Carnegie Museum of Natural History

Carnegie Museum of Natural History, located at 4400 Forbes Avenue in the Oakland neighborhood of Pittsburgh, Pennsylvania, USA, was founded by the Pittsburgh-based industrialist Andrew Carnegie in 1896. It maintains an international reputation for research and is ranked among the top five natural history museums in the United States. The museum consists of 115,000 square feet (10,700 m) organized into 20 galleries as well as research, library, and office space. It holds some 22 million specimens, of which about 10,000 are on view at any given time and about 1 million are cataloged in online databases. In 2008 it hosted 386,300 admissions and 63,000 school group visits. The museum first made history in 1899 when its scientists unearthed the fossils of Diplodocus carnegii. Today its dinosaur collection includes the world's largest collection of Jurassic dinosaurs and its Dinosaurs in Their Time exhibition offers the third largest collection of mounted, displayed dinosaurs in the United States (behind the Smithsonian's National Museum of Natural History and the American Museum of Natural History).
