Scientists Unearthed Massive Fossils that May Belong to New Largest Dinosaur

A group of scientists has unearthed a gigantic, 98-million-year-old fossil, in Argentina and they believe that the bones may have belonged to the new largest dinosaur ever identified.

The publication of the National University of La Matanza, the CTYS scientific agency or the Agencia CTYS, on Thursday, January 21, 2021, has revealed that the observed bones appear to be from a gigantic sauropod which maybe ten (10) percent larger than those of Patagotitan mayorum, the largest dinosaur known to date.

Only twenty-four tail vertebrae and bits of pelvic bone have been found so far.

“Although we still cannot make estimates of body mass due to the absence of long elements such as the humerus and femur, based on the observation against other bones that we do have, we calculate that it would have reached a size similar or greater than Patagotitan,” Dr. Alejandro Otero, CONICET researcher at the Vertebrate Paleontology Division of the Museo de La Plata, explained.

According to Dr. Jose Luis Carballido, researcher at the Egidio Feruglio Museum and CONICET (Consejo Nacional de Investigaciones Científicas y Técnicas), the fossils were discovered in 2012 but the excavation was only carried out in 2015. The research about this, however, has just been recently published.

The research on this massive fossil was published scientific journal Cretaceous Research on January 12, 2021. It is called the “Report of a giant titanosaur sauropod from the Upper Cretaceous of Neuquén Province, Argentina” with Dr. Alejandro Otero as the lead author.

The experts’ quest in finding more parts is not yet over. “The part of the skeleton that was found is quite articulated, which makes us think that there should be more bones that will surely begin to be seen as soon as we can continue with the excavations,” Otero revealed.
