Mamenxisaurus is very similar in appearance to another famous dinosaur, Brontosaurus, with the only difference being the length of the neck. They can reach neck lengths of up to 46 feet (about meters), which is half the total length of their bodies. Mamenxisaurus was a herbivorous dinosaur that lived hundreds of millions of years ago.
The Mamenxi dragon has the longest neck in the world, and if it is compared to a giraffe, the giraffe will lose badly, with a total neck of 11-14 meters. The neck of the dragon was supported by long, overlapping cervical vertebrae, which made it stiff and rotated very slowly. The muscles in its neck are quite strong, supporting its small snake-like head.
It has many hollows in its vertebrae, making its head small compared to its massive size. 145 million years ago, dinosaurs lived in a vast, dense forest filled with redwood and redwood trees. Herds of Mamenxi dragons made their way through the forest, using their small, nail-like teeth to nibble on leaves and twigs from tree tops that other dinosaurs couldn't reach.

Very long neck, the neck takes up almost half of the total length of the body.
Mamenxisaurus is a genus of sauropods that is known for its very long neck, which accounts for almost half of the total length of the body. There are several species that have been classified into the genus Mamenxisaurus, and the attribution of individual species may be disputed.
Its fossils have been found in several provinces in western China. It is closely related to Emeisaurus and belongs to the Mamenxi dragon family. Most Mamenxi dragons were more than 20 meters long, and a few individuals could exceed 30 meters.
Estimates of the weight of Mamenxisaurus vary greatly between species, with smaller species thought to weigh less than 10 tonnes, while the largest species are thought to have weighed more than 60 tonnes.
Mamenxisaurus was first discovered in 1952 on the construction site of the Yitang Highway in Sichuan Province, China. The fossil site belongs to the Shangshaxi Temple Formation, which dates back to at least the Late Jurassic. In 1954, Yang Zhongjian, a famous Chinese paleontologist, studied this part of the skeleton fossil and named it Mamenxisaurus.
The orthotype specimen is incomplete and disorganized. Materials include: 5 dorsal vertebrae, 30 caudal vertebrae, rib scarf fragments, dorsal nerve spines, and pulse arcs. There were 14 cervical vertebrae, but none of them were intact, and Yang noted that some cervical vertebrae may have been lost and estimated the entire neck to be meters.
There are also some limb bones, including: two femurs, a complete tibia, fibula, talus, metatarsals, phalanges, and claws. The skull, forelimbs, and belt were not preserved. It is estimated that the length of the construction of Mamenxi Dragon is about 13 to 15 meters with a mass of 5 tons.

The bones are real, and the restoration is speculative, after all, the dragon has been dead for 65 million years. Who knows what it really looks like.

Mamenxisaurus lived in the late Jurassic period 100 million years ago. At that time, the area where it lived was covered with dense woods, with conifers and ferns growing everywhere. As it travels through the woods, it uses its nail-like teeth to nibble on leaves.
However, it can eat the young leaves of tall trees, thanks to its long neck.
Normally, it is mainly on four legs, with the tail straight to keep the body balanced. If it is during the mating season, they will attack each other with their tails, and when they encounter strong enemies, their tails will become ** again, attacking enemies.
