Dinosaur fossils could belong to the world's largest ever creature

전문가들은 아르헨티나에서 거대한 공룡의 유해를 발견했습니다, 지구를 걸었던 가장 큰 생물 중 하나 일 수 있다고 믿습니다.

고생물학 자들은 화석화 된 유물을 발견했습니다. 98 million-year-old titanosaur in Neuquén Province in Argentina’s northwest Patagonia, in thick, sedimentary deposits known as the Candeleros Formation.
그만큼 24 vertebrae of the tail and elements of the pelvic and pectoral girdle discovered are thought to belong to a titanosaur, a diverse group of sauropod dinosaurs, characterized by their large size, a long neck and tail, and four-legged stance.
In research published in the journal Cretaceous Research, experts say they believe the creature to beone of the largest sauropods ever foundand could exceed the size of a Patagotitan, a species which lived 100 백만에서 95 million years ago and measured up to a staggering 37.2 미터 (122 피트) 긴.
It is a huge dinosaur, but we expect to find much more of the skeleton in future field trips, so we’ll have the possibility to address with confidence how really big it was,” Alejandro Otero, a paleontologist with Argentina’s Museo de La Plata, told CNN via email.
Titanosaur fossils have been found on all continents except Antarctica. But the biggestmulti-tonvarieties of the speciesincluding those titanosaurs exceeding 40 tonshave mostly been discovered in Patagonia.
Without analyzing the dinosaur’s humerus or femur, experts say it is not yet possible to say how much the creature weighs. 하나, the partially recovered dinosaurcan be considered one of the largest titanosaurs,” experts said, with a probable body mass exceeding or comparable to that of a Patagotitan or Argentinosaurus.
The newly discovered dinosaur is thought to have a body mass exceeding or comparable to an Argentinosaurus, which measured up to 40 meters and weighed up to 110 tons.

Patagotitans may have been the world’s largest terrestrial animal of all time, and weighed up to 77 tons, while Argentinosaurus were similarly gargantuan, and measured up to 40 미터 (131 피트) and weighed up to 110 tonsweighing more than 12 times more than an African elephant (까지 9 tons).
Experts believe that the specimen strongly suggests the co-existence of larger titanosaurs together with medium-sized titanosaurs and small-sized rebbachisaurids at the beginning of the Late Cretaceous period, which began 101 백만년 전.
These size differences could indeed explain the existence of such sauropod diversity in the Neuquén Basin during the Late Cretaceous in terms of niche partitioning,” they wrote.
Researchers said that, while they don’t believe the creature to belong to a new species, they have so far been unable to assign it to a known genus of dinosaur.
The research was conducted by Argentina’s The Zapala Museum, Museo de La Plata, Museo Egidio Feruglio and the universities of Río Negro and Zaragoza.
