Still alive 200 million years ago

A small lizard with a body length of only six or seven centimeters but a wingspan of about twelve centimeters flapped its wings and flew to the surrounding fir trees, tilting its head and staring at the food below.

Xu Dong was confused. His first thought was that he had finally found a flying lizard. His second thought was that it turned out that the scaly dragon could really fly.

In previous lives, disputes have never stopped since the appearance of the Longisquamosaurus fossil. The reason lies in the multiple strips on its back. The strips are long and narrow, with the tail end facing backward, and they look like a hockey stick. But the vertical part of the long attachment has a protruding ridge in the center, which feels like a plant leaf.

Different scholars have different explanations. Some scholars believe that Longisquama was just a lizard lying on a fern, but it was later proven that the strips on its back were not plants.

Some scholars believe that Longisquama is the origin of birds. The strips on their backs are two rows of paired feather-like structures, and the position attached to the body is also similar to the feathers on the spine of birds. Based on this, they believe that Longispiosaurus is the origin of birds. are cold-blooded, gliding primitive birds and conclude that birds are not descendants of dinosaurs.

Arguing scholars have suggested that these structures are very different from feathers, and suggest that they are elongated, ribbon-like scales attached to the sides of the body in pairs, like a pair of gliding membranes. They reconstructed Longisquama and described these structures as similar Cone lizard-like wings.

Of course, some scholars believe that Longisquama is the direct ancestor of pterosaurs.

Xu Dong was not interested in the academic debate at all. All he knew was that the long-scaled dragon could really fly, and its wings were different from leather wings, feather wings, skin membranes, and insect wings. This was a brand new one. Wings made of special scales.

Although it is still unclear how capable these hockey stick-like scaly wings are at flying, naturally the more wings that are related to flying capabilities, the better.

For the wings of this long-scaled dragon, Xu Dong saved the flesh and blood that was supposed to be eaten in his stomach, then dragged it to the cave where he lived, and hid in the cave himself. He wanted to use this piece of flesh and blood to lure the beasts on the tree. Long scale dragon.

After a small Talampea crocodile finished its food, it looked around and found a piece of uneaten flesh not far away. His eyes suddenly lit up, and he approached the piece of food cautiously.

Xu Dong suddenly became unhappy. I'm fishing here, why did you come over to cause trouble? He immediately jumped out of the hole, chopped the troublesome guy to death with a knife and threw him into the hole.

However, the fishing plan was ruined. A six- to seven-centimeter little guy like the long-scaled dragon is very vigilant. After seeing an ambush at the entrance of the cave, it is impossible to come down again.

Now he had to be tough. Xu Dong quietly climbed up the cedar tree where the long-scaled dragon was, wanting to make a final surprise attack, but how could it catch the flexible long-scaled dragon on the tree? Before he could pounce, the little guy flapped the seven pairs of scaly wings on his back and flew away.

Xu Dong, on the other hand, looked up and watched the long-scaled dragon fly away. He didn't pay attention to his feet for a moment. His right foot instantly stepped into the air, and the entire lizard fell from the tree.

Fortunately, the small tree was not tall enough and there were many dead grass and leaves at the bottom, so I was not injured by the fall.

After the previous battle with the Skerosaurus and the brief encounter with the Long-Scale Dragon, Xu Dong understood that the version 1.0 of his Little Red Dragon was somewhat behind the times. There was no problem on the ground, but in the trees it was Totally not flexible enough.

He began to wonder whether he should make some fine-tuning. The previous transformation planned by Xu Dong was a major version update such as 1.0-2.0-3.0. All aspects of the whole body would be transformed to directly evolve the little red dragon into a complete body.

But now Xu Dong’s idea is to make a small update first and install the [Triassic Tail Frog’s Bouncing Bare Bone] component on the little red dragons, so that they can flexibly cope with the arboreal environment, and the evolution corresponding to the small update The time should also be much shorter, and the direction of transformation can be better adjusted based on actual conditions.

Without strong jumping ability, let alone flying into the blue sky, it would not even be able to catch flying lizards such as long-scaled dragons and konai lizards.

