This is one of the oldest museums which was founded in 1924 as the National Central Museum. In 1956 it was renamed the State Central Museum and in 1997 it became the Museum of Natural History. 

Today there are departments of Geography, Geology, Flora and Fauna, and Paleontology in the museum. Displays of stuffed and embalmed animals including the rare Gobi bear and wild camel, birds, and fish will give you a good idea about the rich fauna of Mongolia.

Most impressive is the Paleontology section. There are petrified eggs and bones of many dinosaurs that lived in the Gobi desert 60-70 million years ago and two complete skeletons of the flesh-eating giant Tarbosaurus and the duck-billed Saurolophus.

Petrified bones of 5 kinds of dinosaurs out of 7 that are known today have been discovered in Mongolia. The museum also has samples of various minerals that are found in the country.
