Back to the Age of Dinosaurs

Both Gulumengge and Gaya looked at the other side of the Dada River, and the bang bang bang was like continuous thunder.

At first they heard only a continuous loud crash, and it was not from one or two dragons, but from many, many dragons.

Gulu originally thought that there were many triceratops groups on the other side who were "collectively courting". Triceratops always used collisions to finalize the most powerful triceratops in the group, and they also used this method to compete for priority mating rights.

But soon, Gulu found that his guess was wrong, because more and more pachycephalosaurs came out of the lush fern bushes, all kinds of pachycephalosaurs.

They had never seen such a wide variety of Pachycephalosaurus, and many of them were new species, which they had never seen before.

There are more than ten kinds of dragons under Pachycephalosauridae, and there are at least five or six kinds here.

Gulu roughly identified it. The subfamily of Pachycephalosaurus here includes: Dragon King Dragon, Styraposaurus, Tiltosaurus, Centrosaurus, Flat-headed Dragon, Pachycephalosaurus, and Pachycephalosaurus.

Before this period of time, all pachycephalosaurs had only one species, collectively known as pachycephalosaurus. At least Gulu had never seen any subfamily of pachycephalosaurus before, and this was the first time he saw it today.

I didn't expect to see so many kinds of Pachycephalosaurus for the first time, which really made Gulu feel incredible.

The most notable feature of Pachycephalosauridae is that there is a very large swelling on the head. The swelling on the top of their head is very hard, which can be said to be a purely natural "iron head skill".

In human popular culture, Pachycephalosaurus is a very famous dinosaur and often appears in major dinosaur movies.

In human movies, the iron head skills of Pachycephalosaurus can smash through very thick tempered iron doors, knock down a wall, and smash an armored vehicle. These are the most common operations.

Gulumengge and Gaya saw Pachycephalosaurus of various varieties colliding fiercely with each other.

All the dragons of Pachycephalosauridae belong to herbivorous dragons and live in groups.

Now there are seven or eight pachycephalosaur groups of different subfamilies on the fern planting ground opposite the Dada River, and each group has about a thousand dragons.

Seven or eight thousand Pachycephalosaurus fighting is really spectacular.

Pachycephalosaurus is a relatively stupid dragon, probably a little bit smarter than the dumbest Parasaurolophus. Their only defense and attack ability is to use their iron head skills to keep hitting.

Affected by various dinosaur movies, many humans believe that most dinosaurs have very low IQs, either they know how to bite, bite, or bump. These two stereotypes of dinosaurs mostly come from Tyrannosaurus rex and Pachycephalosaurus.

But much of human popular culture does reflect the most distinctive features of various dinosaurs.

Tyrannosaurus rex is brutal by nature, and when he kills, he will indeed kill all living things he can see.

In an environment with no sense of security, or when fighting, the pachycephalosaurus will hit like crazy, hitting whatever it sees.

The territory on the opposite side was originally the territory of Gujigudong and Guga, but now it has been occupied by a new Tyrannosaurus rex. It is also a group of sub-adult Tyrannosaurus rex. There are 8 of them in total, and each one is very strong. The overlord who can occupy the territory here There is no one in the dragon group who is not powerful.

This group of Pachycephalosaurus was fighting, and 8 Tyrannosaurus rex were waiting on the side. If Pachycephalosaurus was killed, they could pick up ready-made food.

Gulu saw a big tree, a big tree that can only be embraced by an adult with open arms, and it was smashed by the pachycephalosaurus three times, and the most powerful Triceratops could not break it in such a short time. Strong big tree.

Triceratops is definitely much more powerful than Pachycephalosaurus in all aspects, but it is indeed inferior to Pachycephalosaurus in terms of impact force. Triceratops mainly uses its long horns to assassinate, and relies on its huge weight to trample other dragons to death.

肿头龙的身体一般只有2-5长，1-3米高，体型最小的肿头龙亚科剑角龙体重不超过200斤，最大的肿头龙亚科就叫肿头龙体重有1.5吨。

Even the largest Pachycephalosaurus with a weight of 1.5 tons is completely incomparable with a dozen tons of Triceratops.

The impact force of Triceratops is not as good as that of Pachycephalosaurus mainly because the head of Triceratops is too big. The larger the area of ​​force when hitting something, the less likely it will be damaged. The head of Pachycephalosaurus is very small and hard. The force-bearing area is small, the bearing force is concentrated, and the intensity of the impact is just greater.

A Styrannosaurus fell to the ground, and the most impatient of the 8 Tyrannosaurus rex immediately ran over and wanted to eat the Styxosaurus in one bite.

However, before the Tyrannosaurus rex bit the big meat into its mouth, a very huge Pachycephalosaurus and the leader of the Pachycephalosaurus group weighed at least 2 tons. hit the belly of the Tyrannosaurus rex.

