dreadnoughtus discovered in Argentina

Scientists in Argentina have discovered the remains of a huge dinosaur that would measure measure 26 meters long and that it was still in the growth phase. Researchers -led by paleontologist at Drexel University in Philadelphia Kenneth J. Lacovarahave nicknamed the specimen as Dreadnoughtus word that comes etymologically from the English phrase dread nothing: not afraid of anything. The dinosaur, whose remains were found in Patagonia, it would measure nearly 10 tall and weigh 60 tons when it died.

According to the findings published Thursday in the journal Scientific Reports, the Dreadnoughtus lived between 66 and 84 million years ago. He belonged to the group of sauropod dinosaurs known as titanosaurs. Most of these gigantic animals, says the report, so far known from a few remains. Last May, without going any further, the results of another study based on some remains also found in Patagonia, including a huge 2.40 meters femur was counted, belonging to that occurred in southern Argentina considered the largest dinosaur yet found in the world. The Dreadnoughtus belongs to the same herbivore species.

Researchers continue to study the fossils, which were in exceptionally good conditions of conservation at the time they found, in 2005 Four years later, in 2009, they managed to dig more than 200 bones of huge skeleton components, the most comprehensive ever found an exponent of its features, says Lacovara in the report. ” We have 16 tons of bones in my lab right now,” said the scientist in The New York Times.

The American newspaper uses an example to better explain the figures from the sheer size of these reptiles and clarifies that a Boeing 737 weighs about 43 tons empty, almost 20 less than the Dreadnoughtus. Researchers have already been able to reconstruct 45% of the skeleton, with a femur of more than 1.80 meters long. They are scanned by laser beams each of the bones and have been reproduced in three-dimensional figures. As a result, other paleontologists have the opportunity to study in spite of not having direct access to them and even make three-dimensional replicas.
