An enormous, 122-foot-long dinosaur cast of the titanosaur is now on display at the American Museum of Natural History in New York City, but it’s so large—roughly the length of three school buses—that it extends into a second room. It’s even got the museum’s famous model of the blue whale beat by nearly 30 feet.
The remains of the 70-ton herbivore were discovered in the Patagonian desert region of Argentina in 2012. Experts used 3-D scans of the bones to completely digitize the skeleton. The data was then used to carve new bones from slabs of foam, which were then molded and cast in fiberglass.
