1All dinosaurs descended from sauropods.

It is currently believed that the first marine life was born from the thunder synthesis.

They only have one cell, and then genes mutate and more gene types appear, and then the fittest survive and the unsuitable ones are eliminated.

Later marine vertebrate plants crawled ashore from the sea.

These plants dominated the world before the age of dinosaurs, including Dimetrodon.

3 Living in the Triassic period about 270 million years ago, Heteroptera animals had long fins on their backs, about 3.3 meters long, and their backs were covered with scales.

In order to catch prey, speed is particularly important.

The tail acted as a balancer by holding up the body with the forelimbs, and the entire body was hinged on the belt, developing into a dinosaur with a special reptilian form.

At the end of the Triassic, the environment improved and most species became extinct.

In order to conform to the a priori environment, the organism begins to degenerate again.
