A team of researchers found in Argentina the remains of a giant dinosaur species that lived on Earth more than 200 million years ago, a scientific source announced on Monday.
This species, named Ingenia prima, is nearly three times the size of the largest dinosaurs of the Tribadic period. It was discovered in 2015 on the Balde de Leyes palaeontological site in the province of San Juan, 1,100 kilometers west of Buenos Aires.
The Mesozoic era is subdivided into three major periods: the Tribadic (from -251 to -200 million years ago), the Jurbadic (from -200 to -145 million years ago) and the Cretaceous (from 145 to -65 million years.)
The discovery was published Monday in the journal Nature Ecology & Evolution and distributed in Argentina by the scientific authorities of the National University of La Matanza.
"As soon as 'We found it, we realized it was something different, we discovered a shape, the first to be giant in the middle of all the dinosaurs, that's the novelty,' says researcher Cecilia Apaldetti of the Institute and Museum of Natural Sciences of the University of San Juan (IMCN) and Conicet (National Council for Scientific and Technical Research).
Researchers found vertebrae in the neck and tail, bones of the front legs and part of the bones of the hind legs.
It s "Herbivorous, quadruped dinosaurs, which are easily distinguished by their long neck and long tail, from the group sauropods," she said.
So far, it was thought that gigantism in dinosaurs had occurred during the Jurbadic Period, about 180 million years ago.
According to researchers' estimates, the discovered specimen measured 6 to 7 meters, was young and weighed about 10 tons, the weight of 2 to 3 elephants.
