Incredible! Most Well-Preserved Armored Dinosaur Was a 'Spiky Tank'

Miners discovered the 18-foot-long (5.5 meters) beast — a nodosaur, a cousin of ankylosaurs, which also had body armor but didn't sport club tails — in 2011 during routine work at the Suncor Millennium Mine in Alberta. Soon after, the Suncor Energy company contacted the Royal Tyrrell Museum of Palaeontology in Alberta, where the specimen has remained for the past six years, painstakingly being chiseled out, one inch at a time. "It was a very slow reveal, but it was a very exciting one nonetheless," said Caleb Brown, a postdoctoral fellow at the museum, and a co-author of a study describing the new species, which he expects to be published in a peer-reviewed journal this summer.
