Dedicated on May 22, 1936, it contains seven dinosaur sculptures on a hill overlooking the city, created to capitalize on the tourists coming to the Black Hills to see Mount Rushmore.

Sullivan also designed the "Apatosaurus" (formerly thought of as a synonym of "Brontosaurus") at Wall Drug nearby in Wall, South Dakota, the Christ of the Ozarks statue in Eureka Springs, Arkansas, and the
Apatosaurus which good skull material was known at the time. The mount construction was overseen by Adam Hermann, who failed to find "Apatosaurus" skulls. Hermann was forced to sculpt a stand-in skull by hand. Osborn said in a publication that the skull was "largely conjectural and based on that of "Morosaurus"" (now "Camarasaurus"). In 1903 Elmer Riggs published a study that described a well-preserved skeleton of a diplodocid from the Grand River Valley near Fruita, Colorado, Field Museum of Natural History specimen P25112. Riggs thought that the deposits were similar in age to those of the Como Bluff in Wyoming from
