Dinosaur paleontologist Scott Sampson, is shown making remarks as he stands next to a reconstruction of a &quot;Nasutoceratops titusi&quot; during a news conference at the Natural History Museum of Utah Wednesday, July 17, 2013, in Salt lake City.   The dinosaur was a wide-bodied plant-eater that grew to 15 feet long and weighed 2 1/2 tons. It's unique for its oversized nose and exceptionally long, forward-pointing curved horns over the eyes. It's part of the same family as the well-known Triceratops. Photo: AP
