The Flaming Cliffs site (also known as Bayanzag, Bain-Dzak or Bayn Dzak) (Mongolian: Баянзаг rich in saxaul), with the alternative Mongolian name of Mongolian: Улаан Эрэг (red cliffs), is a region of the Gobi Desert in the Ömnögovi Province of Mongolia, in which important fossil finds have been made. It was given this name by American paleontologist Roy Chapman Andrews, who visited in the 1920s. The area is most famous for yielding the first discovery of dinosaur eggs. Other finds in the area include specimens of Velociraptor  and eutherian mammals. It exposes rocks of the Djadochta Formation. It is illegal to remove fossils from the area without appropriate permits.
The nickname refers to the red or orange color of the sandstone cliffs (especially at a sunset),.
The following are dinosaur fossils that have been found in the Flaming Cliffs.
