Scientists discovered fossils of the oldest known giant dinosaur in the north-west of a four-legged, medium-tailed, long-tailed herbivore who was the precursor Animals
The researchers said that the dinosaur, called Ingentia prima which means "the first giant", had up to 10 meters long and weighed about 10 tons and lived about 210 million years ago during the Triassic period .

Ingentia was one of the first members of a group of dinosaurs called sauropods that more than tar it included the largest terrestrial creatures on Earth , including Argentinian giants of Patagonia named Argentinosaurus Dreadnoughtus and Patagotitan Ingentia prima the origin of gigantism, the first steps for that, more than 100 million years later sauropods up to 70 tons like those who lived in Patagonia, "said paleontologist Cecilia Apaldetti of the National University of San Juan in Argentina lead author of the study published on Monday in the journal Nature Ecology & Evolution .

bones sauropods Later, the legs of Ingentia were not shaped pillar. His neck was also shorter than the later sauropods, which had one of the longest necks compared to the length of the body of any animal.
Dinosaurs first appeared in the Triassic, about 230 million years ago. The first was of moderate size, far from the immense dinosaurs of subsequent Jurassic and Cretaceous periods .

Apaldetti considered that Ingentia is not only the largest dinosaur but the largest land animal of any type up to that time . sometimes larger than other herbivores who shared the warm savanna environment that they inhabited. The largest predators were not dinosaurs, but grandparents of crocodiles who lived on Earth . an estra evolutionary theology of survival, especially for herbivorous animals, because size is a form of defense against predators "he said.
Scientists have identified important traits related to gigantism in Ingentia He had a bird-like respiratory system, linked to the development of air pockets inside the body which gave him large reserves of oxygenated air and kept him at the Despite its large size
Although the late giant dinosaurs grew up in an accelerated but continuous manner, a review of their bones showed that Ingentia increased seasonally instead of continuously, but at a rate still larger
Ingentia, known by two partial skeletons, was discovered in the Argentine province of San Juan
