The
fauna of the Bayan Mandahu is very similar in composition to the nearby
Djadochta Formation, and the two may have been deposited at roughly the same time. These two formations share many of the same
genera, but differ in the makeup of
species. For example, the most common mammal in the Djadochta is
Kryptobaatar dashzevegi, while in the Bayan Mandahu, it is the closely related
Kryptobaatar mandahuensis. Similarly, the dinosaur fauna of the Djadochta includes
Protoceratops andrewsi and
Velociraptor mongoliensis, while the Bayan Mandahu contains
Protoceratops hellenikorhinus and
Velociraptor osmolskae.
