Fossils: Explore the story of vertebrate evolution in the Museum's famed fourth-floor fossil halls. In the Halls of Saurischian Dinosaurs and Ornithischian Dinosaurs, specimens are displayed according to their evolutionary relationships-which are determined by their shared physical characteristics-rather than chronologically. This organization allows students to trace the evolution and history of dinosaurs.

Evolution: Discover the birth of life on Earth in the Hall of the Universe. As students walk down the Cosmic Pathway, have them locate the span of time during which dinosaurs lived and compare that to the span of human history. The Hall of Biodiversity addresses the variety and interdependence of all living things.
