In Patagonia, found the remains of the largest dinosaur ever
• In Patagonia found the remains of the largest dinosaur in the history of
Scientists have officially confirmed that they found in the Patagonian dinosaur epic proportions is the largest land animals in Earth's history. Imagine a standard swimming pool or seven elephants facing each other - these are the dimensions of the ancient giants, which are attributed to a new species Patagotitan mayorum. As for weight, it is quite a bit did not reach the weight of a small space probe.
Dinosaur first discovered shepherd Aurelio Hernandez on the Patagonian ranch La flehi in 2012. The rancher called to paleontologists, and after 18 months, they unearthed bones - as it turned out, the remains of six young dinosaurs.
All six individuals were recovered from three geological layers: probably the fact that they all died at the lake, where they and other herbivorous dinosaurs come to drink. Perhaps in times of drought the lake dries up and the dinosaurs died off its coast from thirst. And dinosaurs carrion, eats the remains of dead animals, their bones trampled deep into the clay, and that has contributed to the preservation.
The fossils included vertebrae and ribs of dinosaurs, which attributed to a new species Patagotitan mayorum. Its representatives weighed an average of about 62-69 tons, and their length from head to tail is more than 35 meters, six of which had neck. And it is likely that this is not the limit, because in adulthood, these individuals can achieve even larger sizes.
The ancient giants surpassed the length of all known terrestrial animals - both extinct and modern. Their weight was greater than the mass of some modifications "737".

"Probably, it was a massive slow-moving animals. Tyrannosaurs looked dwarfed by these dinosaurs. It's like comparing a lion and an elephant "- said one researcher Diego Pol.
Reconstruction Patagotitan mayorum
Ancient giant herbivore Patagotitan mayorum lived during the Mesozoic, about 100 thousand years ago. Most likely, this gigantism extreme only once appeared in the course of evolution. All whopping titanosaurs lived only in the interval 113-83 million years ago in the south of present-day South America. Probably long necks and tails of lizards help them withstand unusually hot temperature, characteristic for that period.

Nakhodka so impressed the scientists of the National Research Council (Argentina) that they gave a skeleton American Museum of Natural History, where he was put up in 2016, when a new kind of have not even got a name.
