"Huh? Ask where I'm going? ”

"Yes, they didn't enter the quartz cave, they only walked around the scenic area once, and then they saw me under the banner of the scientific research team, and asked Mr. Yu where he went, saying that he wanted to cooperate with you."

Encountering such a group of unknown origins, Xiao Xuri certainly didn't stupidly talk about Yu Xian's situation, and he really didn't know where he was going.

When communicating with the audience in the live broadcast room, Yu Xian directly explained that he would do further investigation on the Hanjiang Plateau in the near future, and Xiao Xuri's response was the same:

I only know that Mr. Yu is investigating on the cold plateau, but I don't know where he went.

"Well... It's okay, it's okay, it's probably a paparazzi-like news practitioner in the media circle, who will do everything to dig up the news, and they can't find me anyway. ”

Yu Xian Xinzhou was already thinking about various possibilities, and he didn't say anything about it, so as not to add additional anxiety and psychological burden to Xiao Xuri.

For him, the most important thing at this stage is to stabilize the Shenggu Mountain Scenic Area.

The call ended, and Yu Xian quickly returned to the bottom.

It's too cold up there.

The power bank connected to the solar panel is specially stuffed in a thick glove to prevent it from freezing at low temperatures.

A fire was lit outside the big tent, and Yu Xian thought carefully about Xiao Xuri's words.

It's okay to ignore them as paparazzi, but it's more likely to be fossil hunters.

Fossil hunter, a professional household that hunts fossils.

It would be a mistake to think that they are very good at digging fossils.

It's not just fossils that hunt, it's also people who dig up fossils.

In the wilderness, where the legal society cannot be restrained, whoever has ruthless methods will own the fossil results.

Fossil hunters attacking regular fossil exploration teams are not uncommon, simply because the circle is relatively small and there are few stories to circulate.

If you really want to describe it, it's a bit like a pangolin attacking an archaeological team.

Yu Xian didn't think that he was so hot that he deserved a paparazzi, and the possibility of fossil hunters was higher.

"It doesn't matter, how can you track it down here."

No one knows Yu Xian's specific course of action, or even where Yu Xian is on the Hanjiang Plateau.

It may be in the cold snow city, it may go to other cities, and the uninhabited area of the Hanjiang Plateau is looking for a needle in a haystack.

Not bothering to pay attention to the fossil hunter of unknown origin, Yu Xian turned his attention back to the fossil pit dug yesterday.

The quagmire dragon is still in it.

According to the results of existing paleontological research, the quagmire dragon could run at a speed of more than 50 kilometers per hour, chasing the carbourous carnosaurus.

"It's still hard to escape the quagmire if you run so fast..."

The name is really joyful, and it is funnier than the big ditch dragon.

Click.

The shell of a USB flash drive was shattered, the metal was slightly twisted, and the chips inside smelled of burning.

At the cost of the U disk, it was inevitable that the stones adhered to the forelimbs of the quagmire dragon fell off, and the fossils were peeled off intact.

The two small branch-sized fossils are not really connected to the large mountain, and the trouble is only the small stones that are partially embedded.

Using basic techniques and tools to separate is not only troublesome, but the slightest mistake or bad luck will cause damage to the fossils.

As the sunset dissipates, the temperature at the bottom of the canyon drops dramatically.

Yu lit a bonfire, wrapped the large bones of the inevitable quagmire dragon in plastic wrap, and put the scattered finger and claw parts into a plastic sealed bag one by one.

"One, two, three, four... Four fingers. ”

At this stage, the only one that is open to the public is that the quagmire dragon has no forelimbs, and the fossils dug up by Yu Xian are quite complete in front, so he is naturally extra careful.

It can be seen that this quagmire dragon is younger than its predecessors in the paleobiosphere, and its bones are relatively slender and in its juvenile stage.

There appear to be only three forelimb claws, but one of them is so degenerate that it is almost impossible to distinguish.

Yu Xian originally thought that the scientific research results he got were at most how many fingers and claws this dinosaur had, but at this time, he looked at the plastic sealed bag and was stunned.

Adjusting the orientation of the forelimb bones, the most severely degraded finger can be seen on the inside of the groove, which is equivalent to the position of the human thumb.

In the eyes of outsiders, there is no problem, but it is quite shocking for leisure.

Sauropods, ornithopods, and early carnivorous dinosaurs all had five fingerclaws on their forelimbs, and gradually became three fingerclaws on their forelimbs when they transitioned to birds in the later period.

No problem here, the Inevitable Quagmire is indeed showing the process of dinosaurs degenerating their fingers.

What really shocked Yu Xian was that so far the paleontosphere believes that in the evolution of dinosaurs into birds, it was the two fingers that gradually degenerated.

Again, take humans as an example, which is equivalent to the loss of the ring finger and little finger, leaving the remaining three fingers.

It is difficult to escape the quagmire dragon degradation, and the serious is the "thumb" position.

Take out a fairly complete comparison of the two metacarpal bones, there is no "little finger", but there is still a small space corresponding to the little finger.

This is enough to prove that the evolution of the straight claws of the dinosaur's forelimbs was not to degenerate the outermost two, but to degenerate the thumb and little finger, leaving the middle three fingers.

In addition to the skeletal representation, the appearance of the Inevitable Miremiresaurus is also very coincidental, appearing earlier than Archaeopteryx, and has a beak that looks like a feather and beak, building a bridge for the study of the evolution of dinosaurs into birds.

With such a change in fingers alone, Yu Xian believes that after writing the paper, it will be difficult to escape the academic factor produced by the quagmire dragon and will not lose to the odd pterodactyl.

The key is to get the paper written...

There is no reference in the "Xueba Library", and the fossils of the quagmire dragon known in the real world are missing forelimbs and finger claws, which greatly tests Yu Xian's writing and argumentation skills.

I didn't expect there to be such a big treasure in the details, so Yu Xian carefully put away this part of the fossil.

Tomorrow, I won't expand the scope of my search, sit down and organize my writing ideas, and continue to think in the process of aimless searching.

Then there is the beak of the quagmire dragon, which has separated from the upper and lower jaws due to the loss of musculature and cartilage.

Yu Xian took out two plastic sealed bags and stored them separately to avoid rubbing and bumping in the same bag.

Storing such a small action separately, Yu Xian paused again.

"Can't escape the quagmire dragon... Teeth in the mouth!? ”

The "Xueba Library" and the fossil of the Inevitable Mire Dragon published on the current world online have a more complete head than Yu Xian's side, and a beak similar to that of a bird, with no teeth inside.

And the fossil in Yu Xian's hand obviously has teeth in the upper and lower jaws...

Comparing the goods in their hands, looking at the published paper data, the difference between the two sides of the quagmire dragon is that they are adults and minors.

Yu Xian's hand is just a juvenile quagmire dragon, it has teeth.

Exclusion of outrageous genetic mutations.

Escaping the quagmire dragon has teeth in its juvenile years, and its teeth fall out as it grows.

This is the process of change from "dragon teeth" to "beaks" of birds.

"I underestimate you."
