Bozeman's Museum of the Rockies (September 8, 2025)

Montana is rich with dinosaur fossils, with more than 75 species discovered there, more than any other U.S. state. Significant finds include the world's first T. rex and the first baby dinosaur bones discovered in North America. 

The museum houses the largest collection of dinosaur fossils in the world, including this reconstructed T. Rex skeleton. In another part of the museum, you can watch paleontologists cleaning and preserving dinosaur fossils.
