The American Museum of Natural History in New York City has some large exhibits. There’s the 94-foot, 21,000-pound fiberglass model of a blue whale that curves gracefully over the Hall of Ocean Life. There’s the 63-foot long “Great Canoe” carved around 1878 by Native people from the Northwest Coast. But those exhibits will be dwarfed by what is to come: a 122-foot long skeletal cast of a newly discovered species of Titanosaurus, reports Margaret Rhodes for Wired.
