CORRECTION Dinosaur Discovery Utah
CORRECTS TO NATURAL HISTORY MUSEUM OF UTAH, NOT NATIONAL HISTORY MUSEUM OF UTAH - This photo released by the Natural History Museum of Utah, shows the cliff in the Grand Staircase-Escalante National Monument beneath which the fossilized skeleton of a newly-discovered dinosaur, Lythronax argestes, was found in southern Utah. Scientists say the bone-crushing carnivore is the equivalent of the great uncle of the T. rex. (AP Photo/Natural History Museum of Utah, Mark Loewen)
