The Geological Museum, in the east wing of the S.H. Knight Geology Building, exhibits the story of ancient Wyoming. Highlight exhibits include: one of only six mounted fossil skeletons of the well-known dinosaur Apatosaurus (Brontosaurus); mounted skeletal cast of the world-renowned “Big Al” the Allosaurus; a 50-million-year-old garfish from Wyoming’s Green River Formation (one of the largest complete freshwater fossil fish on display in the world); casts of skulls of Wyoming’s state dinosaur, Triceratops; and its contemporary, Tyrannosaurus rex; mounted skeletons of Miocene rhinos and camels; and a fluorescent mineral room, featuring specimens from Wyoming and the world. The museum maintains important display collections (particularly vertebrate and invertebrate fossils) that are available for study by students, as well as scientists from other institutions. The museum provides unique opportunities for undergraduate students to pursue research and display projects in Wyoming paleontology.
