The largest known dinosaur skeleton will go on display in New York at the American Museum of Natural History on Friday.
While the dinosaur species has not been officially named yet, paleontologists are calling the skeleton the Titanosaur because of its 37-metre length, said curator Mark Norell.
The species lived 100 million years ago in what is today known as Patagonia, a region in southern Argentina, and weighed around 70 tons - the equivalent of 10 African elephants. If stretched out, its neck would be long enough to allow the animal to peek through a fifth-floor window.
A farmer discovered the fossil in a Patagonia rock quarry. The skeleton is so long that it can't fully fit into the museum's dinosaur hall. Its head extends a few metres out of the door to the hall.
