Discover new species of dinosaur in Argentina



A team of Spanish and Argentine paleontologists found the remains of three specimens of a new type of dinosaur, with the age of 110 million years in the Argentine province of Neuquén, which at that time was a desert area.

Lavocatisaurus agrioensis and its discovery, published in the specialized journal Acta Palaeontologica Polonica released yesterday in Argentina by the Science, Technology and Society Agency (CTyS) of

According to the Argentine media La Voz is a herbivorous rebaquisura of the group of sauropodes, the quadruped herbivores with long neck and tails, among which there were giant species weighing more than 70 tons and other dwarfs that did not exceed 1

0 meters when they filled adult life, and who lived from late triass to late chalk eros.

"We found most of the legs that correspond to the skull: the snout, the jaws, many teeth. Also those who define the eye circle, and in this way we could do a very complete reconstruction," explained José Luis Carballido, a researcher at Egidio Feruglio- the Museum and the National Scientific Research of Argentina.

They also found some parts that belong to the neck, tail and back.

"It's not just the discovery of a new type of dinosaur in a place where you do not expect to find fossils, but also the skull is almost complete." Carballido added

The remains correspond to an adult sample with a height of about 12 meters , in addition two young fishes, about six and seven meters. Paleontologists believe that the animals went into groups and died together.

EL HALLAZGO

"This also meant the first record of a group shift in the rebaquisáurid dinosaurs," says José Ignacio Canudo of the University of Zaragoza. and the main author of the study.

In this regard, the expert reminds us that South America and Africa had not been separated at that time, so rebaquisaurides were also discovered in Africa and Europe.

Neuquén, where the remains were found, is unusual because it was then a deserted area with sporadic lagoons.

"Despite the fact that this group of sauropods could be adapted to move in fairly dry environments, low vegetation, low moisture and a little water, it is an environment where you would not look for fossils," concluded Carballido .

THE LARGEST OF THE WORLD …
In 2012 there were the fossil legs of six samples of Patagotitan mayorum in the Patagonia region of Argentina, the most widely described so far, according to a study published by the British Royal Society. On average it measured about 37 meters long, and when the neck was raised, it exceeded 20 meters.
