Nemegt Basin

The Nemegt Basin is situated in the northwestern part of the Gobi Desert, in the Ömnögovi Province in the southern part of Mongolia. It is known locally as the valley of the dragons, since it is a source of many fossil finds, including dinosaurs, dinosaur eggs and trace fossils.

The main geological formations in the area are named the Nemegt Formation, Barun Goyot Formation and Djadochta Formation, in order of age, from youngest (most superficial) to oldest (deepest).
