Speaking of straight-shelled nautilus, it has a long history on Blue Star.

In its heyday, the strongest competitor it encountered was the horseshoe crab.

The two started an evolutionary race in the middle of the Cambrian period.

Until the end of the Cambrian period, the straight-shelled nautilus had the upper hand.

After experiencing the end-Ordovician extinction event.

The straight-shelled Nautilus was severely weakened and eventually lost to the Horseshoe Crab.

But it still maintains a very high status in the ocean.

In the Devonian period, due to the emergence of Dunkleosteus, the horseshoe crabs in the sea were forced to move to land.

Because the straight-shelled nautilus could not go ashore, it was oppressed by Dunkleosteus and completely lost its dominance.

Then came the appearance of the Helicoprion shark in the Permian.

This makes the straight-shelled Nautilus family dying.

It was not until the Triassic period that ichthyosaurs ruled the oceans and the straight-shelled nautilus became completely extinct.

Ye Yuan was able to find a straight-shelled nautilus shell here today. He couldn't believe his eyes.

He reached out and touched the shell in front of him.

I found that the shell of the straight-shell nautilus was not as ugly as I thought. It felt like jade to the touch.

This made Ye Yuan couldn't help but feel surprised.

You know, it is great luck to find a straight-shelled nautilus.

Not to mention, the one he discovered was a jade shell.

Such a thing simply cannot be described by probability.

This is like the national football team entering the World Cup and winning the championship in one fell swoop.

With such a probability, no one would believe it even if it were told.

The transformation of the shell into jade is a coincidence and a very long process.

First of all, after it dies, its chitin will be buried in the seabed by sand and sediment for tens of thousands of years.

organic gemstones

It is also known as the "undersea jade" that is extremely natural and spiritual.

This process is not only long, but also full of uncertainties.

It can be said that a shell wants to be successfully transformed into jade.

The probability is almost one in hundreds of millions.

As for the shell of a huge straight-shelled nautilus, the probability of it becoming jade is even smaller.

Maybe I found this jade-shaped straight-shelled nautilus.

It is the only jade nautilus in the world.

Ye Yuan couldn't even imagine how much of a shock it would bring to the entire biological world if he took out such a straight-shelled nautilus that had been transformed into jade.

Usually, the straight-shelled nautilus found by people is presented to the public in the form of fossils.

Therefore, for some scholars who want to study paleontology, fossils are certainly not as valuable as directly studying snail shells.

Ye Yuan knew very well the value of the nautilus placed in front of him.

I believe that in the eyes of many biologists, this thing can be described as priceless.

Of course, Ye Yuan would not sell it just because of its value.

Ye Yuan decided to collect this jade straight-shelled nautilus.

With a wave of his hand, the snail shell that was still lying quietly in the sea sand was taken into the space by Ye Yuan.

After putting away the extremely precious straight-shelled nautilus, Ye Yuan became even more interested in this shellfish cemetery.

He didn't know how the shellfish here gathered here.

How to die here.

…

But what I have to say is that the shellfish resources at the bottom of this trench are extremely rich.

Although they are all dead shells, countless shells will be broken every time you step on them.

But Ye Yuan still watched carefully.

Take a look here, will you find some precious shells?

shell.

Ye Yuan is not a shellfish collector, but because of his innate advantages, he has an extremely rich variety of shells in his home.

Although no more valuable shells were found.

But as Ye Yuan stepped out, a round black pearl rolled out from the shell that was crushed by Ye Yuan.

Ye Yuan originally thought that the pearls in this sea area had lost their luster over time.

But with the appearance of this black pearl, he realized how naive his previous thoughts were.

The reason why pearls lose their luster is because the main ingredients contained in pearls are calcium carbonate and water.

Calcium carbonate will cause a layer of pearl-specific luster to appear on the surface of the pearl.

But as the calcium carbonate in the pearl gradually loses.

Until eventually the pearl loses its unique luster and no longer possesses the qualities of pearls, and such pearls completely lose their value.

But the sudden appearance of this black pearl brought hope to Ye Yuan.

Although this black pearl is also dull, it still has a certain value compared with those pearls that have completely lost their luster.

In other words, the calcium titanate in this pearl has not been lost, and it still has a certain value.

Ye Yuan picked up the black pearl and felt extremely emotional.

I still remember the time when I just returned to Yuwan Island.

The first pot of gold he got was selling a valuable black pearl with the help of Zhao Chuan.

After such a long time, Ye Yuan once again found black pearls on the seabed.

It's hard to tell what he's feeling right now.

There is excitement, melancholy and even a trace of reluctance for myself at that time.

No matter what, he found the black pearl again

The mood is still very beautiful.

The only flaw is that this black pearl is oval in shape and is not the top grade of black pearls.

It's not very big either, and most importantly, it's much inferior in gloss.

Even so, Ye Yuan still put away this black pearl, which was almost past its shelf life.

After all, black pearls are so rare that even I have only discovered them twice in such a long time.

After only staying at the bottom of the trench for a full hour, Ye Yuan obtained countless pearls.

But the vast majority are still mainly white, with some light yellows and pinks, and I can also find a lot of them.

We even found a gold pearl the size of a pigeon egg.

Just when Ye Yuan was about to leave, he sensed an unintentional sweep.

Suddenly I found a huge clam in the corner of the trench.

Tridacna is a marine animal in the class Mollusca and class Bivalvia.

It is the largest bivalve shellfish in the ocean.

Known as the "King of Shells" by many people.

The largest clam can reach more than 1 meter in length and weigh more than 300 kilograms.

Its shell is thick and heavy, its rim is like a tooth, the two shells are about the same size, and the inner shell is pure white and shiny, as white as jade.

The external ligament usually has a large byssal hole.

The hinge part has one main tooth and 1-2 rear side teeth.

If we talk about the ordinary clam, it is already a giant among shellfish.

Then the clam discovered by Ye Yuan is the Big Mac among the Big Macs.

This clam is over 3 meters in size.

If he didn't look carefully, Ye Yuan would have thought it was a huge rock.

Ye Yuan walked into the clam and easily opened its tightly closed gap.

Following Ye Yuan's movements, a blood-red object with a diameter of half a meter appeared.

Rolling out of the shell of this giant clam.

This was the first time Ye Yuan saw such a big pearl. Even in the information, he had never heard of such a big pearl appearing on Blue Star.
