Constructed by the city of Rapid City and the Works Progress Administration, WPA Project #960's dinosaurs were designed by Emmet Sullivan. 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 names; he grouped "Apatosaurus" within Opisthocoelia. Sauropoda is still used as the group name. In 2011, John Whitlock published a study that placed "Apatosaurus" a more basal diplodocid, sometimes less basal than "Supersaurus".

It was theorized that they lived partly submerged in water, perhaps in swamps. More recent findings do not support this; sauropods are now thought to have been fully terrestrial animals. A study
