The 13,400-square-foot (1,240 m2) museum includes dinosaur skeletons, skulls, and reconstructions, with dozens of displays featuring other fine fossils and minerals.

Notable exhibits include international award-winning feathered dinosaur models,[1][2] a complete Triceratops prorsus skull; the holotype skull of the tyrannosaur Daspletosaurus wilsoni; a complete skull of the only Lambeosaurus collected from the USA; an articulated hadrosaur arm with mummified skin; and full standing mounts of Allosaurus and Albertosaurus.

The original exhibit included skeletons and models made by companies and artists from Utah, Texas, and North Dakota.

In 2015, ownership of the museum's fossil collection and related exhibits was transferred to the City of Dickinson.

Since 2016 Badlands Dinosaur Museum has been collecting dinosaur fossils from the Judith River Formation of Montana, with many of the latest discoveries on display in the museum, or visible in the public viewing preparation lab.
