Was Argentine the largest dinosaur that existed? | Digital Trends Spanish
According to research published this week, the fossil remains of a dinosaur found in Argentina in 2012 could be larger than the Patagotitan mayorum, known until now as the largest dinosaur in the world.
The remains correspond to a 98 million-year-old sauropod and are 10 to 20 percent larger than those of the Patagotitan mayorum, which weighed about 70 tons, measured 40 meters in length and had a very long neck, according to Alejandro Otero, a researcher at the Vertebrate Paleontology Division of the La Plata museum.
“What has been found so far are the first 24 vertebrae of the tail, elements of the pelvic girdle, the pectoral girdle and the remains continue under the rock, so we will continue with their rescue in future campaigns,” said the scientist.
Although the dinosaur was found in 2012, excavations began in 2015. Researchers also believe there are still several years to go before it can be completely unearthed.
“The specimen is great because it is practically articulated and we have more than half of the tail, many hip bones and, obviously, it continues inside the rock, so we are going to have a few more years of excavations”, explained the paleontologist José Luis Carballido.
Thus, the uniqueness of this finding and the relevance it could have excite researchers.
“We suspect that the issue could be complete or almost complete. Everything will depend on how the excavations continue. But regardless of whether it is larger or not, the appearance of an articulated dinosaur of these dimensions is something very novel, “adds Alberto Garrido, director of the Museum of Natural Sciences of Zapala, in the province of Neuquén.
The discovery of this dinosaur was made thanks to the joint work of the Argentine universities of Comahue and Río Negro, the Egidio Feruglio Museum, as well as researchers from the Museo de La Plata and the University of Zaragoza, in Spain.
The results of this research have been published in the journal Cretaceous Research.
