Grallator Dinosaur Track

Caption: This 4-inch long Grallator dinosaur track is among four types of dinosaur footprints identified by University of Utah geologists at a large dinosaur "trample surface" in the Paria Canyon-Vermillion Cliffs Wilderness near the Arizona-Utah border. They were left by a small dinosaur -- perhaps only 3 feet tall -- some 190 million years ago.
