Ecology & Environment


Dig up the past and explore the mysteries of earth.

Explore our planet’s history and the creatures that once roamed its surface. Dig up fossils, watch a Tyrannosaurus rex plan his next meal (an unlucky Triceratops), see a tornado forms right before your eyes, or feel the earth shake beneath your feet.


Rediscover our Dinosaurs

Science never stops. Since our Cretaceous diorama was installed in 1991, paleontologists have continued to learn more about T-Rex, Triceratops, Pteranodons and Cretaceous mammals. This new information gives us a different idea of what this diorama scene may have really looked like!

Visit our beloved T-Rex on the lower level to learn from our brand-new reader rails, which shed new light on these dinosaurs’ appearance and behavior.


Dana Brown Fossil Prep Lab and Dig Site

Explore, excavate and experience our realistic interactive dig site as you discover the world of paleontology. Pretend you’re a paleontologist as you chip away at the dirt to uncover dinosaur fossils buried deep beneath the earth in a reconstruction of the Badlands of Montana.

Stop by the prep lab to watch staff and volunteers work on preparing real dinosaur fossils. The fossils in the dig site are casts from real fossils that can be seen on display in the prep lab!

Note that all children must be accompanied by an adult. Please no food or drink in the dig site.
