The World's Largest Dinosaurs (April 16, 2011-January 2, 2012), a new exhibition at the American Museum of Natural History, goes beyond traditional fossil shows to reveal how dinosaurs actually lived by taking visitors into the amazing anatomy of a uniquely super-sized group of dinosaurs: the long-necked and long-tailed sauropods, which ranged in size from 15 to 150 feet long.
