Although Mesozoic fossils are quite common in the Gobi Desert of
Central Asia, it is often difficult to correlate among different
localities because of a dearth of rocks amenable to absolute dating.
Specifically, correlating between the eastern Gobi Desert and more
western localities has been challenging. Here we give a
Santonian-Campanian age for the enigmatic Zos Canyon beds in the
Nemegt basin. This is based on the occurrence of the primitive
ornithopod dinosaur Haya griva at both eastern Gobi exposures of the
Javkhlant Formation and the Zos Canyon locality.
