Dinosaur Park Dinosaur Park Dinosaur Park is a tourist attraction in Rapid City, South Dakota, United States. 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. 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
Barosaurus Barosaurus Barosaurus ( ) was a giant, long-tailed, long-necked, plant-eating dinosaur closely related to the more familiar "Diplodocus". Remains have been found in the Morrison Formation from the Upper Jurassic Period of Utah and South Dakota (and possibly Africa, as exemplified by the Kadsi Formation). It is present in stratigraphic zones 2-5. The composite term "Barosaurus" comes from the Greek words "barys" (βαρυς) meaning "heavy" and "sauros" (σαυρος) meaning "lizard"; thus "heavy lizard". "Barosaurus" was an enormous animal, with some adults measuring more than 26 meters (85 feet) in length and weighing more than 20 metric tons (22 short tons).
