Seven thousand years ago, the earth continent was ruled by Tyrannosaurus Rex. Its huge body and sharp teeth were extremely terrible. On the other side of the earth, there is a more terrible creature, black dragon. Let's follow the watermelon video creator? Science trip? Look at this overlord in the sea.

Black dragon's ancestors were lizards who lived on the coast 8,000 years ago, and their body length was less than one meter. The land ruler at that time was Tyrannosaurus Rex. It is difficult for such a weak cliff lizard to survive, so it was forced to escape from the familiar land and escape to the ocean to survive.

At first, they only foraged in shallow water, but over time, they gradually adapted to life in the sea, their toes began to evolve into webbed feet, and their bodies evolved into long cylinders with high fluid mechanics. After millions of years of evolution, the little lizard has become a new generation of Neptune overlord black dragon.

Besides swimming very fast, its hearing is also very sensitive. A group of nerves on the side of the maxilla and snout enable them to feel very subtle water pressure waves, so that they can judge the position of distant prey in this way and then hunt.

According to the most fossil studies, black dragon also had a mouth of 1.6 meters, and its teeth were huge conical, bent inward into hooks, enough to crush any marine life at that time. In the 100,000 years after the black dragon appeared, he gradually wiped out many creatures in the ocean, even his own kind. It was with such savage fighting power that they quickly became the absolute rulers in the Cretaceous ocean.

The sudden asteroid hit the earth, and the powerful impact caused a violent earthquake, and hot magma spewed out. In the next ten years, a lot of dust covered the sky, and the whole earth fell into darkness, including the vast majority of creatures on land and in the sea, completely ending their evolution.

It took six million years from the weak cliff lizard to the blue dragon that ruled the whole ocean. However, even the most powerful creatures cannot escape their fate. The magic of life evolution is that you never know what will happen tomorrow. Imagine that if there were no asteroid impact, the earth might still be ruled by dinosaurs today.
