Behind a bush on the cold plateau, Yu Xian patted off the dust in his hand and returned.

Fighting took place two days ago, indicating that enemy pangolins had touched the vicinity of the cemetery.

Yu Xian killed four enemies, leaving no one alive, and his companions would chase him in the direction where someone was missing.

According to the worst-case scenario, it is better to leave the tent in place, as long as the enemy is nearby, the first time to find the tent and search the surrounding area, it is also convenient to find them at leisure.

Use the tent as bait and hide a portion of the food so that it cannot be destroyed in battle or taken away by the enemy.

After finishing these, I hid the fossils of the big ditch dragon and the parrot-billed dragon, and calculated the time again.

It has been more than 20 days since the six households entered the cemetery, during which time Yu Xian not only dug up fossils, but also sent a paper on the toy pterosaur to the editorial department of "History Hook Shen".

I didn't dig up fossils at the bottom of the canyon for the past two days, but I was making changes according to the feedback from the editors.

Now the revised version has been sent to the editorial office again, and it will be published next month after passing the review.

The academic results are going quite well, but I am a little worried about them.

The last time I entered the Lianchi Mountain Range, the main reason why I was trapped in the cemetery for a month was that the suspected mound collapsed and wasted a lot of time in the underground cave.

There are no underground caves on this side of the Hanjiang Plateau, so these times should come up.

Yu Xian specially returned to the tomb behind the statue of the Holy Aunt to check, the safety rope was still hanging there, and Bai Mo showed no signs of climbing up.

Because of the concerns in his heart, Yu Xian also specially contacted Bai Guanshan a few days ago, but the other party did not answer the phone, and there was no reply after three or four days.

"With their ability, they won't overturn..."

In the final analysis, Yu Xian can only choose to believe in the tomb robbery skills of the six peerless households, and do his job first.

There is a marker at the bottom of the canyon that has not been dug up.

At first, there were two ancient atlases and two dragon hunting atlases, and two dinosaur fossils had been dug up, plus a cornerstone.

There is also a pointer left, which also belongs to the guidance of the ancient atlas.

"As long as it's not an ammonite, other paleontology is fine."

It's good to have another cornerstone, otherwise Yu Xian is like a knight on the Feathered Tyrannosaurus, but his hands are empty, and he needs to have a weapon in hand.

Descending to the bottom of the canyon, the frequency of the beating is very low after the pointing mark turns vertically downward, and the shape is relatively blurred, indicating that the fossil is buried relatively deep.

As the excavation progressed, the pointers changed from one to two, indicating that there should be two fossils underneath.

It took half a day to dig more than ten meters of ground, and the point mark poked downward, poking on a rock the size of a laptop.

The surface of the fossil reveals the shape of two fish, with a head and tail length of about 30 centimeters, which is not much different from the appearance of today's fish.

The bones of the two fish overlap top and bottom, one pressing the other.

“… Snapping? Is this something that can be seen for nothing? ”

Paleontological fossils are quite a rare thing, especially some lifelike dynamics have been preserved.

For example, other countries have dug up a group of fossils of Protoceratosaurus and Velociraptor fighting.

Halfway through a fight, the dust or torrent just arrives, burying them completely, forming fossils, and preserving the posture of the fight before their deaths.

This group of fossils is called "dinosaurs in a fight", and they fought for 60 or 70 million years.

The two dinosaurs have been thoroughly studied, the fossils themselves are nothing sensational, and what is really rare is the integrity and preservation posture.

What should these two overlapping guys be called...

"Snapping fish?"

The posture is really good, but unfortunately it is impossible to tell what kind of paleontocrat they are just by looking at their appearance.

Yu Xian subconsciously felt that it should not be too old, but when he saw the updated content of the ancient atlas, he couldn't help but drop his jaw.

Dream ghost fish, fossil integrity 67%, 59%

“woc。”

The name of the fish is very fantastical, which shows how special it is in the eyes of archaeologists.

400 million years ago, the Silurian period.

It was still early for animals to appear on land, and chordates in the ocean were only predators living on the bottom.

Gradually, as these animals survived, the notochord evolved into vertebrae, forming a nerve center that connects the entire back from the brain.

Then the bony fish was born, and the flesh-finned fish evolved.

The fleshy fins gradually turned into limbs and landed on land, becoming various vertebrates on land.

So, the ancestors of all vertebrates, including humans, have to be attributed to bony fish.

The appearance of bony fish should not be so early, but scientists accidentally discovered dream ghost fish in fossil strata, moving the origin of vertebrates back tens of millions of years.

It is precisely because the fish with a spine should not appear at such an early time, describing it as a ghost in a dream, that it has such a name.

So far, there have been studies on the ghost fish, but the number of fossils is not very large.

This thing is very expensive, it is no longer a question of how birds evolve, it is a common source of all vertebrates.

Even if there is nothing to write a paper on the fantasy ghost fish fossil, the value of this fossil is still undoubted, not to mention that they are pressed one by one, and the dynamics can be preserved.

If Yu Xian had established a paleontological institute and obtained an officially recognized qualification to buy and sell fossils, the price of this thing would be immeasurable.

No... Yu Xian shouldn't sell it, the fantasy ghost fish is enough to use it as a treasure of the town.

The fossil of the dream ghost fish is much more convenient than the big ditch dragon, and the thickness of the rock is about the level of a desktop computer case.

Pack it into your hiking bag and climb the cliff with ease.

Big ditch dragon, parrot beak dragon, fantasy ghost fish.

This is the harvest of Yu Xian's trip to the cold plateau.

Dashuigou dragon has extremely high paleontological value, go back to study and study, let the world know that it should be classified in the family Sharkodontosauridae.

The dream ghost fish is more of a paleontological romance, a kind of artistic atmosphere that has come from time immemorial and is natural.

Of course, it is also possible to study the breeding characteristics of the dream ghost fish from the fossils.

Psittacosaurus is more ordinary, there are too many fossils, take it back and make an ordinary collection.

There is also the cornerstone below, which is idle and idle, so dig it out.

Yu Xian has already begun to think about how to make the people of the Six Peerless Households willing to help without directly helping the tomb robbery activities.

As long as you are willing to help bring the Dashuigou dragon fossil to the vicinity of the scenic spot, don't expose the real fossil excavation site, Yu Xian may have to come back in the future to continue to expand the search.

Thinking of reasonable rhetoric in his mind, Yu Xian returned to the bottom.

It's still a few hours before dark, so it's not a bad idea to try it out and pull out the cornerstone and put it in the house to make a craft.

Just do it.

This thing is a cone, and the friction is small, so Yu Xian dug down again, shaking the corner stone back and forth to loosen it whole.

Then pull upwards firmly.

Slap sand.

The fossil was extracted intact, and there was a cavity the size of a bowl in the ground, extending to a depth of five or six meters.

At this moment, words came from the hollow.

"Who is it?!"

"Huh?" Yu Xian was stunned for a moment, only to feel that the voice was very familiar, "Bai Mo? I'm Yu Xian. ”

"Great!"

There were cheers from underground, "Yu Xian has come to save us——! ”