This tyrannosaurus rex is the thinner one in the group, weighing about 9 tons.

The 2-ton pachycephalosaurus collided with the 9-ton Tyrannosaurus rex. This collision looked fierce, but the Tyrannosaurus rex remained motionless, as if it was not affected at all.

If a Triceratops leader hit the Tyrannosaurus rex's belly accurately, even if the long horns did not penetrate, the impact force alone could knock the Tyrannosaurus rex away, or even knock it to the ground.

But the 2-ton pachycephalosaurus obviously couldn't shake the 9-ton Tyrannosaurus rex.

The Tyrannosaurus Rex continued to eat the Styrannosaurus rex nonchalantly, but just after taking a bite, before he could swallow it, the corner of the Tyrannosaurus rex's mouth kept bleeding, not the blood of the prey, but the blood of the Tyrannosaurus rex itself.

This kind of pachycephalosaurus with an average weight of 1.5 tons is a new breed recently. The previous pachycephalosaurus weighed only a few hundred catties, and there has never been a pachycephalosaurus of such a large size.

Tyrannosaurus rex have no experience, because being hit by the previous pachycephalosaurus has no effect. No matter how powerful a pachycephalosaurus weighs several hundred kilograms, the impact force is not enough to kill the tyrannosaurus rex.

But the 2-ton pachycephalosaurus was a different story.

The Tyrannosaurus rex spat out the meat that it hadn't swallowed yet, and blood gushed out of its mouth continuously, as if it was about to spit out all the blood in its body, which looked very terrifying.

Even if the triceratops knocked the tyrannosaurus to the ground, it would not be fatal. The tyrannosaurus was just knocked down by the weight of the triceratops. The large force area would not damage the internal organs.

Even though the pachycephalosaurus leader didn't shake the Tyrannosaurus rex at all, it had already ruptured the internal organs of the Tyrannosaurus rex. This is the terrible thing about the concentrated force.

After the male Tyrannosaurus rex vomited a lot of blood, he fell to the ground with a bang, convulsed and soon died.

The other 7 Tyrannosaurus rex looked at all this in disbelief. They couldn't believe that their brother was directly killed by the pachycephalosaurus!

Since then, Tyrannosaurus rex has known the power of the new species of pachycephalosaurus.

Gulu didn't know why these swollen-headed dragons fought at first, but he knew it after watching it. The reason why these swollen-headed dragons fought with the big dragons in the sea was the same.

All Pachycephalosaurinae want to use the name Pachycephalosaurus, but they are already completely different species, not only have huge size differences, but also have reproductive isolation.

Of course, Gulu will not name these swollen-headed dragons anymore. He and Mungo can become the sea kings in the sea, and they can name the new species in the sea because they do not live in the sea, and they have no interest in the sea. conflicting.

On land, especially in the continent of Yukan, even though Gulu and Mungo have long been recognized as kings, they still don't care about the affairs of other ethnic groups, let alone naming other ethnic groups.

This battle lasted for a whole afternoon. In this world that speaks with strength, of course, the subfamily with an average weight of 1.5 tons succeeded in having the name Pachycephalosaurus, and other Pachycephalosaur subfamily can no longer use this name. claim to be.

However, if they don't call themselves Pachycephalus, they don't know what to call them, and they gradually dispersed. At worst, they don't need names, mainly because no dragon has the ability to unify the name of a race in a short period of time.

The names of the various dragon races are gradually unified in the long history.

Gulu quickly said: "Gaya, Meng Ge, you have seen that the largest pachycephalosaurus is very powerful, and it will die if you are hit by them. You should pay attention in the future."

Both Meng Ge and Ga Ya kept nodding their heads, and Meng Ge also thought in his heart that he would tell his brothers what he saw today, so that his brothers would also pay attention to this kind of dragon in the future.

After watching this big show, Gulu excitedly said to Ga Ya: "Gaya, Ga Ya, I have great news for you, Mungo and I have our own dragon eggs, which is to turn Mongo into a human." The portable space helped us cultivate..."

Ga Ya was very shocked, but at the same time very happy, she thought, that space can turn Mongo into a human being, and it is not so difficult to understand the dragon eggs that can cultivate Mongo and Gulu.

Originally, Mungo and Gulu didn't have their own cubs, Gaya was very worried, especially Gulu, Triceratops would have cubs.

Ga Ya: "Why didn't you tell me earlier, can you take me to see your dragon eggs now?"

In fact, Ga Ya can also think that Gulu and Mengge chose to tell her now because she is not in good health and cannot travel for a long time. If she is told in advance, she is too anxious to come back to see Mengge and Gulu's dragon eggs. Breaks are ignored.

