dinosaur skull at museum of the rockies
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 Montana rocks from the Jurassic and Cretaceous periods. Dinosaur dig crews led by paleontologist and curator Jack Horner, science advisor to the Jurassic Park films and the 2011 Fox TV show Terra Nova, excavate fossils which are prepared and studied at the Museum in Bozeman. 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 Dr. Horner is constantly updating our exhibits based on new research and fossils that are being excavated and studied by his team.

MOR is also a federal repository for fossils, and our collections are considered part of the United States' national treasures.
