Still alive 200 million years ago

It has been five days since Xu Dong arrived in this ancient and wild world. The creatures here are not as delicate as those in later generations. How can they give you such a long period of development time in infancy? Basically, as soon as you are born, you learn basic walking, hunting and survival knowledge from your mother. I have to find something to eat by myself.

In the past five days, relying on human intelligence and the enhanced attributes of essence, Xu Dong's hunting efficiency was far better than that of others of his kind. When the amount of essence harvested reached ten points, he finally entered the creature editor.

The biological editor is a circular space of tens of square meters, and the current time information is displayed on the outer layer of the circular glass cover.

[Time: 2.34Ma—Late Triassic Carnian Period

Location: The North American desert belt on the southeastern side of Laurasia, the unmeasured vastness of the desert and the nameless Gobi.

Climate: 45℃, dry and hot]

Xu Dong was a little surprised. It didn't start from the Indian period, but the Carnian period in the late Triassic?

In the center of the ten-meter-cubic space is a motionless virtual model of an adult little red lizard. Xu Dong can modify the body of the little red lizard, but any transformation requires spending the essence.

For example, to lengthen the neck, you can add a section of bone, each bone and a bit of essence.

The neck cannot be stretched infinitely, it must conform to the anatomy of the body. With a body as small as a red lizard, the neck that can be stretched by two sections is already as high as the sky.

At present, the innate components of the body of the little red lizard include:

[Sharp Teeth] are sharp, but they can only bite, not chew like beasts.

[Quick Ejection Tongue] An exclusive component for the little red lizard, which can better capture insects.

[Red heat-insulating and moisturizing cuticle] has strong water retention ability, strong heat dissipation ability, and strong hiding ability.

[Short Short Legs] Crawling close to the earth, feeling the pulse of the earth, with strong concealment ability and fast running speed.

These four are the components that the Gobi Red Lizard now has. Except for the projectile tongue, they are basically inherited from the Red Lizard. A genetic mutation often represents the birth of a new species. This is wonderful evolution.

It may be just a slight change in one evolution, or it may be completely different after one evolution, or it may be found exactly the same as the ancestors of other races after evolution. There is nothing more wonderful about the evolution of species than this.

If it weren't for archaeological discoveries, who would have thought that the ancestors of birds were dinosaurs? Who in ancient times would have thought that human beings are not creatures created by gods, but have the same origin as many mammalian creatures?

Therefore, Xu Dong also has the ambition to evolve the Gobi red lizard into a real giant dragon, but this goal is still too far away. Let's survive in the Triassic Period in front of us first.

According to the time displayed in the biological editor, 15 million years have passed in the Triassic at this time, which is exactly in the Carnian stage of the Late Triassic, and is only one year away from the legendary Carnian flood event. Millions of years.

I don’t know if the little red lizards in Xudong can survive the heavy rains of the Carnian period, or even live to the Jurassic period 30 million years later. Looking at the legendary dinosaur dynasty, thinking about such a long time span , Xu Dong felt unreal.

Think about it, it only took less than 10,000 years for human beings to go from growing up and drinking blood to going to heaven and going to the sea. In this era, ten thousand years are not even qualified, and all events start at least one million years ago.

Letting the little red lizard survive, reproduce and evolve over time is Xu Dong's top priority now.

Even in the arid Gobi Desert, there is still an ecological niche that is enough for thousands of little red lizards to survive. After all, creatures like the Zerg that can adapt to any environment are really a life-saving straw for small creatures.

"Boom!"

"Boom!"

"Boom!"

The vibration of the earth was immediately felt by Xu Dong, who was lying on the ground basking in the sun. He stretched his neck and looked around, wondering what the situation was.

The curiosity of the terrifying upright apes helped them explore the world and invent a variety of tools. However, in this era when exotic beasts are everywhere, for creatures with a low-end ecological niche like the Gobi red lizard, curiosity can only Kill the lizard.

I saw the same kind of insect predators around me running around like crazy, and disappeared in the blink of an eye. Xu Dong just thought for a moment, and in this moment, countless behemoths ran over in darkness.

They are huge, strong, and shaped like a wild boar. They look like ordinary pangolins, covered with a layer of leather armor, with a huge head, two large teeth growing on the canine teeth of the upper jaw, a thick body, a short and thick tail, and a silly look.

Kenshimon!

Xu Dong recognized this big straw bag at a glance. After all, this guy's reputation is quite high. It succeeded Hydrosaurus and became the number one pig in the Triassic. It was eaten by predators such as crocodiles, pseudocrocodiles, and dinosaurs.

Fortunately, it was such a big straw bag, so there was no need to worry about being eaten, but Xu Dong was obviously happy too early.

Although the Ken's beast is a vegetarian creature, it has no intention of protecting the weak. Even the little red lizard, a small animal no bigger than their feet, turned into a ball of meat paste when it stepped on it. This was worse than being eaten by a carnivorous creature.

