MOR is home to one of the largest and most famous collections of dinosaur fossils in the world. Dinosaur fossils in our collection have all been found in rocks from the Jurassic and Cretaceous periods in Montana and surrounding regions. Some of the most famous dinosaurs in the world such as Tyrannosaurus rex, Triceratops, and Deinonychus (very similar to Velociraptor) can be seen on display.

Many of our dinosaur fossils are on display in the Museum, but most of our collection stays in our storage facilities. MOR has the largest collection of T.rex fossils in the world, and exhibits are constantly updating our exhibits based on new research and fossils that are being excavated.

MOR is also a repository for federal fossils. Dr. John Scannella is our Interim Curator of Paleontology.
