Fossil Halls at the American Museum of Natural History

This hall focuses on the rise of modern mammals after the extinction of the dinosaurs. It explores how mammals adapted, diversified, and spread across continents over time. Skeletons of advanced extinct mammals like ancient horses, dolphins, and whales show evolutionary changes that shaped today's mammals.

• Featured exhibits: Woolly mammoth, horses, elk

This hall showcases plant-eating dinosaurs known for their beaks and bony armor. You’ll find fossils of famous species like the Stegosaurus and Triceratops, alongside less-known but equally fascinating armored and duck-billed dinosaurs.

• Featured exhibits: Triceratops skulls, Stegosaurus, Corythosaurus

Explore the origins of mammals, tracing their development from small, shrew-like creatures to more complex forms. This hall highlights early evolutionary traits and transitional forms that bridge the gap between reptiles and mammals.

• Featured exhibits: Saber-toothed cat, early primates

This hall explores how animals with backbones first evolved. From jawless fish to the first amphibians, it covers the earliest stages of vertebrate life. The displays highlight adaptations that allowed life to move from water to land.

• Featured exhibits: Early fish fossils and the first amphibians, transitional forms

This is the starting point for exploring the fossil halls. It features a giant interactive evolutionary tree that connects all major fossil groups in the museum. The Titanosaur, one of the largest dinosaur reconstructions ever, also stands here.

• Featured exhibits: Titanosaur, fossil timeline, digital displays
