The Glendive Dinosaur and Fossil Museum in Glendive, Montana, is a private institution founded by Otis Kline and owned by Advancing Creation Truth. Built between 2005 and 2009 largely by volunteers, it presents dinosaurs and fossils through a Young Earth creationist interpretation of Genesis, including claims that humans and non-avian dinosaurs lived together and that dinosaurs were on Noah’s Ark. The museum calls itself Montana’s second-largest dinosaur museum and the state’s only creationist one. Since opening in 2009, it has drawn controversy in a region known for major fossil discoveries, with paleontologists criticizing its rejection of mainstream geology and evolutionary science.
