The duckbilled hadrosaur hasn't entirely gotten its due, according to recent research. Paleontologists working on the fossilized remains of one of these dinosaurs say they were larger and faster than previously believed.
Hadrosaurs probably weighed about 3.5 tons, and were up to 40 feet long. They were quick, muscular, and probably capable of outrunning a T. Rex. The work isn't complete yet, but the paleontologists involved say the fossil they're working with is an incredible specimen. They're even learning about its skin. More details will emerge this Sunday night, when the National Geographic channel airs "Dino Autopsy," a program about the specimen.—Gregory Mone
