The Museum's paleobotany collection contains several hundred fossil plant specimens primarily from Jurassic to late Pleistocene. The most important specimens are ~120 million-year-old fossil cycads from the Dakota Sandstone near Edgemont, South Dakota, one of the largest collections from the former Fossil Cycad National Monument. Other fossils include leaves, seeds, and petrified wood. Paleobotany also houses a modern herbarium with 200 plant folders, representing Black Hills and Badlands flora.
