The Water Dragon, an extinct mammal-like reptile. The head is large, the neck is short, and the body is barrel-shaped. The body shape was somewhat similar to today's hippopotamus. It is characterized by a significant downward curvature of the face, so the skull is high. The nose is very high, all the way down to the eyehole, the body structure has a number of mammalian progressive traits, but the head is still primitive, living on the edge of lakes and swamps, living as a plant in the late Permian to the early Triassic, about 250 million years ago, is an extremely ancient creature.

The Water Dragon lived in the early Triassic period of earth history about 200 million years ago. It is widely distributed in South Africa, India, Antarctica, and all the way to Xinjiang, China. Fossils found on various continents are so similar that they all belong to the same genus, and some can even be attributed to the same species. The Dracosus is often used as evidence of continental drift , proving that continents were interconnected 200 million years ago , and it is considered by many scientists to be the ancestor of all mammals on Earth — and therefore the ancestor of humans.

The water dragon is about a meter long and is about the size of a modern dog. The most obvious feature is that the upper jaw is equivalent to a pair of tusks in the canine tooth area, and there are no other teeth. Compared to other heterodonts, the skull structure of the water dragon is more peculiar. Its orbital position is very high, reaching the top of the head, and the face and snout in front of the orbit do not extend forward like other groups, but fold downwards, forming an angle between the face and the top of the head, which can sometimes reach 90 degrees. At the same time, the position of the nostrils is also moved to the underside of the orbit.
The fossils preserved with the water dragon also contain many terrestrial creatures. All of this proves that the Water Dragon beast is most likely a completely terrestrial animal. They also proposed that the water dragon beast dig a cave for itself. Of course, these conclusions need to be further studied on the bones behind the head to confirm. However, for now, it seems that the name of the water dragon beast may be a historical misunderstanding, because it does not live in water.
65 million years ago, the earth was ruled by dinosaurs. However, British scientists claim that the prehistoric earth was once dominated by a group of animals called "water dragons". According to scientists at the University of Leeds in the United Kingdom, this prehistoric biology similar in size to modern pigs is called the "Water Dragon", which ruled the earth 260 million years ago.
Scientists say that before the arrival of the "Water Dragon Age", the earth suffered a mass extinction disaster, 95% of the earth's life was extinct in a series of volcanic eruptions, but these "water dragon beasts" survived, spending at least 1 million years on the plant-rich earth without any natural enemies and predators in the "golden age".
Scientists say the water dragons are similar in size to modern pigs, with pig-like beaks and small fangs that allow them to dig up vegetation on the ground. The Dracos are considered by many scientists to be the ancestors of all mammals on Earth – and therefore human beings. These "prehistoric pigs" bred on Earth for at least 1 million years, and finally as the Earth's climate changed, dinosaurs began to appear and take over the planet.
