Fossil Diorama and Displays
A feeling of "then and now" radiates from the life-size diorama showcasing mounted skeletons--they're replicas--of the surprising Miocene Epoch mammals discovered in historic Agate Springs quarries. Meet the scavanging Dinohyus ("Terrible Pig"), the long necked, claw toed Moropus ("Sloth Foot"), or snarling carnivore Beardogs. Where did paleontologists find the fossils we later used for these plaster casts? In the Fossil Hills, visible through three large windows beyond the diorama. Which you can hike after touring the museum!
James H. Cook Collection: A Window Onto Lakota LifeTwo rooms of the visitor center are dedicated to James Cook's family and their interactions with Chief Red Cloud of the Lakota Sioux.
This light and climate controlled exhibit displays amazing examples of craftsmanship and historical significance.
Check out Chief Red Cloud's chief shirt, the war club American Horse used to kill Captain William Fetterman, an elk hide painted with the Lakota and Cheyenne tribes' side of the Battle of Greasy Grass (aka "Custer's Last Stand"), and many other fascinating items.
If you're on a road trip through the Northern Plains and visiting other sites related to the Plains Indian Wars, like Fort Laramie and Fort Robinson, this exhibit is a must-see.
