Before migrating, the Allosaurus herd had to be fed enough to ensure that they could starve for a while if they could not find prey on the way. Zhang Jun found that he could go without food for a month at most, and other Allosaurus estimates are similar.

After staying in the dragon group for a long time, Zhang Jun also found that their social surnames had been initially formed, and there were certain social relations, indicating that they were indeed a relatively intelligent species.

Among the other eight Allosaurus, most of them are friendly to Zhang Jun and get along with him, but there is one big guy who is not very friendly to Zhang Jun, and it is a male dragon that is not much different in size from the leader dragon, and like Zhang Jun, it is one of the seven male dragons here.

Because Zhang Jun is very fast and powerful every time he hunts, he grasps the timing of his shot better than any dinosaur, and can play a great role, and the leader dragon is very satisfied with Zhang Jun's performance and takes good care of him.

Moreover, the little Allosaurus that appeared in this jungle seemed to be the offspring of the leader dragon, because the two tall female dragons in the dragon group were its own ladies, and the rest of the Allosaurus were not allowed to touch them.

When the female dragon is pregnant, she will lay her eggs in a hidden location in the jungle, bury the eggs with mounds, and cover them with some vegetation such as weeds as a camouflage.

Normally, the female dragon will personally guard the hatching of dragon eggs, but sometimes the environment sometimes forces them to leave early, and not every dinosaur mother will guard the egg hatching, many female dragons are after laying eggs, and then leave to hunt, and the baby dragon is won by numbers, and about 90% of them cannot survive.

Because this jungle is the territory occupied by the leader dragon for a long time, and no other pregnant female dragon will lay eggs here, so Zhang Jun can basically determine that the leader dragon is actually his father, maybe the leader dragon has already been aware of this, and he did not reject him at the beginning, and Zhang Jun can't judge which one his mother is.

Zhang Jun called the unfriendly dinosaur 'villain', it found that the villain is also very strong, second only to the leader dragon in the dragon group, this guy is a little dishonest, once harassed a female dragon, was warned by the leader dragon, but it seems to have been dissatisfied, it recently saw that the leader dragon took good care of Zhang Jun, every time he ate meat, he was allowed to eat a little more, and he was quite dissatisfied.

Zhang Jun has always kept his distance from the villains, and he began to have a relationship with the Allosaurus group, and began to have a good relationship with two small dinosaurs, he was not sure if they were his own brothers, but he felt very close.

According to the memory of later science and education films, Zhang Jun named one of the more agile Allosaurus Big El, and the other one was called Little El, and he also got the favor of one of the largest female dragons, that is, the mother of Big Al and Little El, by having a good relationship with Big Al and Little El.

For other Allosaurus, Zhang Jun often expressed friendship with them, and the relationship study learned in human society is actually useful in dinosaur society. These savage guys are actually surnamed Love Dragons, as long as you approach them with a friendly attitude, they will feel that you are a friend, they will not be defensive of you, and their thinking is very simple.

On this day, the lead dragon finally let out a few low chirps towards the other side of the river, and then nodded a few times, which is the social language of dinosaurs, meaning that it will lead the dragons across the river.

The rest of the Allosaurus understood this simple language of social communication, and they rose from the ground and looked out at the dense jungle on the other side of the river, where the vegetation was much better dehydrated than here, and the vegetation continued to flourish.

Before leaving, the leader led the group of dragons in the direction of a river beach, where the group of diplodocus dragons often haunted, and it was a good place for them to hunt, but in the last six months, the number of dinosaurs has gradually decreased.

After passing through the dense jungle, the vegetation on the surface became more and more sparse, revealing large areas of dust, and before the Allosaurus group approached the river beach, they had already lost their cover and were completely exposed, so they had to rely on the terrain to slowly and carefully approach the river beach.

When I arrived a few hundred meters away from the river beach, I saw that there were indeed a few Diplodocus drinking water on the river beach, but the number was reduced by half compared to before, and there were only three large Diplodocus.

The leader dragon was a little disappointed, because these big guys were so difficult to deal with, their necks were very high, and it was quite difficult to bite the deadly trachea, and without the small diplodocus, their hunting success rate was extremely low, and it was almost impossible to complete the task. Moreover, the vegetation near the river beach has become much lower at this time, and they will soon be exposed, and the few Diplodocus will flee when they notice it.

The battle-hardened leader knew that it could not let any members of the group get hurt until it migrated, and that it had to maintain its population, otherwise it would be weakened on the other side of the river, and it might be overwhelmed by the danger.

The leader dragon immediately made the decision to wait patiently, and then the dragon group remained in ambush near the river beach, waiting for the right opportunity, but the first day passed, and nothing was gained.

Then the second and third days passed, and the dragons still did not find a suitable hunting target, but occasionally encountered some small reptiles nearby, and after being caught by them, it was not enough for a dragon to plug between the teeth, and then the medium-sized hunting object never appeared.

Zhang Jun guessed that the vegetation here has decreased, not as lush as before, so the willingness of the Diplodocus group to reproduce offspring has decreased, and they will not let their offspring be born in the face of the arid jungle environment, so that the Diplodocus cannot survive at all, which is estimated to be the instinct of animals, in the unsuitable season and environment, they will not easily reproduce offspring, perhaps the reduction in food has also affected the hormone levels in their bodies.

Five or six days have passed, and the three-meter-long Diplodocus that the dragon group had hunted ten days ago has already been almost digested by the gastric juice, and they are beginning to feel a little hungry, and it is time for the dragon to make a decision.

After waiting hopelessly, the leader decided not to wait any longer, because there were few animals that came to drink every day, and no other small dinosaurs survived except for the large diplodocus.

This river beach is covered with loess, the width of the river is about 100 meters, the river is deep, there are dinosaurs infested in it, it seems that there should be plesiosaurs and other marine reptiles, but Zhang Jun has not seen it with his own eyes, because he does not know whether this river is connected to the sea.

Once on the riverbank, the dragon wandered back and forth on the riverbank, making a low voice as it estimated how dangerous the river was.

The leader dragon is a person who has come over, it once crossed a river with the dragon group when it was young, and they paid a heavy price for crossing the river, the old leader dragon was dragged underwater by the dinosaur lurking in the river, and the team lost a total of three dinosaurs, and the leader dragon was one of the survivors.

As predators at the top of the food chain, the lead dragon is not afraid of any threat from land, but it is helpless against the dangers hidden underwater, and the lack of food forces them to cross rivers in search of food.
