Hadrosaurs were better runners than earlier thought. The fossilized hadrosaur is well preserved that scientists discovered that its muscle mass is larger and learned that it was even more muscular than what was thought before. Its hindquarters are 25 percent larger than previously thought, meaning they can run up to 28 mph or faster, probably to outrun predators like the T-rex who has a 10 mph running speed. 

They discovered it to be 3 and a half tons in weight and about 40 feet or 12 meters long. The fossil was found in 1999 in North Dakota by a teenager name Lyson, and is now being studied in the world's largest CT scanner operated by Boeing Co. The fossilized dinosaur's name is Dakota.
