"At 122-feet-long, as you can see, he doesn't even fit in the gallery," said the museum's president Ellen Futter.

The dinosaur dwarfs the museum's famed Blue whale display. The massive cast is based on fossil bones excavated in the Argentine Patagonia in 2014. Titanosaur is the creature's tentative name, with its official title yet to be determined, CBS2's Vanessa Murdock reported.

Diego Pol, a paleontologist from the Museo Egidio Fergulio in Argentina, was the one who initially unearthed the fossils, after a rancher claimed he found dinosaur bones on his property in Patagonia back in 2012.

"The quarry had over 200 bones, of six, not one --but six -- different giant dinosaurs," Pol said.

One of the original fossils of the creature's thigh bone is bigger than a typical human being -- aroud the size of a living room couch. Scientists used the femur bone to estimate the dinosaur's weight to be around 70 tons.

"One thing we do know about dinosaurs is that they grow extremely fast," Michael Novacek, a museum paleontologist, said.

Futter welcomed children from nearby P.S. 87 to be the first to see the giant. Ky Shan, 9, was impressed.

"Ohhhh that's big and then when I saw the whole thing, I was like woah," Shan said.

"And you saw its head popping out of the door?" Diamond asked.

"But the head is small compared to its titanic body," said Shan.

The permanent exhibit opens to the public on Friday.
