Blaine County Museum

501 Indiana St.
Chinook, MT 59523


The museum’s Paleontology Department has numerous exhibits with findings from the Judith River Formation. These exhibits feature hadrosaur, Gorgosaurus, and ankylosaur fossils discovered in the area. In addition, the museum displays gigantic marine reptiles, mosasaur and plesiosaur, as well as invertebrates that lived in the ancient ocean that covered this landscape 75-500 million years ago. The Museum also offers visitors the opportunity to handle fossils of sea creatures, plants, and dinosaurs that roamed Blaine County millions of years ago.

Did You Know?

When paleontologists make a find in the field, it is important that they have a way to transport the fossils back to the lab safely. In order to do this, they use a plaster mixture to encase the fossils. These casings are known as ‘field jackets.’ The specimen are then transported back to a lab where they will undergo the process of preparation. Depending on a paleontologist’s end goal for a specimen, the process of preparation will differ.