Ken's beasts, a large herbivorous mammal found throughout Pangea, were huge in size and numerous in number. They were the second herbivorous beast in the Triassic after Hydrosaurus, and provided abundant resources for carnivores. food sources.

In terms of environmental adaptability between the beasts and dragons at this time, the dragons have an advantage. After all, the endothermic beasts are cold-tolerant, while the ectothermic dragons are heat-resistant. At this time, the Triassic is a living furnace.

The disadvantaged components of the version, such as sweat glands and urination, completely wiped out the advantages accumulated by the Orcs in the Permian, and also gave the Dragons an opportunity to rise.

So much so that by the Triassic, the carnivorous beasts were almost extinct, and the entire Synapsid class could only rely on a few big idiots such as Hydrosaurus, Kensaurus, and Lisovius to support the scene.

However, even this idiot is still a giant to Xu Dong now, and his existence can be erased by just stamping his feet.

Food was scarce in the arid early and mid-Triassic period. The huge Ken's herd had eaten up all the plants in an area and was about to migrate. Unfortunately, the migration route of the Ken's herd this time happened to pass through the area where the little red lizard was. Gobi.

Just when Xu Dong was enjoying the spectacular scene of all the beasts running together, the Ken family's herd had already come closer. Xu Dong, who was awakened by the wind pressure, realized that he was about to be trampled to death!

He immediately ran away. In the past, he never understood why the protagonist in the movie always had to follow the direction of the chasing animal when being chased.

Now he still doesn't understand. After all the ten points of energy he accumulated were invested in agility, he narrowly escaped the route of the Ken family's beasts.

I climbed up the Gobi rock next to me three times and five times, and looked down at the Kenshi beast running, with smoke and dust billowing up in the endless curling yellow sand. The scenery was really spectacular.

Behind the smoke, three different figures were discovered.

Ken's beasts were just moving lumps of meat in the Triassic. They would attract predators almost wherever they went, but the three predators behind them were beyond Xu Dong's expectation.

One of the predators following Ken's beast is the small main dragon Herrerasaurus, also called Black Ruilong, which follows and feeds on Ken's beast all the year round.

Although it was usurped by Eoraptor as the earliest dinosaur, it can still be regarded as one of the earliest veterans of the dinosaur family.

Herrerasaurus is 1.5 to 2 meters long and weighs 150 to 200 kilograms, which is less than half of the Ken's beasts. However, there are many of them. They follow the Ken's beasts in groups and see organic If you can take advantage of it, you will get into trouble.

The second branch is amazing. It is currently the leader of the dragon family and the top predator in the Triassic. Archosaurs-pseudosuchians-parasuchiformes-Lausuchiidae-heptasuchians!

It looks like a crocodile from the future, but the front limbs are a bit shorter, and its body size can reach an astonishing six meters. However, Crocodile crocodile is also divided into different genera. The two Heptosuchus here are only a little larger than the genus Crocodile, which is estimated to be only four meters. left and right.

The last one is neither a dragon nor an orc, but a race that has long withdrawn from the dominance stage, the Zerg! One, a huge brown scorpion.

Xu Dong didn't know what this giant scorpion was. Didn't it mean that the Zerg had given up on becoming gigantic long ago? Why do such big scorpions still exist?

This brown scorpion is larger than Crocodile crocodile. Including its long scorpion tail, it may be five meters long. It looks almost the same as scorpions of later generations. The only difference is that there is an extra pair on the mouth. Huge, sharp, curved claws.

It is not scientific at all that such huge bugs still existed in the Triassic Period. No fossils have been discovered in later generations. However, the fossils that can be excavated from the strata only account for one ten millionth of the biological species at that time and have not been discovered. It’s considered normal.

Before the heavy rains of the Carnian period changed the continental environment, the entire Pangea continent was full of desert Gobi, with sparse low plants, stone pines, knotted ferns, and two-pronged ferns.

Food is scarce and supplies are scarce. Even the apex predator Crocodile Crocodile is often hungry. Fortunately, there are also water dragons and kennedy beasts with strong fertility but weak combat and defense capabilities. They are big straw bags that can eat any plant. , giving predators a chance to develop.

In the great desert at the moment, the little Gobi where the Little Red Lizard Clan is entrenched, with such a large group of Ken's beasts, how could any predator be willing to miss it?

Small Theater of Paleontology: As mentioned in the previous chapter, Sauromorpha is divided into Archosauria and Lepidosauria. Archosauria includes archosaurs, and the main archosaurs are pseudosuchians and ornithopods. Pseudosuchians are the ancestors of today's crocodiles. They were the overlords in the middle and late Triassic. Ornithosuchians are divided into dinosaurs and pterosaurs.

The classification of Herrerasaurus is Sauromorpha - Archosauria - Ornithopoda - Dinosauria - Saurischia - Herrerasauridae - Herrerasaurus genus.
