The Mamenchisaurus was a genus of dinosaurs that was on our planet during the so-called Jurassic period (about 156 million years ago). This genus has been classified within the group of the sauropod dinosaurs mamenquisaurids.
This genus would have had a really big size, ranging from 16 to 25 meters long. As it is common for large-sized dinosaurs, it simply fed on vegetation, that is, it was a herbivorous dinosaur.
The Mamenchisaurus would have had a neck very similar to the Diplodocus, being a really light neck. The length of its neck was really long and that is the reason why it could survive by being able to reach more vegetation than other smaller herbivorous dinosaurs.

Discovery of Mamenchisaurus
Its official name has the following significance: Reptile of Mamenchi. Meanwhile, it can be stated that the length of the animal could have been a total of 25 meters, which was not a minor size.
Although it has also been possible to observe the presence of other specimens of the same genus that were smaller in size, several of which had a total length of 16 meters, nevertheless it is one of the rare specimens of the longest lengths that we have been able to have in history.
The interesting thing is that at the time when their great discovery was made, traces were obtained that did not really complete the entire bone structure of the animal, so a group of scientists came to the conclusion that it was a creature of smaller dimensions, unaware at the time that they were falling into one of the biggest mistakes of their careers.
After a few years other important findings could be made and finally the size of the animal could be closer to reality, it was not based on simple and easy assumptions of what it could have been, but it was studied in detail and all the vestiges that this specimen had left were analyzed and interpreted.
One of the most important areas of this creature called Mamenchisaurus was the neck, which could even have a total of 19 vertebral elements, a real immensity, on the other hand, its weight could have been around 27 tons.
As for its legs, in summary, we can argue that the extremities in the front zone did not enjoy the prolonged size that the extremities located in the rear zone had.
The discovery turned out to be very simple, precisely in the area adjacent to a place where a series of constructions and repairs to what we frequently know as “ferry” were being carried out, in a town called Sichuan, in China.
All this was carried out precisely two years after the beginning of the 1950s, precisely in the middle of the last century, and the vestiges found inside a formation mostly known as Shangshaximiao, in which it was only possible to locate a bone structure that was incomplete.
This bone structure was reviewed by a famous scientist from the same country, two years after the discovery, who also showed that he was really surprised by the large size of the specimen, which at that time was more than 20 meters long.
A little later, another important discovery was to be made, a new set of remains to be found in the Hantong Formation.
However, everything became more interesting after about 20 years, exactly two years after the beginning of the 1970s, when in the same formation we mentioned first, that is, in the Shangshaximiao, a not lesser group of vestiges were located.
These belonged to up to four different individuals. Such an important discovery had not been made in that place, so it became the most important scientific news of that time.
Comparison with another animal
One of the structures of these dinosaurs had a neck measuring up to 10 meters long, while its weight was around 50 tons, however, by that time there was another specimen with a giant neck as well.
A different specimen that had been discovered in American territory, precisely in a territory that today belongs to the United States of America, the giant Sauroposeidon, without forgetting to mention another one that would later be pointed out as an animal with a huge neck too, the fearsome Supersaurus.
Both animals mentioned also had a neck of elongated quality, the first one that was mentioned had a neck of about 12 meters, while the second one was 2 meters longer than the previous one, so the dinosaur protagonist of this article was finally surpassed in length, although just barely.
In addition to all this, another twenty years were needed for new efforts to locate another set of remains, precisely in 1993 it was obtained traces of a new species that belongs to this genus, however, this new animal proved to be much more robust, whose bone elements also had these qualities, especially in the area of the ribs, which were much thicker.
Three years after this discovery, another specimen was found, a structure that has helped a lot to know more details and data about this mysterious specimen.
About the environment in which this animal developed its fruitful existence, we can say with total certainty that this environment was quite favorable, since there was a deep and abundant vegetation, among which we can mention the famous sequoia forests, which were full of plants and leaves ready to become the specimen’s food.
It is also known that this specimen could have lived in medium size groups, very similar to what we see today in animals such as sheep, which form herds and follow a common behavior, sheep that also today are dedicated to the consumption of vegetables at ground level, so it goes without saying that this animal was a herbivore.
About the dental structure of the Mamenchisaurus, it can be observed that these elements were shaped like a tack, in other words, they were elements that were designed almost perfectly so that they can fulfill the function of extracting the leaves located in trees or bushes, this creature did not need much strength to be able to pull up these vegetables, since its teeth made its job easier.
