New dinosaur species discovered in American southwest

Scientists have added another dinosaur species to the prehistoric catalog, and this one was found in present-day Utah.
Researchers working in Grand Staircase-Escalante National Monument discovered the new species of dinosaur— a large, horned, herbivorous creature that could have been anywhere from 19 to 26 feet long and weighed in at one to two tons. It took them three field seasons to excavate the fossils.
