Expertologists have found fossils from dinosaur species that know almost unidentified in the Patagonia region in Argentina, authorities have identified.
The "new" dinosaur – known as "Bajadasaurus pronuspinax", describes the shape of the Bajada Colorada geology in the Neuquen section where the remains of the animal that lived for around 140 million years ago were found – which belongs to the sauropod group.
It is helpful for the large upper spikes that cover its; neck and back, according to scientists announcing their discovery at the Center for Cultural Science
Paleontologist Pablo Gallina, one of the four authors from the study, told EFE that Bajadasaurus is a member of the dicraeosaurid family within the larger sauropod group.
"The sauropods are big dinosaurs with long nests and long tails, but especially this is a small family in the sauropod that was about nine meters long," said Gallina.
The researcher, who also works with the Scientific and Technical Research Council (Conicet), said the name "gnuspinax" at Bajadasaurus is due to & # 39; And it's a real feature (feature) of the new dinosaurs … which is a long spell that runs across its pork. "
During the course of the study, scientists discussed a number of ideas about the work of spirits, because – said Gallina – from fossils it is "very difficult" to be able to say if the spiders were associated with wild wheat to store fat resources or a bit of "sail" to help control the temperature of the body.
However, they made the final decision that the "most likely" idea was that the spiders were the protection structures for those dinosaurs to eat soils.
"It would not be an active defense, but always protected protection – that is, a type of warning attack. These are structures that warn carnivores and They could come up. Squirrels come up, seeing a large structure twice (about an attack), "said Gallina.
Their first fossils of this dinosaur were found in the end of 2013 and since then researchers have been able to; going on with the job that takes time to be carefully cleaned and done; Visit a variety of museums to compare with the remains of other species from around the world.
The findings of the investigation by four paleontologists and researchers from Conicet, Foundation Felix de Azara, the University of Maimonides and the Paleontological Museum Ernesto Bachmann were published on Monday in the Scientific Reports magazine.
