This Museum dramatically showcases New Mexico's rich legacy of prehistoric life. Beginning with the formation of the universe and ending with the present day, the Museum offers snapshots of what New Mexico was like millions of years ago, when dinosaurs roamed the Earth. Today, these fascinating animals abound at the Museum, starting with the life-sized sculptures of a Pentaceratops (a dinosaur found only in New Mexico) and an Albertosaurus welcoming guests outside the building. The Museum welcomes more than 250,000 visitors each year, and its learning-and-fun approach to informal science education, coupled with its location in Albuquerque's tourist-friendly Old Town, make it the most-visited museum in the state. Permanent exhibits include an active walk-through volcano, realistic Ice Age cave, living forest and marine aquarium, Startup: Albuquerque and the Personal Computer Revolution, and Extreme Screen DynaTheater. The Museum also houses a state-of-the-art Planetarium, Observatory, and astronomy exhibition hall.
