Gallery Highlights At the Academy of Natural Sciences, you can wander among towering dinosaur skeletons or discover an indoor tropical butterfly garden. Explore ecosystems from around the world through our historic dioramas or be transported to the great outdoors through our hands-on discovery center for children. Beyond the 40-foot T. rex and fluttering tropical butterflies, you will find many interactive exhibits based on paleontology, minerals, mollusks, the food chain, natural history, and more.
