They discover rest of dinosaurs with giant thorns

A new species of herbivorous dinosaur was discovered in Patagonia Argentina. The remains found account for the existence, 140 million years ago, of a species of dinosaurs with thorns that inhabited the lands of the south of this country. The name assigned to this variety is Bajadasaurus pronuspinax .

Those responsible for the finding were scientists from the Fundación Azara-Universidad de Maimónides and the CONICET (National Council of Scientific and Technical Research of Argentina). It would be large reptiles with long barbs that they used to avoid attack by predators.

General characteristics of dinosaurs with thorns

Details and characteristics of the Bajadasaurus were published in the Scientific Reports; Bone remains are included in the group of sauropods. The new specimen would thus be a relative of the aragosaurs and braquisaurs, two of the greatest ancient inhabitants of the planet.

Specifically, the discovery of the dinosaurs with thorns took place in a geological formation of the province of Neuquén, called 'Bajada Colorada'. As with every archaeological finding , scientific questions are reformulated to give rise to new questions.

In this case, the possession of the thorns is compared to the property of camouflage the chameleons and, in general, those animals that have evolved towards their own defense mechanisms . The pronuspinax , on the other hand, would have developed a complete system of long and sharp thorns scattered on the back and neck.

The dimensions of this new species discovered reached nine meters long. The thorns were no more than a continuity of the animal's own vertebrae. In addition to serving as camouflage, this resource offered a powerful defense mechanism, thanks to resistant covers that covered the protuberances.

How was the discovery of the dinosaurs with thorns?

Bajada Colorada's research team was carrying out expeditions in the area since 2010. of bones that gave the pattern of the existence of fossil remains. Since then, the hope of finding a new species of dinosaur mobilized scientists.

140 million years ago that sector of Patagonia was covered by meadows in a relatively dry climate. The temperature then was warm, similar to the African savannas.

The difference between species was the vegetation; the plants consisted of coniferous shrubs, ferns, equisetos and varieties of what were the first flowers. There was a river that, curiously, was sailing in the opposite direction to the current one, that is, towards the Pacific.

It is believed that, thanks to the aquatic current and a unique situation of 'river elbow 'In this area, the remains of several animals came to the region. Approximately 250 dinosaur species have been found in Argentina.

Most of these ancient dinosaurs lived in the province of Neuquén.However, from the shape of the eyes, very close to the skull, they had the ability to control what was happening around them.

The director of the research by CONICET, Pablo Gallina, ensures that dinosaurs with thorns are especially significant for science archaeological . The etymology of the name means Descent by the place of the finding; saurus , because they are lizards; pronus , in reference to its forward inclination; and spinax , for its spines.

Until now, it was known of several 'deterrent mechanisms' to predators by herbivorous long-necked dinosaurs. For some it was a salvage the tail of whip, the mallets or a skin type armor. The Bajadasaurus pronuspinax , with its neck up to 2.5 meters, used its spines as camouflage and as a defense.

Following all the data have compiled, we reached truly surprising conclusions. In this sense, the 'sheath' of creatine draws the attention of scientists by the resistance similar to the horns of certain mammals.

In short, dinosaurs with thorns allow to leave open the doors of scientific speculation and knowledge. Of gigantic dimensions, this species can be framed of the largest herbivores on the planet .
