In the Lower Cretaceous Asia lived the dinosaur Wuerhosaurus, in the Mesozoic era, about 140-130 million years ago. It belongs to the category of armor dinosaurs and is one of the few representatives of this group that survived until the period of the Lower Cretaceous.
The skeleton of this interesting prehistoric animal was discovered on the territory of present-day China, in the province of Xinjiang, and in 1973 it was described by Chinese paleontologist Dong Zhiming and named wuerhosaurus homheni.
The giant dinosaur apparently reached a length of 6-8 m and weighed 4 tons, as the researchers estimated, lived in wooded areas and fed on large quantities of plants. On the back of his sturdy body stretched a double row of plates, of square shape, which on the middle of the back were very large and became smaller and smaller towards the tail and neck respectively.The tail was thick at the base and thin towards the tip, and at its end were two pairs of thick spines with sharp tips, like Bone Spikes, which could cause very serious injuries to opponents.
His head was extraordinarily small compared to the size of his body; the cranial box housed a small brain the size of a walnut. Large orbits indicate that this animal had good eyesight, the Horn beak was devoid of teeth, and on the sides of the jaws it had rather poorly developed masses.
Having a special bone structure of the vertebrae in his neck, he had the ability to hold his neck in a horizontal position, and his head lowered it close to the ground, being always concerned with the search for food. His gait was on all four muscular limbs, long and strong, which managed to support the entire weight of the body, balanced by the long and rigid tail.
When in danger, Wuerhosaurus used to raise its flexible tail with thorns in front of the predator and defend itself with the help of armor on its back from blows and bites.
The dinosaur Wuerhosaurus belongs to the order Ornithischia, family Stegosauridae. This family includes another species called Wuerhosaurus ordosensis whose length has been estimated at only 4 m and weight at 1.2 tons. Its fossil remains were discovered by the same researcher Dong Zhiming in 1993 in the Ordos plateau in Mangolia.
