1. Large Theropod Tracks Marker

Inscription. The large, well-preserved tracks in front of you are the beginning of a 17-step track-way of a very large, carnivorous dinosaur. Tracks of a similar dinosaur have also been found in central Texas. The tracks here are about 16-20 inches long and are from a dinosaur that was at least 8 feet tall at the hip. The intriguing thing about these tracks is that they indicate the presence of a very large dinosaur for which we currently have no skeletal evidence. A very large meat-eater remains to be found out there.

Name of Track: Irenesauripus
Early Cretaceous (~112 million years ago)
Cedar Mountain Formation

Erected by National System of Public Lands, U.S. Department of the Interior, Bureau of Land Management.
