Flying dinosaurs, as soon as the name is mentioned, everyone can't help but think of pterosaurs, yes, almost all flying dinosaurs are pterosaurs, but pterosaurs are also divided into many species, just like birds, birds are divided into many types.

There are more than 100 species of pterosaurs, large and small, and there are countless of them, among which the small ones are almost the size of a dog, but the big ones are surprisingly large, such as the Aeolian Pterodactyl.

Fengshen pterosaur was born in the late Cretaceous period, its wings can be 11 meters long, it is the largest pterosaur, and it usually feeds on small dinosaurs.

Song Zihang picked up his cloning materials and looked at them from beginning to end, cultivated the DNA of the Fengshen pterosaur, and then successfully cloned a small Fengshen pterosaur.

As soon as this Fengshen pterosaur was taken out, it was only the size of an eagle, but it was fierce by nature, and when it came out, it ate several chicken thighs, and it grew very fast, and it could grow to the size of three or four meters soon.

Song Zihang cloned three Fengshen pterosaurs at once, the same male and two female, in order to let the Fengshen pterosaurs settle down with peace of mind, Song Zihang also used some small means, such as leveling mountains in the ecological park, and directly made a cliff several hundred meters high.

The habits of the Fengshen pterosaur are quite similar to ordinary eagles, and they like to build a nest on the cliff, and they are also afraid that the Fengshen pterosaur will fly out, Song Zihang's also arranged a vacuum zone above the enchantment, and there is no oxygen in that position, and the Fengshen pterosaur flies there, and when it can't breathe, it will naturally fly down.

Song Zihang released the Fengshen pterosaur and looked at the ecological park that was relatively complete, and now there are herbivorous dinosaurs Triceratops, Ankylosaurus, Stegosaurus, and Diplodocus in the entire ecological park.

Carnivorous dinosaurs have Tyrannosaurus rex, and those that can fly have Aeolian pterosaurs, so what is missing now, it seems that there are probably several small dinosaurs missing.

Song Zihang thought about this for a while, and looked at the four dinosaur genes in his hand that had not been cloned, and now that it had reached this point, how could Song Zihang let go of the remaining four dinosaur genes.

Thinking of this, Song Zihang began to study and clone again, and cloned three dinosaurs of the remaining four dinosaurs at once, these three dinosaurs are not too big, and they all belong to the small dinosaur series.

Among them like the microraptor, at this time a little guy with feathers similar to birds, his favorite thing is to steal dinosaur eggs, in order to raise him Song Zihang specially went to the African savannah to get back a batch of ostriches, the ostrich eggs are big enough, enough for these little guys to eat, as for the eggs of other dinosaurs, Song Zihang decided to protect them strictly, but he can't let this little thief get his hands on it, otherwise he will let this little guy break the ecological park after all his hard work.

However, although the microraptor is very bad, he can also find his natural enemies, such as the fierce Allosaurus, Allosaurus is also a member of the small man series, but it is actually not too small, it can generally grow to five or six meters long, although it cannot be compared with the behemoth Tyrannosaurus rex, but it is also a seed player among carnivorous dinosaurs.

And Allosaurus is known for its speed, if you compare it with the animals in nature now, I think this Allosaurus is equivalent to the cheetah in nature now.

It has a terrifying speed, and at the same time, in addition to Allosaurus, there is also a carnivorous dinosaur in this small army, that is, Dinosaurus.

Dinosaurus is a relatively small dinosaur in the army of small people, with a body length of about three meters, and there is no way to compare it with Allosaurus, let alone a horror like Tyrannosaurus rex.

Dinosaurs belonged to the dinosaurs that walked upright, and their most powerful weapon was not the sharp teeth in their mouths, but the long, thick, large, and sharp claws on their two short forelimbs.

In predation, dinosaurs like to attack in groups, together with their sharp claws on the back of the prey to scratch out a wound, and then keep driving away the prey, the prey will die because of a lot of bleeding, then a group of dinosaurs pounced again, a burst of operation to eat the prey.

This kind of team crime, and ruthless style, if you have to find the current animal to sit down, I'm afraid only wolves can be compared with it, this dinosaur hunting method, and intelligence is actually even Tyrannosaurus rex is difficult to achieve, after all, the clumsy Tyrannosaurus rex due to its overwhelming strength, rarely use their brains to think of some way to hunt other dinosaurs, their most common method is to rush over, knock down the prey, and then tear the fragile belly of the prey, take out the internal organs of the prey, and eat the prey.

Simple and rude, extremely efficient, and the reason for this is to rely on the invincible physical fitness of the Tyrannosaurus rex, if this series of actions is replaced by a dinosaur, it is estimated that the scene will be very tragic, relying on the small physique of the dinosaur, a head hit the body of the triceratops, no need to think about being abused by blood.

So dinosaurs had to live in groups, they had to be as fierce as hungry wolves, united as one, and hunt their prey.

Microraptor, dinosaur, Allosaurus, this is the small and medium-sized dinosaur cloned by Song Zihang, of course, there is another dinosaur that is not cloned, this is Spinosaurus.

The reason why Song Zihang did not clone the Spinosaurus was because Song Zihang found that the positioning of this dinosaur was wrong, Spinosaurus was probably not a small dinosaur, on the contrary, this was likely to be a large carnivorous dinosaur, which made Song Zihang hesitate, after all, there are already large predators like Tyrannosaurus rex in this ecological park, and if you rush to clone a large carnivorous dinosaur, will it lead to the rupture of the food chain of the entire ecological park, which will lead to the loss of competitiveness of the entire ecological chain, This is a factor that can easily lead to the imbalance of the entire ecological park!

Song Zihang thought about it for a long time, and finally decided to resign himself to fate, in order not to cause the entire ecological park to break, he could also introduce some large herbivores such as cattle and sheep as food for these predatory dinosaurs.

Thinking of this, Song Zihang started the machine and prepared to clone Spinosaurus.

Spinosaurus is a large carnivore, huge, can grow up to 12 meters long, is a powerful existence that can fight with Tyrannosaurus rex, and the most characteristic of Spinosaurus is his back, it is a dinosaur that walks around with a sailboat on its back, its back is high and bulging, as if carrying a huge sail.

Spinosaurus was very large, so after cloning the three, Song Zihang gave Spinosaurus the same treatment as Tyrannosaurus Rex, that is, dividing the area separately and feeding artificially to ensure that Spinosaurus was not hungry, it can be said that Song Zihang maintained these dinosaurs very well.

But just after a month, Song Zihang found a problem.