Mungo and Gulu said in unison: "Of course, we will go now."

The triceratops of the Gulu tribe are not familiar with Gaya, but they all know Gaya, and they also know that Gaya is Gulu's tyrannosaur Mama, and Gaya treats Gulu very well.

Ingaya walked slowly into the group, and the Triceratops of the Gulu group would not be afraid.

Gaya was so happy looking at the nest of big white dragon eggs, and it was great that Mungo and Gollum finally had a cub of their own.

Babana has been taking care of these dragon eggs in Gulu's clan. She is very happy to see Gaya back. Babana has always been very grateful to Gaya. Without Gaya, Gulu would not have been able to survive in the Tyrannosaurus rex clan. down.

Since then, Gaya has been living in Mungo's tribe. She hunts by herself and will not let Mungo's brothers hunt for her.

Just living in the Mungo group, she no longer has to worry about being attacked by a Tyrannosaurus rex that is stronger than her, and can live a very stable and comfortable life, quietly waiting for the birth of the eggs in her stomach.

Now Gaya has only one firm belief, she wants to give birth to these dragon eggs, hatch these dragon eggs, and raise her and Leon's cubs to grow up.

Gaya also often goes to Gulu's clan to see Gulu and Mungo's dragon eggs.

After many pachycephalosaur subfamilies appeared, Gulu thought that he could still see many stegosaurus subfamilies, ceratopsian subfamilies, hadrosaurus subfamilies...but these still appeared in large numbers, at least Gulu didn't see them.

During this period of time, there was a lot of rain, basically one day of heavy rain and one day of sunshine, ferns grew wildly, and the amount of water in the Dada River also grew wildly.

Hatching eggs in the rainy season needs to be very meticulous. Once it starts to rain, the baby eggs must be moved to a place with higher terrain that is not easy to accumulate water. Dragon eggs cannot be soaked in rainwater for a long time.

Gulu and Mungo always look for stone nests on the hills in the territory to incubate the cubs. There are no mountains on the plain, only small hills. There will be some stone nests on these hills, which can just hold a nest of dragon eggs. .

The stone nest is warm and dry, and Mungo and Gulu will use cycad leaves to block the opening of the stone nest, leaving only a small gap for ventilation, and thick ferns will be stuffed behind the gap left to prevent wind and rain from entering the stone nest. The eggs are damp.

During this period, Gulu and Mungo will keep guarding the dragon eggs. There are many rodents on the hill, and they will steal eggs to eat. Only by guarding can Mungo and Gulu rest assured.

In this way, it rained intermittently for half a month.

On this day, the weather suddenly cleared up, and it was sunny for several days in a row.

Gulu knows that there will be another rainstorm after ten days of clear weather at most. At that time, the Dada River will burst its embankment. The flood this time will not be bigger than the one before the migration, but it will submerge part of the fern planting. The safest measure It is better to move to the big mountain at the end of the fern plain in advance.

Mungo has also learned to watch the stars at night, and he agrees with Gulu's prediction very much.

It takes at least 15 days to go to the mountain at the end of the Fern Plant Plain. It is impossible to walk with a dragon egg in its mouth. First, it is not safe to walk for such a long time. Don't worry about handing Baby Egg to other dragons in the group, the journey is too far.

When all dragons migrate or change territories, as long as they have baby eggs, they will be involved in the problem of moving dragon eggs. Gulu and Monggo are the leaders, and they can ask other dragons in the group to help them. Ordinary dragons can only rely on Own.

The safest and safest way to carry the dragon eggs is to slowly sit the dragon eggs in the anus and carry them. The temperature is suitable and very safe. As long as the adult dragon does not die, the dragon eggs are safe. When you want to excrete, then gently Just pull it out and put it back in when you're done.

Of course, Gulu and Mungo can only use this method.

Meng Ge is a carnivorous dragon, and it is a male dragon. The back is very narrow, it is not easy to fit in, and it is not safe to put it in. This is why the male Tyrannosaurus rex cannot hatch dragon eggs.

Tyrannosaurus rex cubs are all raised by the female Tyrannosaurus rex. It is difficult for a male Tyrannosaurus rex to feed the cubs alone, unless it is a cub that has broken its shell. That said, the male Tyrannosaurus rex can easily kill a cub.

All male triceratops can be put in dragon eggs, and Pardo and Babanna have carried dragon eggs in this way before.

It's just that Gulu thought that as a human being, he really couldn't accept this way of transporting dragon eggs.

Gulu wants to put it in the portable space, but the portable space has no temperature, and it can't simulate the hatching environment, so it can't hatch dragon eggs, so Gulu and Mungo need to hatch by themselves.

Putting it in the portable space is also not acceptable.

As a qualified father, Gulu had to come by himself for the absolute safety of the dragon egg.
