It has not yet been formally named by paleontologists who discovered it in Argentina in 2014. It belongs to a group known as titanosaurs.
The giant skeleton cast took a firm in Canada more than six months to make, based on 84 fossil bones that were excavated from the site in 2014.
The dinosaur is a new species and one of the largest dinosaurs ever discovered. It has not yet been formally named by palaeontologists who discovered it in Argentina in 2014.
The dinosaur belongs to the titanosaur family and was discovered by Paleontologists in the Patagonian Desert of Argentina in 2014 and lived about 100 to 95 million years ago.
The dinosaur is a new species and one of the largest dinosaurs-ever discovered and belongs to a group known as 'titanosaurs'.
The replica of the titanosaur weighs about 70 tonnes, is 17 feet-tall and stretches to nearly 122 feet-long.
A fossil of the titanosaur stands next to a replica of the dinosaur, one of the largest-ever discovered, as it is unveiled at the American Museum of Natural History, in New York City.
Paleontologist Diego Pol, who helped lead the excavations, said that the discovery was a 'once in a lifetime' moment.

The skeleton cast of a titanosaur is seen during a media preview at the American Museum of Natural History in New York. The new, 122-foot (37-meter) dinosaur skeleton, unveiled on Friday, is too long to fit in the fossil hall and so its neck and head will poke out toward the elevator banks, offering a surprise greeting when the lift doors open.
