122-Foot Titanosaur: Staggeringly Big Dino Barely Fits into Museum

An incredibly long-necked dinosaur, with leg bones the size of couches, is so massive that is has invaded not one, but two rooms at the American Museum of Natural History (AMNH) in New York City. The enormous titanosaur — an herbivorous beast that weighed 70 tons (64 metric tons) when alive some 100 million years ago — is the newest permanent exhibit to join the museum.
