The American Museum of Natural History has the world's largest collection of dinosaur fossils, so you don't want to miss a chance to see them in person. The Saurischian dinosaur hall features the Tyrannosaurus Rex and Apatosaurus (formerly Brontosaurus), as well as many other fossils from the Saurischian branch of dinosaurs.
Just a short walk from the Tyrannosaurus Rex and Apatosaurus, is the museum's second major hall of dinosaur fossils, all of whom have a backward facing pubis bone. The two stars of this hall are the Stegosaurus and Triceratops.

Artifacts from Native American peoples in the East and in the Plains are engagingly displayed throughout this exhibit. Models of dwellings used by Eastern Woodlands people, including longhouses and wigwams are particularly interesting to examine. This area is also home to one of the museum's most important pieces -- Folsom Point -- an arrowhead found in 1926 near Folsom, New Mexico, that proves that there were humans in the Americas as early as the last ice age.
