Discover the World of Dinosaurs

Lambert Dinosaur Hall. Ekalaka has been an epicenter of dinosaur discoveries for the last century and continues to be a source of scientific discovery to this day. The exhibits of the Lambert Room include a mounted skeleton of the duckbill dinosaur Anatotitan copei (one of a few nearly complete specimens of its kind) as well as a complete skull of Triceratops. The badlands around Ekalaka have also produced pachycephalosaurs, pterosaurs, tyrannosaurs, and ankylosaurs. Notably, both the first known as well as the most complete juvenile T. rex have been found here, fueling much of what we know about how these animals grew. Mounts and casts of all of these are on display, along with countless other real dinosaur bones. Carter County has more than just dinosaurs, however. Exhibits also display the bones of sea reptiles and the shells of ammonites from when the Pierre Sea covered the midwest of North America. The Fort Union Formation records life after the dinosaurs, a landscape becoming increasingly dominated by small mammals. The Arikaree Formation and Pleistocene channel fill record the later arrival and origination of large mammals, like brontotheres and mammoths.
