When the national central museum was located in present location in 1956, it has been enriching its exhibitions and expanded as a big natural department, which has various kinds of geographical, flora, fauna and paleontological exhibits.Natural history involves historical process of 4.7 milliard years of that is very long term from the origin of the world until the origin of plant, animal and human. Thus our museum shows the briefness of these events by exhibitions and contributes knowledge to peoples mind. It has exhibits featuring Mongolia's geography, flora and fauna, including the requisite section with stuffed and embalmed animals, birds and even fish. Geologists will like the geology section (especially the awesome meteorites). Likewise, the birders will want to check off what they've seen at the Ornithological Gallery, stuffed (literally) with over 200 species. More impressive are the two complete dinosaur skeletons, which were found in the Gobi - the giant flesh-eating Tarbosaurus, 15m tall and four to five tons in weight, and the little duck-billed planteating Saurolophus at 'only' 8m.
