Los Angeles’ Natural History Museum is famous for its two-story Dinosaur Hall, a 14,000-square-foot permanent exhibition showcasing hundreds of fossils and impressive mounted dinosaur skeletons.
Even lifelong Angelenos may overlook this magnificent collection hidden in Exposition Park, but if you’re a resident of L.A. County, you’re entitled to enjoy free admission for two hours on weekdays.

Dinosaur Hall
The Jane G. Pisano Dinosaur Hall displays over 300 fossils and 20 mounted dinosaur skeletons from the Mesozoic Era (about 252–66 million years ago).
Highlights include the world’s only display of baby, juvenile, and adult Tyrannosaurus rex skeletons, demonstrating how the predator changed as it grew. Other favorites include the “Dueling Dinos” display, which presents a T. rex and Triceratops in a striking combat scene, and the 15-foot pregnant plesiosaur fossil. Visitors can observe the towering skeletons from every angle thanks to well-placed walkways and balconies.
The exhibition is designed with interactive elements in mind, including digital displays, touchable fossils and casts, and a peek into how paleontologists conduct their research.
