Museum of the Rockies will open a new, permanent Tyrannosaurus rex exhibit in its Siebel Dinosaur Complex on Saturday, April 11, 2015. Called The Tyrant Kings, the exhibit will display a 12 feet tall and approximately 40 feet long real fossilized skeleton named Montana's T. rex. The Tyrant Kings will also include a series of six skulls from MOR's collections that presents the growth of T. rex - from a small, juvenile specimen to the largest T. rex skull ever discovered.
With the opening of The Tyrant Kings, MOR joins an elite group of museums around the world to display real, fossilized T. rex skeletons. The overwhelming majority of museums display replicas or casts, not actual fossil skeletons.
Discovered in 1997 near Fort Peck, Mont., and owned by the U.S. Army Corps of Engineers, Montana's T. rex was originally named "Peck's Rex." Museum of the Rockies renamed the dinosaur in honor of the state of Montana and one of its great resources.
