One of the premier attractions in New York City is the Museum's series of fossil halls, including its two famed dinosaur halls in the David H. Koch Dinosaur Wing, as well as the Lila Acheson Wallace Wing of Mammals and Their Extinct Relatives.
The Museum is home to the world's largest collection of vertebrate fossils, totaling nearly one million specimens. More than 600 of these specimens, nearly 85 percent of which are real fossils as opposed to casts, are on view.
Only the animals displayed in the Hall of Saurischian Dinosaurs and the Hall of Ornithischian Dinosaurs are actually dinosaurs. Other fossil halls are the Hall of Primitive Mammals, the Paul and Irma Milstein Hall of Advanced Mammals, and the Hall of Vertebrate Origins.
