BHI has been collecting and preparing fossils for nearly 50 years. Our collection is one of the finest accumulations of both vertebrate and invertebrate fossils, along with minerals, from the Black Hills region. It includes: dinosaurs of the Hell Creek and Lance formations, including the largest compilation of Tyrannosaurus rex; a massive assortment of ammonites and cephalopods with an emphasis on Late Cretaceous ammonites of the Western interior of North America; other Late Cretaceous molluscs from North America; Green River insects, plants, fishes and other vertebrates; Oligocene mammals and reptiles from the White River group; marine mammals from Peru; Late Cretaceous reptiles; Cretaceous fishes from North America and the Middle East (Lebanon and Israel); trilobites and crinoids. Throughout our excavations we have discovered dozens of new species, several new genera, and even a new family of fossils.
