Dinosaurs: Restoring Mongolia's fossil heritage bbc.com

The Gobi Desert produces stunning fossils but many Mongolians never get the chance to see them.
Eighty million years ago, during the Cretaceous Period, Mongolia's Gobi Desert was a dinosaur's paradise of vast valleys, freshwater lakes, and a humid climate.

Mammal-eating velociraptors, lizard-hipped sauropods, and spike-armored ankylosaurs could have been spotted roaming in what are now the Martian red sandstone spires of Bayanzag's Flaming Cliffs.

These prehistorically favorable conditions make the Gobi Desert the largest dinosaur fossil reservoir in the world.
