Dzunbain Formation

Early Cretaceous geologic formation in Mongolia

The Dzunbain Formation (also known as Dzunbayn Formation) is a geological formation in Mongolia, dating to the Early Cretaceous (Aptian-Albian).^[1] The formation contains fossils of mammals, reptiles, turtles and dinosaurs. The Dzunbain Formation is equivalent to the Khuren Dukh Formation.^[2]
