The cast of an enormous titanosaur skeleton will go on display at the American Museum of Natural History in New York City on Friday (Jan. 15). The cast is so large that it takes up two rooms, and it's even longer than the museum's iconic model of the blue whale. [Read the Full Story on the New Titanosaur

Assembling the cast

The cast consists of 84 replicas of fossil bones excavated in Argentine Patagonia. (Credit: Copyright AMNH | D. Finnin)


Fabricating the display

Scary welcome

The dinosaur model is larger than the exhibition area, so it welcomes guests to the museum at the elevators, as they enter the hall. (Credit: Copyright AMNH | D. Finnin)


A big guy

Studying the front leg (the scapula, humerus, radius and ulna) of the titanosaur, experts believe this giant could have looked into the windows of a five-story building. (Credit: Copyright AMNH | D. Finnin)


A leggy dino

The femur fossil alone is 8 feet (2.4 m) long. Using that information from the size of the bone, scientists estimate the animal to have weighed around 70 tons, the equivalent of about 35 cars. (Credit: Copyright AMNH | D. Finnin)

Coming together
