Hall of Giants

Giant Jurassic sauropods, Early Cretaceous bird-like predators and reptilian sea monsters from the mid-Cretaceous populate this newest addition to the Siebel Dinosaur Complex. Learn about the latest research in dinosaur growth and behavior and see some of the rarest fossil samples in the world. This hall includes many species of dinosaurs that can only be seen at the Museum of the Rockies.

Mesozoic Media Center

In the Mesozoic Media Center, visitors are electronically and technologically immersed in the world of dinosaur paleontology. Large plasma screens deliver video and broadcast content, and smaller interactive stations provide access to paleontological activities and information. This very high-tech hall brings the research of Jack Horner and the MOR Paleontology Department to the visitors’ fingertips.

Hallway of Growth and Behavior

Showcasing some of the only dinosaur embryos and nests in existence, a well-documented Maiasaura growth series, and other specimens from the Late Cretaceous, this hallway contains fossil evidence that has given scientists insight into how dinosaurs grew and lived.

Hall of Horns and Teeth

Dinosaur sculptures, sound effects, and hundreds of fossils bring the Late Cretaceous to life in the Hall of Horns and Teeth. Featuring the largest Tyrannosaurus rex skull in the world, the world’s most complete Triceratops growth series, and a massive Edmontosaurus tail with fossilized skin impressions, this hall treats visitors to a look at Montana during the last great age of non-avian dinosaurs.
