Paleontologists found the fossilized stays of a 98 million-year-old titanosaur in Neuquén Province in Argentina’s northwest Patagonia, in thick, sedimentary deposits referred to as the Candeleros Formation.
The 24 vertebrae of the tail and parts of the pelvic and pectoral girdle found are thought to belong to a titanosaur, a various group of sauropod dinosaurs, characterised by their massive dimension, a protracted neck and tail, and four-legged stance.
“It is a huge dinosaur, but we expect to find much more of the skeleton in future field trips, so we’ll have the possibility to address with confidence how really big it was,” Alejandro Otero, a paleontologist with Argentina’s Museo de La Plata, instructed CNN by way of e-mail.
Titanosaur fossils have been discovered on all continents besides Antarctica. But the greatest “multi-ton” sorts of the species — together with these titanosaurs exceeding 40 tons — have principally been found in Patagonia.
Without analyzing the dinosaur’s humerus or femur, consultants say it’s not but attainable to say how a lot the creature weighs. However, the partially recovered dinosaur “can be considered one of the largest titanosaurs,” consultants mentioned, with a possible physique mass exceeding or comparable to that of a Patagotitan or Argentinosaurus.
Patagotitans could have been the world’s largest terrestrial animal of all time, and weighed up to 77 tons, whereas Argentinosaurus had been equally gargantuan, and measured up to 40 meters (131 toes) and weighed up to 110 tons — weighing greater than 12 occasions greater than an African elephant (up to 9 tons).
Experts imagine that the specimen strongly suggests the co-existence of bigger titanosaurs along with medium-sized titanosaurs and small-sized rebbachisaurids at the starting of the Late Cretaceous interval, which started 101 million years in the past.
“These size differences could indeed explain the existence of such sauropod diversity in the Neuquén Basin during the Late Cretaceous in terms of niche partitioning,” they wrote.
Researchers mentioned that, whereas they do not imagine the creature to belong to a brand new species, they’ve to date been unable to assign it to a identified genus of dinosaur.
The analysis was performed by Argentina’s The Zapala Museum, Museo de La Plata, Museo Egidio Feruglio and the universities of Río Negro and Zaragoza.
