The fossil halls
The museum’s fossil collections on public view fill the entire fourth floor, reached through the Wallach Orientation Center, with halls of dinosaurs and of mammals and their extinct relatives.
Ocean life and the Northwest Coast
The Milstein Hall of Ocean Life is centred on a 94-foot model of a blue whale. The Northwest Coast Hall, established in 1899 by the anthropologist Franz Boas, is the museum’s oldest hall.
Earth and space
On the north side, the Rose Center for Earth and Space houses the Hayden Planetarium inside its great sphere, beneath a six-storey glass cube.
