If you want to see an animal with a demonstrably longest neck, you would have to travel by machine in time and to the middle of Jurassic.
As is well known at the time, the sauropod dinosaurs had the longest necks among the well-known vertebrates in the life of life on Earth. In this respect, they were somewhat similar to the plesiosaui reptiles, their unrelated Mesozoic contemporaries, but otherwise the land or mosquito was not close to them (which also applies to contemporary iraffs with a maximum neck length of about 2.4 meters).
Paleontologists still do not know which of the hitherto known sauropods could have had a neck, in which the genera Mamenchisaurus (in the problematic species M. sinocanadorum about 12 meters), Supersaurus (and 15 meters) and Barosaurus (and 17 meters) are especially important.
However, due to the incomplete fossil material, we can only estimate the length of the neck of these two figures very roughly. And so he does not have to turn his attention to the longest surviving crown in the fossil record and find out the length of the neck with a sufficient degree of certainty.
A giant with a long neck
Although the name of its owner does not say much to it, the mare itself is impressive enough to correct its decoration and the appearance. So who is the current record holder in terms of neck length? Like the mentioned mamenchisaurus, this dinosaur also came from the land of the day, where it was only a few million years old (similar to the Middle Jury, v kelloway, about 164.6 million years ago).
Fossils of this mamenchisaurida were discovered in 2012 in the sediments of the geological formation of Qiketai on the ground of Xinjiang Province in the northwestern part of the north. A year later, according to hitherto estimated, the giant was about 27 and 32 meters and between 25 and 40 tons formally described as Xinjiangtitan shanshanensis (literally Titn from Sin-iang, coming from the anan area).
The size of this dinosaur is evidenced, for example, by the thoracic vertebrae, reaching a length of 372 cm, a very robust femur 165 cm long or a tibia 98 cm long. But how long was the neck of this imposing Asian sauropod? This question was discussed in detail by the paleontologist Matthew Wedel on the popular SVPOW website in January this year.
It shows the exact dimensions and orientations of the individual skeletal centers, including the cervical vertebrae. The body of the cervical vertebra did not work (specifically twelve vertebrae) with a length of four centuries of 123 centimeters, which of the sauropod vertebrae has not yet been discovered.
Piblin size and shape of tla mamenchisauridnho sauropoda species Xinjiangtitan shanshanensis. At a length of about 30 meters, this villa has about 25 and 40 tons. His neck with a minimum length of 13.4 meters is probably the longest confirmed neck in all known animals. Some sauropods may have had this pressure a few meters long, but the bottom of them did not retain enough complete red cervix.
The integrity of some skeletal sites was re-evaluated in the new study, and overall the fossils of the lp were prepared and reconstructed. As a result, a total of 18 spinal vertebrae were introduced, forming an essentially unpersulated articulated whole. Ten vertebrae had a light length of less than 1 meter, and if we were to think of the cartilaginous surrounding tissue, then we would have to estimate the neck length of the num mamenchisaurida at 15.1 meters!
At least one length, corresponding to the tightly connected vertebrae, then in exactly 13.36 meters. And that’s the length of a bus or three cars in a row. The total length of the xinjiangtitan pressure is estimated by Wedel at 33.55 meters, although he states that, paradoxically, it was a slightly stately sauropod who was large enough for his skeleton to fossilize whole.
It is important that due to the relatively high completeness of the fossil of the type specimen of the genus Xinjiangtitan, we can quite accurately estimate the minimum length of its neck. And that’s at least 13.4 meters, which is the absolute record in life and in all periods of life on the planet. For the sake of completeness, we can add that he put in order that all completely preserved crowns of sauropods are the one described by nation paleontologists in Mamenchisaurus hochuanensis (9.5 meters) in 1972, and this imaginary furnace is Giraffatitan brancai with a neck length of 8, 5 meters.
It is practically certain that some Sauropods should have a substantial part of their neck, as evidenced by the 137 cm long vertebrae, the foot of an enormously large diplodokid of the genus Supersaurus or Barosaurus.
But we return to the Xinjiangosaurus genus. This ob sauropod undoubtedly had an enormously long neck, but otherwise fell into the medium size category, and the weight of the titanosaurm did not even increase. Thanks to his neck, Pesto could be one of the tallest dinosaurs, his head was in the range of about 17 meters.
This mamenchisauride has apparently used its impressive age to make a letter in everything high above the ground, where its food competitors simply did not reach. We hope to learn more about these fantastic Jurassic sauropods in the future.
