  Iren Dabasu has at least one dinosaur in common with
the Baynshirenian beds of Outer
Mongolia-Alectrosaurus. There is no doubt that the
Baynshirenian beds far underlie the Nemegt.

 Nemegtian taxa were very wide ranging. Tarbosaurus
occurs in southern China, well south of Iren Dabasu
where Alectrosaurus is known. The absence of
Tarbosaurus there, like the absence of Mesolanistes,
and Mongolemys etc argues against a Nemegtian age.