But before that, they still have to let the little red dragons learn to climb trees. Otherwise, without their own supervision, and there is no shortage of food here, due to the inertia of creatures, these guys will never learn to climb trees on their own.

Everything is back to how it was more than half a month ago. The little red dragons climbed up the tree, fell down, climbed up, and fell down.

It's just that this time the little red dragons have made great progress. For example, Long Jiu is now able to climb trees very skillfully. Although he is still a little cautious when walking on the branches, he is already better than most of the little red dragons. .

There are a total of thirteen little red dragons, and they have basically learned to climb trees. However, seven or eight of them are still at the level of inserting their claws into the trunk of the tree. They are very heavy and slow.

Just when Xu Dong nodded happily and felt that the transformation could be carried out, he suddenly realized a very serious problem. Among the thirteen little red dragons under his command, there was no female!

I had been migrating before and didn't think anything of it. Now I have arrived at a suitable habitat and want to start reproducing, only to find out that it is nonsense. What should I do?

Waiting online, quite urgent.

How can a tribe rely on a bunch of males if it wants to thrive? Unless Xu Dong is lucky enough to draw hermaphrodites or parthenogenetic components.

And according to Xu Dong's understanding, most parthenogenetic reproduction is parthenogenetic, which is almost useless to big men like Xiao Chilong.

What's more, Xu Dong didn't know where to find parthenogenic creatures. He might as well let the little red dragons mate around to see if there were any non-racially segregated species that could be interbred with.

The idea of ​​​​carrying out small-stage evolution in advance can only be temporarily shelved. If the little red dragons are really unable to reproduce, then even if Xu Dong is transformed, can he still come out without species in reality? You can hit GG directly.

Xu Dong decided to catch it with both hands, and at the same time sent the little red dragons to attack everywhere, looking for nearby creatures such as Skererosaurus and Talampea Rabbit Crocodile to see if they could mate and reproduce.

On the other hand, I went to the beach to see if I could touch the androgynous components.

The hermaphroditic animals that Xu Dong knew about include snails, eels, and various shellfish. I don’t know if snails, eels, or eels have evolved now. There is no shortage of shellfish. Just go into the water and touch them.

After that, the little red dragon group had two tasks: one was to climb trees, and the other was to mate.

The estrus period of lizards can be from spring to autumn. Although it is not the beginning of spring, it is also the time when everything in Pangea is recovering. The air in the mountains and forests is filled with the smell of hormones.

The hormones that the little red dragons had suppressed for three years suddenly exploded, making small creatures such as the female Skererosaurus, Talampea crocodile, and Aon's two canodons intolerable.

It also makes the males deeply disgusted, and they staged scenes of prehistoric crimes.

But what can they do? The little red dragons have already established a firm foothold, and their sharp claws make them nearly invincible among small predators of the same size.

And they also learned to climb trees. Although they didn't climb very fast, being able to climb trees meant that Skererosaurus and Talampea Rabbit Crocodile had no advantage over them.

After a long time, Xu Dong received good news and bad news.

The bad news is that he has been touching the clam for so long and nothing has come out.

The good news is that a female Aweng's canine-toothed lizard that was captured by the little red dragon and kept exporting is pregnant.

Paleontological Theater: The long-squamosaurus is very special, mainly because of the strips on its back. Both the material and its classification are highly controversial.

One is that there are no strips on the back of Longisquamosaurus, and the strips are plant fossils. Of course, after many Longisquama fossils were unearthed, this statement was rarely mentioned.

The second category is that there is only one row of strips on the back of long-scaled dragons, so that the strips on their backs are not wings but a tool to show off. However, in the dangerous jungle, there are several strips on the back that are longer than the body length. Strips, I'm afraid they don't die quickly enough. In fact, the long-scaled dragon lived from 242 million to 228 million years ago, a full 14 million years. Obviously, the possibility of decoration is very small.

The third group believed that Longisquama was the origin of birds, but was slapped in the face by various evidences. This was just convergent evolution.

The fourth category is considered to be the ancestor of pterosaurs.

In short, the long-scaled dragon is a very strange creature, full of mysteries.
