The Great Plains Dinosaur Museum (GPDM) is located in the rich land mass of Northern Montana where some the world’s most preeminent dinosaur fossils have been discovered.  A site and member of the Montana Dinosaur Trail, GPDM maintains permanent exhibits of dinosaurs and other prehistoric fossils to advance the visitors experience, allowing them to appreciate, enjoy and fully understand the rich prehistory  of this region.  The Museum also provides the rare opportunity for both youth and adults to explore, dig and excavate fossils with their staff and paleontologist partners in scheduled educational and dig programs.

The Great Plains Dinosaur Museum (GPDM) is governed and operated by volunteer board members of the Judith River Foundation, Inc.   The Foundation is an IRS exempt 510c3 non-profit corporation established in 2002.  The GPDM is not a municipal entity, is not affiliated with any higher education institutions, receives no general tax support, and is entirely self-funded through membership fees, admissions, dig and tour revenue and fundraising.

GPDM is guided by a mission to curate and prepare paleontological resources for use in educational programs, scientific research and interpretive displays in support of the advancement of knowledge and the benefit of all people.
