Jurassic World unveiled the Indominus rex to the imaginary world. This winter, the American Museum of Natural History unveils "the Titanosaur" (official name pending) to the real world. This newly discovered dinosaur takes first place for size, proving that the real world can be just as enthralling as its big-screen counterpart. Dinosaur enthusiasts of all ages can flock to the Upper West Side starting today to see this new exhibit. Remains of the Titanosaur were discovered in 2014 by paleontologists on a dig in Argentina's Patagonia region; it is believed to have lived approximately 100 million years ago in what is known as the Late Cretaceous period. At 122 feet long and 19 feet high, and weighing in at around 70 tons, this regal beast is an herbivore. It's also too long to fit completely into its allotted fourth-floor space, so its charming neck and face will poke around into the elevator banks, greeting guests.
