Miniature models of a dinosaur that was found in Argentina are on display in Santiago.
Three years after the discovery of a dinosaur in Argentina, a group of paleontologists from the country presented their findings on a tail that has stumped researchers.
The remains of a dinosaur were discovered during excavations at a site known to harbor many fossils, but the team thought they were dealing with an existing species of dinosaur.
"That was the biggest surprise," said Alexander Vargas, one of the paleontologists. This structure is amazing.
The researcher said that the weapon produced by the tail was completely different from anything we know about dinosaurs.
The structure of the plaques in the skin were aligned on either side of the tail, making it look like a large fern.
Paleontologists estimate that the dinosaur lived in the area 71 to 74.9 million years ago. It was almost seven feet long and weighed over 150 kilograms.
The scientists who published their research in the journal Nature said that the animal could represent a previously unknown lineage of armored dinosaurs that were found in the northern part of the continent.
The remains of a new species of dinosaur are on display in Santiago.
We don't know why the tail evolved. The team knows that armored dinosaur groups have a tendency to develop their own defense mechanisms.
The Las Chinas valley stretches for 15 kilometers and is located south of Santiago. There are a lot of fossils in various rock outcrops.
The scientists were able to surmise that America and Antarctica were close to each other millions of years ago.
There is strong evidence that there is a biogeographic link with other parts of the planet, in this case Antarctica and Australia, because we have two armored dinosaurs there closely related to the Stegouros.
