum speed of Iguanodon running on two legs was estimated to be 24 kilometers per hour.
But they couldn’t run fast using a quadrupedal gait. The dinosaur fossils here are similar to the Iguanodon skeleton fossils in Bernisat, Belgium, so they must be Iguanodon.”
Iguanodon is easy to identify. After all, since 1878, Iguanodon skeleton fossils have been continuously discovered in all continents of the world. The complete skeleton fossils have become the basis for scientists to reproduce Iguanodon.
"It would be great if there had been an earthquake, landslide or volcanic eruption. In this case, the dinosaur fossils here would be very rich." Cao Meili said with a hopeful look on her face.
No matter which country you are in, archeology is not popular and does not receive much attention. If you are in China, if you learn some appraisal knowledge, you can become an expert. Appraise porcelain, or simply search for treasures yourself.
In the United States, studying archeology is not the same thing.
Archeology is only one of the small branches of science, science is only one of the branches of academics, academics is only a part of culture, and culture is only a part of life...
Archaeological research is only an insignificant part of life. When others earn one day as much as you earn in one month, and one year earns more than your whole life, you may not have much choice.
Therefore, there are not many people studying archeology in the United States. Of course, this is only a relative term. If we talk about schools that offer archeology majors, there are still many schools in the United States. Even some famous schools have this major, but this major
Not many graduates do archaeology after completing their studies.
The group of people around Han Kongque are definitely the best among them, because this is their interest.
If this were not the case, they would not be able to bear the loneliness and would have changed careers long ago.
It was their opportunity to meet a big boss who asked them to do archaeological excavations. That's why Cao Meili hoped that there had been a natural disaster here. Only in this way, more dinosaur fossils would be preserved here.
Dinosaurs have lived on the earth for about 160 million years. If their bones could be preserved as fossils after their death, the earth would be covered by a thick layer of dinosaur bones today.
However, it is actually impossible. Only a very small number of dinosaurs among them can retain their bones to this day.
After the death of dinosaurs, in most cases, their bodies were exposed to the wilderness, decomposed, or eaten by animals, and finally turned into nothing.
A small number of corpses will be carried by running water to rivers and lakes and deposited. During the transportation process, the corpses will be severely damaged, and the final fossils will naturally become fragments. Therefore, complete dinosaur fossils are very rare.
Only in rare cases can dinosaur remains be quickly buried by sediments in situ, and then a complete skeleton fossil can be preserved.
This situation is often related to some kind of unexpected event, such as earthquake, flood, rock collapse, sinking into soft sediment, or slipping into a cave.
The Iguanodon skeleton fossils in Bernisat, Belgium, were quickly buried and preserved in the sudden incident.
After the remains of the dinosaur were buried in sediments, the muscles, internal organs, skin and horny parts would slowly decay and decompose. The remaining bones were gradually replaced by minerals in the groundwater, petrified, and became today's fossils.
Apparently there was an emergency here, so many dinosaurs were buried in an instant, and they became what they are now.
Now that the fossils have been discovered, the next step is to use various tools to clean, excavate, and bond and reinforce them in a timely manner, and finally fully expose the fossils.
For complete and smaller fossils, they first wrapped the fossils layer by layer with thin and tough wet paper, and then wrapped them layer by layer with plaster and bandages for reinforcement.
For fragile and large fossils, they dug a deep trench around the fossil, cleared away the gravel and sand in the trench, and then wrapped the top and sides of the fossil with gypsum and other materials until the gypsum had completely solidified and dried.
, we started to clean up the surrounding rock under the fossil, hollowing it out to gradually separate it from the rock.
At the appropriate time, turn it over, clean it slightly, wrap it all with plaster and other materials, take safety measures, and prepare to transport it back to the research institute or museum.
There is no museum for Korean peacocks yet, so we can only build some simple houses to preserve them.
Like the separated marine giant scorpion, it is very easy to handle because it is well preserved. Now Cao Meili and the others only need to use tools to peel off the rock to make the fossils stand out, and bond them in time to strengthen the fossils. At this time, the marine giant scorpion fossil with a complete skeleton is
It can be studied and exhibited.
