Mamenchisaurus Size report

Mamenchisaurus was a large sauropod dinosaur known for its long neck, accounting for almost half of its total body length. Fossils of Mamenchisaurus have been found in several provinces in western China. Mamenchisaurus was the first giant sauropod dinosaur discovered after the founding of China.

Mamenchisaurus's fossil was first discovered in Yibin, Sichuan, China, in 1952. In 1964, the first public exhibition of fossils caused a sensation. Since the 1980s, Mamenchisaurus has become a "dinosaur ambassador" again, and its fossils have been exhibited abroad many times. To this day, Mamenchisaurus is still the most famous Chinese dinosaur worldwide.

Mamenchisaurus not only has the largest number of cervical vertebrae and the longest neck among all dinosaurs but is also one of the largest individuals, the most and best-preserved dinosaur fossils found in the world. Most Mamenchisaurus can exceed 20 meters in length, and a few individuals may exceed 30 meters. The smaller ones weigh under 10 tons, while the largest is likely to exceed 30 tons. This post will share more interesting facts about Mamenchisaurus.

Mamenchisaurus Size and Appearance

In the Late Jurassic, 145 million years ago, it was covered with vast and dense forests, redwood trees growing everywhere, and groups of Mamenchisaurus often crossed the forest. The teeth of Mamenchisaurus were spoon-shaped, which may be more suitable for the vegetation at that time. Mamenchisaurus is the most famous large dinosaur discovered in China. It has a long neck with 17-19 cervical vertebrae, and a strong tail and walks on four pillar-like legs. Mamenchisaurus may seem clumsy and slow-moving, lacking the ability to defend itself, but it has its weapon, the tail hammer that grows at the tail end. The tail of Mamenchisaurus also occupies the other part of the body, and when it is swung, it can emit the power of a cannon for defense.

Average Size of Mamenchisaurus

Mamenchisaurus is one of the largest sauropod dinosaurs discovered in China so far. The length of a standard tennis court is 23.77 meters, and the overall length of Mamenchisaurus reached up to 25 meters, which is unimaginable. The standing height of Mamenchisaurusand is nearly 6-11 meters. Its neck is very long, about 14 meters, which is equivalent to half of the body length. It is the animal with the longest neck that has ever lived on earth. There are many cavities in its spine, so compared to its huge body, the weight of 10-12 tons is not an exaggeration. The typical lifespan of the Mamenchisaurus was between 35-45 years.

Final Words

While not as thickly built as the Apatosaurus or the Argentinosaurus, the Mamenchisaurus' neck was the most impressive, with no less than nineteen huge, elongated vertebrae. Architectural design engineers said that the neck and tail of Mamenchisaurus, together with the body parts, are like a suspension bridge. The spine is like the steel cables of the suspension bridge, supporting the balance of the neck and tail and transferring the weight to the body parts, and the pillar-like legs support the body. With the development of paleontology, more and more dinosaur fossils have been discovered in China, and more and more members of the Mamenchisaurus family have also been discovered.
