Go behind the scenes of the new exhibition T. rex: The Ultimate Predator, which opens March 11 at the American Museum of Natural History, with paleontologist Mark Norell and the model makers to find out how they create the stunningly detailed, life-sized models of the iconic dinosaur as a baby, juvenile, and menacing adult. Warning: you may never think of T. rex the same way again.
