Burke Hall: Life Among Dinosaurs

Fossils are windows into lost worlds. They reveal how, when, and where living things evolved as their environments changed.

Welcome to Life among Dinosaurs. In the wake of the extinction event, 252 million years ago, a new fauna emerged. Two large dinosaurs, Brontosaurus and Stegosaurus, occupy the middle of the room. Around the perimeter of the room, you can explore fossil deposits of different ages and locations – including fossils found locally.

Under The Age of Reptiles mural by Rudolph Zallinger, we explore the evolution of locomotion through examining fossils. Learn about tetrapods emerging from aquatic to terrestrial environments, the adoption of an upright posture that allowed breathing while running, and the origins of powered flight. You’ll learn that many aspects of locomotion evolved for different purposes and were later used in another way.

Deinonychus
117 to 101 million years ago

You might recognize this dinosaur by another name—the fictional velociraptors of Jurassic Park were inspired by this relative of their real-life counterparts.

Connecticut Fossils

As the rift valley lakes and floodplains of Connecticut were covered with mud, fish and dinosaur footprints fossilized.

Brontosaurus

Back and better than ever—with 27 new vertebrae and a tail raised in the air, this Brontosaurus is scientifically accurate.