For large fossils, the bones need to be disassembled piece by piece and put together one by one according to the state in which it was alive, and steel or plastic steel brackets are used to make it stand up.
After the skeleton was assembled, paleontologists restored it based on Cuvier's organ-related theories and the discovered materials.
In order to provide exhibition and research in various places without damaging the fragile fossils, they also need to make an exact model of the fossils.
It can be said that the work after discovering dinosaur fossils is extremely tedious and of course very boring.
The main work now is cleaning and excavation. During this process, Han Peacock also gave guidance from time to time to avoid damage to the fossils inside because he could not clearly see the situation inside the rock.
"Be careful here, there seems to be something unusual inside." Han Kongque grabbed a white boy who was cleaning up the cover.
"Abnormal? This is the bottom, and these Iguanodons are very complete. It is unlikely that there are fragments. Could it be dinosaur footprints?" The white guy's name is Andal, who has the same name as a provincial governor in the Philippines. He heard about it because his grandfather once
He was stationed in the Philippines, so he was given such a name.
Andal is very strong, so he does hard work, such as digging and cleaning rocks, so Han Peacock communicates with him more often, and every time Han Peacock gives him advice, something will be discovered, so Andal does not doubt Han Peacock.
judge.
Han Peacock discovered something strange here. The reason why it felt strange was that it was a nest of round stones. In this case, it was very likely that it was a dinosaur egg, and it was very likely that it was a fossilized conjoined dinosaur egg.
"It's always right to be careful." Han Peacock said with a smile.
Andal looked puzzled, but he still slowed down and became much less powerful. In the end, he simply used a small chisel to slowly clean up the rocks below.
"Huh? Is this a dinosaur egg fossil?" Andal likes archeology. Being able to participate in dinosaur fossil archeology proves that he is very interested in this aspect, so he can recognize the dinosaur egg fossil at once.
"It should be a dinosaur egg fossil. After all, there are many iguanodons here." Han Peacock said with a smile.
It seems that there is no loss this time. You must know that the value of dinosaur eggs is not low.
"Is it really a dinosaur fossil?" Cao Meili asked with surprise on her face.
"How come you are always there wherever new discoveries are made?" Andal muttered.
Every time he made a new discovery under Han Kongque's reminder, he would be taken over by Cao Meili as soon as possible.
"You idiot, what should you do if you hurt these dinosaur eggs with your clumsiness? I can't even afford to sell you." Cao Meili said with a smile.
"I will be careful, don't I know this is something worth millions?" Andal did not want to give up the current excavation work.
"Okay, dig carefully from here. If it is really a dinosaur egg fossil, I think Boss Han will give us a bonus." Cao Meili said with a smile.
Dinosaurs are egg-laying creatures. In addition to the fossilized skeletons left behind when they became extinct, the undamaged dinosaur eggs have become important materials for archaeologists to study this ancient life. They are also an important way for modern humans to explore past history.
one.
The mysterious life and culture wrapped in oval fossils have very high scientific value, ornamental value, and collection value for now, so the current price is very expensive.
Dinosaur egg fossils are very precious paleontological fossils. They were first discovered in the Cretaceous strata in Provence, southern France, in 1869. Since there are not many dinosaur egg fossils found worldwide.
What you see are usually the calcium shells of eggs. It is rare to find eggs containing certain dinosaur embryo fossils. It is difficult to judge which type of dinosaur the egg fossils found were produced by.
Therefore, for a long period of time, the research on dinosaur egg fossils did not make important progress.
According to reports in June 1993, a total of about 500 dinosaur egg fossils have been discovered around the world, of which only about 100 are dinosaur egg fossils containing embryos.
With the continuous discovery of dinosaur egg fossils, the total number of dinosaur egg fossils discovered around the world is constantly increasing.
"Everyone, be careful. There are probably dinosaur egg fossils under the Iguanodon fossils. From now on, the excavation work under the mountain must be careful and careful." Cao Meili quickly circled around the hill.
By the way, I would like to remind all students not to destroy possible dinosaur egg fossils. (To be continued.) Mobile phone users please visit http://m.piaotian.net
