These are the first dromaeosaur tracks found in North America. The short trackway was made by a dromaeosaurid theropod, probably a large Deinonychus. Only two toes are preserved in each track because the inner toe on each foot, digit II, bore a huge sickle claw and was held up off the ground as the animal walked. The tracks are 8.7 inches long and indicate an animal just under 4 feet tall at the hip. The track is named Dromaeosauripus and dates to the Early Cretaceous, about 112 million years ago, in the Cedar Mountain Formation.
