Dinosaur bones found on the territory of the United States 39, current Argentina
They are the largest animals that went to Earth with a mass equal to the spaceships.
However, we still do not know how these dinosaurs reached such massive proportions.
A new discovery of dinosaur bones in Argentina has provided new evidence. the giant growth process.
According to paleontologists, the animal "applied" a new strategy to achieve a significant size. In particular, it has been characterized by fast and effective flashes, similar to birds, to the lungs.
Dinosaur fossils were found in northwestern Argentina during a field study. They discovered four skeletons – a new species and three related dinosaurs

Here's how bones of dinosaurs are drilled from the breed
"We can see that there is a new species that we call Ingentia prima, in Latin it means" the first giant ", says Dr. Cecilia Appalteti of the 39, National University of San Juan.
This dinosaur dates from the Triassic, and thus appeared 47 million years earlier than the famous herbivorous diplododes and long-necked brahiosaurs.
It was not so big, weighed about 10 tons, but its discovery is unexpected, since it appeared so early on the path of evolution of the dinosaurs

reaches a length of 10 meters
A new type of dentist, Ingentia prima and similar species, is classified as sickle cell.
39, is a dinosaur whose scientists have found the bones? a representative of the group called zoologophagus, which means "legs like a lizard". Later, they turned into four-legged creatures that became the largest animals that once walked on the ground.
The dinosaur had a long neck and a long tail, although it did not reach the size of the pedigree.
It was about 10 meters long

How did it become so huge?
Like the dinosaurs who lived later, he had airbags, similar to the bird that was needed to cool large animals and provide them with a lot of oxygen.
The growth rings of his bones show that he grew up very quickly.

"We were able to observe in the bones [через кільця росту] that there were noticeable periods of growth," says Dr. Abaledetti, who was part of the team that found the skeletons.
A study of his group shows that there is more than one way The growth of dinosaurs to huge proportions
They suggest that there might even be larger dinosaurs and more amazing that have not been found yet

"It's a new way to get the body size at an early stage of the evolutionary history," Ms. Apaldetti said, "This path is not the same. has not been used in the history of dinosaurs. "
