Experts have uncovered the remains of a gigantic dinosaur in Argentina, and believe it could be one of the largest creatures to have ever walked the Earth.

Paleontologists discovered the fossilized remains of a 98 million-year-old titanosaur in Neuquén Province in Argentina's northwest Patagonia, in thick, sedimentary deposits known as the Candeleros Formation.
The 24 vertebrae of the tail and elements of the pelvic and pectoral girdle discovered are thought to belong to a titanosaur, a diverse group of sauropod dinosaurs, characterized by their large size, a long neck and tail, and four-legged stance.
In research published in the journal Cretaceous Research, experts say they believe the creature to be "one of the largest sauropods ever found" and could exceed the size of a Patagotitan, a species which lived 100 million to 95 million years ago and measured up to a staggering 37.2 meters (122 feet) long.
Without analyzing the dinosaur's humerus or femur, experts say it is not yet possible to say how much the creature weighs. However, the partially recovered dinosaur "can be considered one of the largest titanosaurs," experts said, with a probable body mass exceeding or comparable to that of a Patagotitan or Argentinosaurus.
The newly discovered dinosaur is thought to have a body mass exceeding or comparable to an Argentinosaurus, which measured up to 40 meters and weighed up to 110 tons.
