Gobi Desert

The Gobi is the largest desert region in Asia. It covers parts of northern and northwestern China, and of southern Mongolia. The desert basins of the Gobi are bounded by the Altai Mountains and the grasslands and steppes of Mongolia on the north, by the Hexi Corridor and Tibetan Plateau to the southwest, and by the North China Plain to the southeast. The Gobi is made up of several distinct ecological and geographic regions based on variations in climate and topography. This desert is the fifth largest in the world.

Geography
The Nemegt Basin in the northwestern part of the Gobi Desert (in Mongolia) is famous for its fossil treasures, including early mammals, dinosaur eggs, and even prehistoric stone implements, some 100,000 years old.
