New species of sauropod dinosaurs were discovered in Argentina

A group of Spanish and Argentine paleontologists have discovered the ruins of a dinosaur who lived in the center of the country 110 million years ago, the La Matanza National University revealed on Friday.

The remnants came from three separate dinosaurs from the herbivorous group of sauropods, the most well-known of which are Diplodocus and Brontosaurus. This new species has been called Lavocatisaurus agrioensis.

"We found most of the cranial bones: the muzzle, the jaws, many teeth, and the bones that define the eye sockets for example and in this way we were able to create an almost complete reconstruction," said Jose Luis Carballido, researcher at the Egidio Feruglio Museum and the National Scientific Research Council.

Also, parts of the neck, tail and back were found.

"It's not just this discovery of a new species in an area where one would not expect to find fossils, but the skull is almost complete," added Carballido.

The relics belonged to an adult about 12 meters (39 feet) long and two minors about six to seven meters long.

Palaeontologists say that dinosaurs moved to a group and died together.

"This discovery of an adult and two young people also means the first recording of group shifting among the dinosaurs rebbachisaurus," said lead study author Jose Ignacio Canudo of the University of Zaragoza.

The area where fossils were found is unusual for dinosaurs, as would be a desert with sporadic lakes at that time.

The Sauropods were the largest creatures ever on the planet. It is believed that the Supersaurus could reach up to 33-34 meters in length and Argentinosaurus may have weighed up to 120 tons.

It was herbivorous four times with long necks and tails, mass bodies and small heads.

But the discovery at Neuquen, published in the journal Acta Palaeontologica Polonica, remains a huge surprise.

"While one can imagine that this group of sauropods could adapt to move into weaker environments, with little vegetation, low humidity and little water, it is a place where you will not be looking for fossils," said Carballido.
