Museum of Geology

The Museum of Geology is an exhibit facility that presents an astonishing array of fossils, minerals, and rocks that are representative of the geologic diversity of South Dakota. The fossil collection includes dinosaurs such as Triceratops, Tyrannosaurus and Edmontosaurus, a duck-billed dinosaur. Two spectacular marine reptiles dominate the central exhibit hall, the ferocious marine lizard, Mosasaurus, and the graceful long-necked plesiosaur. Alzadasaurus, lived in the last seaway to cover the region. Several exhibits draw attention to the wonderful fossil record of South Dakota Badlands. This paleozoo has saber-toothed cats, turtles, rhinoceroses, three-toed horses, giant pigs, oreodonts including one with unborn twins, camels, bird eggs, alligators, and brontotheres. These exhibits are complemented by an array of fossils from around the world and include plants, invertebrates and, vertebrates.The mineral collection includes a room of South Dakota minerals  that exhibits the State Gem, Fairburn Agate, and the State Mineral, Rose Quartz. Minerals from mines in the granitic rocks of the Custer and Keystone area dominate this room. The main section of the mineral exhibit is a systematic presentation of mineral diversity and includes more than 1000 specimens from around the world. A special exhibit of minerals that fluoresce under ultraviolet light is of great interest to our visitors. The Museum collections do not end with the specimans on exhibit. Each year the Museum of Geology acquires thousands of specimens for research, study, and teaching purposes. As a result the Museum is extremely active preserving  scientific specimens from our rich geologic heritage.
