Fossils of the oldest giant dinosaur have been discovered by scientists from northwestern Argentina. Among the two main features, we have a four-legged herbivorous animal, a medium-length neck and a long tail, considered one of the largest terrestrial animals ever to exist on Earth.
The oldest giant dinosaur that has long inhabited the planet more than 200 million years ago was discovered by Argentine researchers at the paleontological site located near the province of San Juan, Argentina.
The dinosaur was baptized by the researchers " Ingentia prima ", the first giant ", because it weighed about 10 tons and measured more than 10 meters. Fossils of the Giant Dinosaur
Paleontologist Cecilia Apaldetti, of the National University of San Juan, Argentina, the lead author of the study published Monday in the journal Nature Ecology & Evolution, said: "We see in Ingentia prima the origin of gigantism, the first steps that allowed more than 100 millions of years later, sauropods that can reach 70 tons could emerge, like those who lived in Patagonia. "
It is remarkable that Ingentia prima was one of the first members of the group of dinosaurs called sauropods. later included the largest terrestrial species of the Earth, in this case the Patagonian giants Argentinosaurus, Patagotitan and Dreadnoughtus.

Another interesting aspect is that unlike late sauropods, the dinosaur found did not have its legs similar to the pilasters. In addition, his neck was shorter than these, which in turn had longer necks compared to the length of the body.
"Ingentia was not only the largest dinosaur, but also the largest land animal of any kind in his time," added Cecilia.
