The Natural History Museum is Ulaanbaatar's stop for Mongolia's deep natural past, especially the dinosaur fossils of the Gobi. The headline exhibit is the Tarbosaurus bataar, a close relative of Tyrannosaurus rex and a symbol of the country's fight against fossil smuggling.
The museum is most rewarding if you are curious about palaeontology, geology, or the landscapes you will see outside the capital. It pairs well with the nearby history and art museums around central Ulaanbaatar.
