Mamenchisaurus

Mamenchisaurus

Mamenchisaurus was a genus of dinosaurs that was on our planet during the Jurassic period (about 156 million years ago). This genus has been classified among the group of sauropod Mamenquisaurid dinosaurs.

This genre would have been a really big size, ranging from 16 to 25 meters in length. As is common in large dinosaurs, it fed simply on vegetation, i.e. it was a herbivorous dinosaur.

The Mamenchisaurus would have had a neck very similar to that of the Diplodocus, being a really light neck. The length of his neck was really long and is the reason why he was able to survive by being able to reach more vegetation than other smaller herbivorous dinosaurs.

Its official name has the following significance: Reptile of Mamenchi. Meanwhile, it can be said that the length of the animal could be up to a total of 25 meters, which was not a smaller size.

Although it has also been possible to observe the presence of other specimens of the same genus as a smaller dimension, although several of them had a total length of 16 meters, it is nevertheless one of the rare specimens of the largest lengths we have ever been able to have.

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 true immensity, on the other hand, its weight could have been around 27 tons.

As for their legs, in summary, we can argue that the extremities of the front area did not enjoy the prolonged size of the extremities in the rear area.

The discovery turned out to be very simple, precisely in the area near a place where a series of constructions and repairs were being made to what we often know as a “ferry”, in a village 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 remains found within a formation known as Shangshaximiao, in which only a bone structure that was incomplete could be found.

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 take place, a new set of vestiges were to be found in the Hantong formation.

However, everything was more interesting after approximately 20 years, exactly two years after the beginning of the 1970s, when in the same formation that we mentioned in the first place, that is to say, in the Shangshaximiao, it was possible to locate a group of no smaller vestiges.

They 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.

In addition to all this, it took another twenty years for new efforts to locate another set of remains, precisely in 1993, traces of a new species belonging to this genus were obtained. However, this new animal turned out to be much more robust, whose bony elements also presented these qualities, especially in the rib area, which were much thicker.

Three years after this discovery, another specimen was found, a structure that has greatly helped to learn 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 redwood forests, which were full of plants and leaves ready to become the food of the specimen.

It is also known that this specimen may have lived in medium sized groups, very similar to what we see today in animals such as sheep, which form herds and follow common behavior, sheep that are also dedicated to the consumption of vegetables at ground level today, so it goes without saying that this animal was a herbivore.

Feeding of the Mamenchisaurus
On the dental structure of the Mamenchisaurus, you can see that these elements were shaped like studs, in other words, they were elements that were designed almost perfectly to perform the function of extraction of leaves located in trees or shrubs, this creature did not need too much force to pull out these vegetables, because their teeth made it easier.
