Discovery of the remains of the oldest known giant dinosaur in Argentina

Scientists have discovered the remains of the oldest known giant dinosaur in northwestern Argentina, a four-legged vegetarian dinosaur and a neck of medium length and long tail. Called the "First Giant", reaches 10 meters and weighs about 10 tons, he lived 210 million years ago during the Triassic period, according to Reuters.

Ignatia is a former member of a group of dinosaurs known as sorobod, which later included the largest wild creatures on Earth, including Argentinosaurus, dredenotes, and pagetotans living in the Patagonian region. "We see in Incentia Prima the origins of the stratosphere and the first steps towards the emergence of sorobod dinosaurs with weights up to 70 tons after that," said Cecilia Apeldetti of the US. National University of San Juan Argentina and author of the study published Monday in the journal Nature Ecological and Evolution. A hundred million years like those who lived in Patagonia. "

The legs of the Angenta were not vertical like the Sorobod dinosaurs appeared later, and his neck was shorter.Sorobod is one of the world's longest animals. [19659005] Scientists believe that dinosaurs appeared at the beginning of the Triassic about 230 million years ago.The early dinosaurs were small unlike the giant dinosaurs that lived in the later Jurassic and Cretaceous periods. Originally thought that giant dinosaurs appeared about 180 million years ago.

Abalditi said that Ignatia was not only the biggest dinosaur but the most Great fauna never at this time.This was at least twice the size of the other plant species that lived with it in the warm savannah.At that time, they were not the biggest predators of dinosaurs, but great wild creatures rush crocodiles.

Scientists have identified important features associated with dinosaur incentia. He had a respiratory system similar to that of a bird, associated with the presence of airbags inside the body, which gave him a reserve of fresh air and kept his body cool despite her size.

Scientists discovered the Ingentia dinosaur in the province of San Juan, Argentina, and knew it from incomplete skeletons.
