A 17-step trackway begins with these large, well-preserved tracks left by a very large carnivorous dinosaur. Similar tracks have also been found in central Texas. The tracks here are about 16-20 inches long and were made by a dinosaur that was at least 8 feet tall at the hip. These tracks indicate the presence of a very large dinosaur for which there is currently no skeletal evidence. This track is named Irenesauripus and dates to the Early Cretaceous, about 112 million years ago, in the Cedar Mountain Formation.
